Summary Statistics for Thematic Map Legend

[RichardMaaranen]

When you insert a thematic map legend into a map layout, you should have the option to include automatically additional column(s) that display select summary statistics for each map class such as: number of elements (geographic areas), proportion of elements, sum of elements, number of excluded elements.

I always have to get number of elements from under Symbiology -> Classify and then click on each class and look at the number displayed at the bottom of the screen. Then write the numbers down and calculate the proportions/percentages in another program like Excel. Then type them into my map layout with the text tool. Not very convenient.

I have a similar problem in trying to replicate the number of clusters like esri does as a default when performing density based clustering. Solution was to create a summary table with the values I want then join back to the base feature layer and create the following dynamic text in the legend

Press the expression

I also created a dynamic title in the map to reflect the current definition query since I put different results of a clustering into a single featureclass.

Press the expression button

Hope this gives you some ideas
