Environment

  • Tableau Desktop

Answer

Color legends are not available for density marks Below are possible workarounds.
 

Workaround 1

If you want to divide the marks with the exact number, follow this KB: "Creating a Custom Color Scale for Varying Ranges of Data

Workaround 2

If you want to answer the question "How many marks are within a 1km radius from this location". A better way to measure it would be to use the Buffer calculation.

Workaround 3

In a new sheet, add dimension to detail, value to color, and pick the Square mark. It will build a bunch of squares.
If you sort the Dimension by Measure then they will be sorted from light to dark. Then add the labels to MIN and MAX then it will be pretty close to a color legend.
