edit bi-variate choropleth map symbology

Anonymous User — Tue, 28 Feb 2023 15:15:40 GMT

I'm creating a bi-variate choropleth map in ArcGIS Pro and would like to edit the symbology. When I rotate the symbology or set my own colours they display correctly in the map but one of the field colour ramps is incorrect. Does anyone know how to fix this? I believe the second colour ramp in my screen capture should transition from turquois to white, not pink to purple.

Looks as expected to me. Those are the monovariate (is that a word?) ranges. low to high for each variable.

What's your reasoning for turqoise to white?

Oh I see what's happening in my screen capture now. One of my variables is prevalence of low income. I wanted to rearrange the colour ramps so that when variable 1 is low & variable 2 is high ((prevalence of low income) the polygon appears white (i.e. variable 1 is low, and income is low). I had to think a bit about what prevalence of low income really means - a high values mean that low income prevails, low values mean that high income prevails. Instead of playing with the symbology I just flipped the values around so that a low number = low income. ((PrevalenceofLowIncome * (-1)) +100)
