Currently, the “scale reversed” checkbox in the chart settings for heatmap-style visualizations just mirrors the legend (if it is turned on) but does nothing to the color assignments in the reports. I’m not sure what the intention behind this behavior is, but it would be nice if that button instead inverted the color assignments.
Ex: in a normal scale set to 0-10, 0 = Green and 10 = Red. When the Scale Reversed checkbox is clicked, that should switch to 0 = Red and 10 = Green. This would be quicker and easier than changing the colors for the top and bottom of the range manually, and would be a more intuitive behavior for an option labelled “scale reversed”.
