customize heatmap in advance xml

[klee310]

hi, does anyone know how or if it is possible to customize the colors displayed in each cell of a table using heatmap?

from what i can tell, the underlying code generates a heat value for all cells in a table, then apply a shading of the color red to each cell - depending on this heat value.

however here's the problem: my table is configured to display percentages. therefore value range between 0 and 100, however if the actual result table only has 21.999 (for example) as the highest value, then this value is given a heat value of 1.0; hence displayed with the darkest shade of red.

i want to be able to customize the way this heat value is calculated, or perhaps provide a range like the rangemap command.

anyone with thoughts and comments are welcome.

thanks in advance.

The Module you're looking for is DataOverlay, but there are no parameters to help you change the colors.
It can absolutely be done by customizing the css.

Start by looking at the answer here and follow the trail. You'll find examples of using css and javascript as well as a reference to an app that provides examples of how you might implement it (the app is for rowcolors).
