Question summary

How can I vary the thickness of the edges/lines of polygons when they are symbolized using the "Bivariate Colors" option?

Explanation, context and what I tried

When I symbolize a polygon layer using the "Graduated Colors" symbology option, I can edit the thickness of the polygon's edges/lines using the "Format all symbols" item inside the "More" drop down menu.

Graduated Colors

However, when I symbolize a polygon layer using the "Bivariate Colors" symbology option, I simply cannot find a way to edit the thickness of the polygons' lines/edges.

Bivariate Colors

I've tried all of the sub-menus, but wasn't able to find out where this can be edited. I even tried a workaround of using the "Vary symbology by attribute" and setting a constant value, but that didn't work either:

Vary symbology by attribute

Software version

I'm using ArcGIS Pro 2.9.3.

If you want to change thickness of all edges you click on the template icon


Here is an example of setting the border on a bivariate colour scheme to a gradient stroke for a cool effect.

I don't think you can change the thickness of individual colour scheme polygons, well I've not worked out how.
