Hello everyone,

I am trying to make a choropleth maps of same variable (Median Home Value) over different time period to compare them visually.  In attached maps, visual comparison might be misleading since highest data range has same color ( dark pink) but their value are different. Is there way to set color ramp according to data range (Min/Max value)?.

Thanks

In the symbology, import the color ramp and ranges rather than setting them individually. So just set the first layer and then copy the symbology to each other version. This way the color ramps will be the same across all of your features regardless of their actual values. I sometimes cheat and make a dummy polygon with the lowest value and highest value of my entire actual datasets and then set the symbology on this layer. I then use the the dummy layer in 'import symbology'
