You have data with a range of values, and you want to represent it on a map using symbols that range in size. Sounds simple enough. But it turns out there is more than one way to size your symbols in ArcGIS Pro, including Graduated symbols<\/em>, Proportional symbols<\/em>, Vary symbology by attribute<\/em> and Symbol property connections<\/em>. How do these work differently and how do you know which one you want to use?<\/p>\n

This map only has 6 sizes, not a continuous range of sizes. You get to decide how many people a settlement needs before it qualifies as a small town vs a large town. And if you don’t know where to make the break there’s a number of different methods<\/a> available for classifying your data, including Natural Breaks<\/em>, Quantile<\/em>, and Standard Deviation<\/em>.<\/p>\n

PROPORTIONAL SYMBOLS<\/strong><\/a>
\nUse this if you want to show a continuous range of sizes instead of discrete classes. But there’s more to it than just that. In fact there are three different ways to use this symbology method:<\/p>\n

Size range<\/strong>
\nUse this if you want the simplest representation of your data as size. Pick a min size – your smallest village will draw at this size. Pick a max size – your largest megacity will draw at this size. All other towns will scale between these min and max sizes.
\nHint:<\/em> Use the histogram to understand how your data is distributed. In the example below, almost all of the values are going to draw with small symbols, thanks to an outlier of 3 million. Also note how those pesky -99999s, meant to represent null values, are skewing the results:<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":196642,"id":196642,"title":"Untitled picture","filename":"Untitled-picture.png","filesize":3541,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/mapping\/arcgis-pro-size-guide\/untitled-picture-2","alt":"histogram ranging from -9999 to 3 million","author":"7411","description":"","caption":"","name":"untitled-picture-2","status":"inherit","uploaded_to":196542,"date":"2018-05-26 20:57:53","modified":"2018-05-26 20:58:34","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":250,"height":282,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture.png","thumbnail-width":177,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture.png","medium-width":231,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture.png","medium_large-width":250,"medium_large-height":282,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture.png","large-width":250,"large-height":282,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture.png","1536x1536-width":250,"1536x1536-height":282,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture.png","2048x2048-width":250,"2048x2048-height":282,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture.png","card_image-width":250,"card_image-height":282,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture.png","wide_image-width":250,"wide_image-height":282}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

Now features with a value of 0 or less will draw with the minimum size, and features with a value of 800,000 or greater will draw with the maximum size.<\/p>\n

True proportional size<\/strong>
\nUse this if you want to draw symbols which are truly proportional to one another. For example: City A has a population that is twice as large as City B, so you want Symbol A to draw twice as large as Symbol B. To accomplish this, choose None<\/em> as the max size. Now your smallest value will draw with your min size. All other symbols will grow proprotionally from there.
\nNotes:<\/em>
\n\u2022 Only values greater than zero will draw.
\n\u2022 Often when you choose this option, your symbols will blow up to enormous sizes, sometimes flooding the entire screen. True proportional symbols are not appropriate for all value ranges.
\n\u2022 When I say that one symbol is twice as large as another, I mean its area<\/em> is twice as large, not its point size, or diameter, or circumference. Specifically, the square root of the data value will be used as the radius to calculate the area of a circle symbol.<\/p>\n

Direct size<\/strong>
\nUse this if you want to represent the real sizes of your features. This option does not make sense for our cities example. But it does make sense if you have a dataset of trees, with an attribute representing their crown width in meters:<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":196672,"id":196672,"title":"Untitled picture","filename":"Untitled-picture-3.png","filesize":3541,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-3.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/mapping\/arcgis-pro-size-guide\/untitled-picture-5","alt":"Unit = Meters, Data represents = Radius","author":"7411","description":"","caption":"","name":"untitled-picture-5","status":"inherit","uploaded_to":196542,"date":"2018-05-26 21:01:12","modified":"2018-05-26 21:01:29","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":319,"height":76,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-3.png","thumbnail-width":213,"thumbnail-height":51,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-3.png","medium-width":319,"medium-height":76,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-3.png","medium_large-width":319,"medium_large-height":76,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-3.png","large-width":319,"large-height":76,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-3.png","1536x1536-width":319,"1536x1536-height":76,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-3.png","2048x2048-width":319,"2048x2048-height":76,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-3.png","card_image-width":319,"card_image-height":76,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-3.png","wide_image-width":319,"wide_image-height":76}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

But wait – your values represent the diameters of the trees, not their radii. So set an Arcade expression instead of a field: $feature.SIZE\/2<\/code>. Now your symbols will draw on the map at the same size as the trees grow on the ground.
\nNotes:<\/em>
\n\u2022 This option is only available if your map uses a projected coordinate system<\/a>.
\n\u2022 Your symbol choices are limited to circles and squares. That’s because calculating the area or radius of a bicycle-shaped symbol can’t be done with any real accuracy.
\n\u2022 Only values greater than zero will draw. Only magic can draw a symbol that is -3 meters large.<\/p>\n

VARY SYMBOLOGY BY ATTRIBUTE<\/strong><\/a>
\nUse this if you are already symbolizing your features with color or shape and want to vary them by size as well. Maybe your cities are drawing with a range of colors to represent average income, and you also want to vary their size to represent population.
\nYou have three options here:<\/p>\n

Size range<\/strong>
\nThis works the same way as Size range in Proportional Symbols, described above. To access this option, check the Enable size range<\/em> checkbox and a histogram will appear.<\/p>\n

Random<\/strong>
\nMaybe you don’t know how big each tree is in your dataset, you just need to show that the city has trees, and sizing them randomly will create a more realistic effect. Choose Random<\/em> from the field picker and pick a min and max size.<\/p>\n

Direct size<\/strong>
\nThis works almost<\/em> the same way as Direct Size in Proportional Symbols, described above. But it’s less strict. You don’t need to use a projected coordinate system, and you can apply it to any symbol you want. Using this option, symbol sizes are derived directly from the attribute values, and drawn using the current symbol unit<\/a>. Usually that’s points. So a town with 500 people will draw as 500 points. Clearly this is not the option you want to use for population data. But it can work well with roads, to make a 4 lane highway draw as 4 points wide:<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":196692,"id":196692,"title":"Untitled picture","filename":"Untitled-picture-4.png","filesize":40518,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-4.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/mapping\/arcgis-pro-size-guide\/untitled-picture-6","alt":"highway map of O'ahu symbolized by number of lanes","author":"7411","description":"","caption":"","name":"untitled-picture-6","status":"inherit","uploaded_to":196542,"date":"2018-05-26 21:07:30","modified":"2018-05-26 21:08:18","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":965,"height":661,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-4.png","thumbnail-width":213,"thumbnail-height":146,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-4.png","medium-width":381,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-4.png","medium_large-width":768,"medium_large-height":526,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-4.png","large-width":965,"large-height":661,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-4.png","1536x1536-width":965,"1536x1536-height":661,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-4.png","2048x2048-width":965,"2048x2048-height":661,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-4.png","card_image-width":679,"card_image-height":465,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/05\/Untitled-picture-4.png","wide_image-width":965,"wide_image-height":661}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

\nUse this to control the size of specific properties or layers within symbols. Sometimes you may want only one part of your symbol to change in size, while the rest remains the same.

Notes:<\/em>
\n\u2022 This property works in the same way as Direct Size in Vary Symbology by Attribute: if the value is 5, the symbol will draw 5 pt large. If your values range from 1,000 – 5,000, that’s going to be a problem. But don’t worry. You can use an Arcade expression<\/a> instead of a field. Maybe $feature.yourfield\/1000<\/code>.
\n\u2022 The control still says “1 pt” but when the data icon turns blue, it means that an attribute has been connected, and this will override the size property.<\/p>\n

EXTRA OPTIONS IN 3D<\/strong>
\nIf you are working in a scene, having three dimensions offers extra possibilities. If you want to, you can scale each of those dimensions separately. Use this if you want to vary symbols by perspective height or volume. Note that height and volume aren’t the same thing as size visual variable<\/a>, but they are used with similar intentions.<\/p>\n

Extrusion<\/strong><\/a>
\nUse this if you want to extrude your feature’s geometries based on a field or expression.

Vary symbology by attribute<\/strong><\/a>

Notes:<\/em>
\n\u2022 The size of the base\/width of these stretched symbols can be set by changing the size of the template symbol.
\n\u2022 Remember that perspective can skew perception of size – those symbols which are farther away will be smaller, rendering your proportional symbology inaccurate.

To summarize, there’s a lot of different ways to symbolize by size! Below is a recap to help you pick the right one for your map:<\/p>\n

Graduated symbols<\/strong>: Use this to break your data up into a series of classes or bins.<\/p>\n

Proportional symbols<\/strong>: Use this if you want to show a continuous range of sizes.<\/p>\n

Size range:<\/strong>\u00a0Use this if you want the simplest representation of your data as size.<\/p>\n

True proportional size<\/strong>: Use this if you want to draw symbols which are truly proportional to one another.<\/p>\n

Direct size<\/strong>: Use this if you want to represent the real size of your features.<\/p>\n

Vary symbology by attribute<\/strong>: Use this if you are already symbolizing your features with color or shape and want to vary them by size as well.<\/p>\n

Size range<\/strong>: Use this if you want the simplest representation of your data as size.<\/p>\n

Random<\/strong>: Use this if you want your symbols to vary in size randomly in order to create a visual effect.<\/p>\n

Direct size<\/strong>: Use this if you want to represent the real size of your features.<\/p>\n

Symbol property connections<\/strong>: Use this to control the size of specific properties or layers within symbols.<\/p>\n

Extra options in 3D<\/strong>: Use this if you want to vary symbols by perspective height or volume.<\/p>\n

Extrusion<\/strong>: Use this if you want to extrude your feature’s geometries based on a field or expression.<\/p>\n

Vary symbology by attribute<\/strong>: Use this if you want to symbolize by volume, or if you want to scale the height of a 3D symbol differently than the width.<\/p>\n

Proportional symbols<\/strong>: Use this when you want to scale only the height of a symbol, and you also want to take advantage of the special properties of True proportional or Direct size.<\/p>\n

Symbol property connections<\/strong>: Use this if you want to symbolize volume and control the size of each axis (X, Y, and Z) separately.<\/p>\n"}],"authors":[{"ID":7411,"user_firstname":"Heather","user_lastname":"Smith","nickname":"Heather Smith","user_nicename":"heather-smith","display_name":"Heather Smith","user_email":"Heather_Smith@esri.com","user_url":"","user_registered":"2018-03-21 18:21:18","user_description":"Heather is a cartographer and artist.

But there is in fact a lot of variation there. Some stars are brighter than others. And if you look closer (try binoculars!) you can see that the stars have different colors. You can use ArcGIS Pro to depict these subtle stellar differences.\n\"stars<\/a>\n\nThis tutorial delves into the Vary symbology by attribute<\/strong> option in ArcGIS Pro. You can download my project<\/a> with the data needed to follow along.\n\n\nBegin by preparing a map.\nYou're mapping the night sky, so make the background black. You can do this via Map Properties<\/strong>:\n\"Screenshot<\/a>\nAlso on Map Properties<\/strong>, you can set a Coordinate System<\/strong>. Do you live in the northern hemisphere? If so I recommend North Pole Stereographic<\/em> as a projection for this map. Otherwise, you can use its twin South Pole Stereographic<\/em>. Better yet, you could make two maps and thus cover the entire celestial sphere.\n\nIf you want to know more about using earth's coordinate systems to map the night sky, check out my other tutorial.<\/a>\n\nNext, add data to your map. Find it in p20starcolors.gdb in the project package you downloaded above.\n\"map<\/a>\nThat's what the hemisphere layers are for in the provided data. Pick whichever one you need and symbolize it with a black fill color and no outline. Now your map only shows the reasonably undistorted half:\n\"map<\/a>\nOf course, you are not mapping the earth! But the celestial sphere behaves similarly to the terrestrial one, and grossly distorted constellations are just as annoying and useless as grossly distorted continents.\n\nPlace the mask layer above the other ones. You can ignore the asterisms layer for now.\n\"picture<\/a>\n\nSYMBOLIZE BY SIZE<\/strong>\nStars are typically symbolized based on their magnitude <\/em>value. This is a measure of how bright or faint they appear from earth. A low magnitude value means a brighter star. We can easily accomplish this in ArcGIS Pro using Graduated Symbols<\/strong>.\n\"picture<\/a>\nNote that you have to make the minimum size larger than the maximum.\n\"map<\/a>\nThat looks pretty good. You could stop here. But then you would be missing the entire point of this tutorial.\n\nSYMBOLIZE BY TRANSPARENCY<\/strong>\nOn the Symbology Pane<\/strong>, click this funny little button:\n\"picture<\/a>\nAnd choose Vary symbology by attribute<\/strong>.\n\nWhat is this all about?\nWhenever you symbolize your data with anything more than a single symbol, you are using what cartographers call Visual Variables. Check out this nice chart that explains them all<\/a>.\n\nYou're already using the size <\/em>visual variable to map the stars based on their magnitude. On the Vary symbology by attribute<\/strong> page you can add more visual variables to your layer. Usually you would do this because your data contains two different attributes and you want to represent both of them at once using different means. But in this situation, you're going to do something a little different, and use the same attribute (magnitude) for two visual variables, in order to emphasize it.\n\nThe variables are size (already applied using graduated colors) and transparency. By adding transparency you can create a more naturalistic image of the night sky. It's a trick to add some depth, so that the faint stars recede even more into the background.\nHere's how you can set it up:\n\"picture<\/a>\nAnd here's what it looks like:\n\"map<\/a>\n\nSYMBOLIZE BY COLOR<\/strong>\nBut you can go farther than this.\nNormally I do not recommend using more than two visual variables at a time. It can make for some very confusing maps! But since you are using size and transparency to depict the same attribute, I think that you are ok to add color to the mix.\n\nThe star layer has a field called Color Index<\/em>. More specifically, this is the B-V Color Index<\/em>, which I do not understand well enough to describe to you here, but the gist of it is that hotter stars appear more blue in the sky, while cooler stars appear more orange. It's actually much more complicated than that, but despite this, a number of people have valiantly attempted to assign specific colors to the stars. I borrowed some hex values from the work done by Mitchell Charity:\n\"chart<\/a>\nSource: What color are the stars?<\/a>\n\nAnd then I built a color scheme in Pro using those values:\n\"picture<\/a>\nDon't bother making this color scheme yourself, not unless you enjoy tedious tasks. You can find the color scheme ready to go included with the download listed above<\/a>.\n\nBut if you ever do find yourself making a color scheme with 49 color stops, I recommend using the Evenly distrubute color stops<\/strong> option. If you look at the table above, you can see that the B-V values are evenly distributed, with a change of 0.05 between each row. Their corresponding color stops need to be just as evenly distributed if they are to match properly.\n\nBack to Vary symbology by attribute<\/strong>. Expand the Color<\/strong> section and apply the field and color scheme.\nThe numbers shown on the histogram are based on the min and max Color Index values found in the data. But the stops in the color scheme are meant to be associated with very specific B-V values, and they won't line up if the min and max are off. You need to edit these values on the histogram before the color ramp will align correctly with the data.\nJust double click on the numbers to change them:\n\"picture<\/a>\nNote that these values aren't allowed to overlap one another, so they are picky about which order you edit them in. Any stars that fall outside of the -0.4 to 2 range will either draw with the first blue color or the last orange one.\n\nThere's also a few Null values in the data. Three stars have no color index value at all, so they will be ignored by the color scheme, and draw with the fallback color. This is the white color defined in Graduated Symbols<\/strong>. You might be fine with this, but if you're not, you can exclude them from the map.\nNavigate to the Advanced <\/strong>page:\n\"picture<\/a>\n\"picture<\/a>\nAnd add a Data exclusion<\/strong>:\n\"picture<\/a>\nPress the Back<\/strong> arrow button again to return to the main Symbology<\/strong> page, and press the More<\/strong> button. Uncheck the Show excluded values<\/strong> option.\n\"picture<\/a>\nNow those three ambiguous stars will not draw on the map at all.\n\nLet's take a look at the final result:\n\"map<\/a>\nTo finish things up, turn on the Asterism layer and give it some faint symbology that doesn't distract too much from the stars:\n\"stars<\/a>\nAdding extra visual variables via the options in Vary symbology by attribute<\/strong> can make for some powerful storytelling with your data. If you use them wisely you can add more information to your map without needing to use any text. In this example, the changes are relatively subtle, but the result is a map that is easier to read - the brighter stars stand out more distinctly than before, helping you to find your bearings in the sky more quickly.\n\nTry it yourself!
