As an oil & gas user, it would be incredibly helpful to be able to see different colors and scales for the "color by" item on a map chart. I could have a property control passing through one or many columns of data into the color by axis and ach of those columns could be color/scaled based on a defined color scheme grouping. This would keep a single map visible at all times and allow us to quickly see how the same group of wells are doing across many variables.
