Hi. I'd like to show two 2D heatmaps in one single figure. For this purpose, I give some transparency to the heatmap on top. But I want the transparency be non-constant: 100% for the color corresponding with the lowest value in the heatmap on top and 0% for the color corresponding with its highest value.
This can be easily done in VisIt, as the opacity option of a plot can take a value called "ramp". I'd like to do the same in Origin. Can it be done?
