Hello guys!

I´m using a Heatmap in my application, but for me would me nice if i could let the points with of the Data[i,j] = 0, in the White color, or maybe transparent if possible ....

That is important, because i will put another kind of series above the heatmap, so it will be good for a better visualization ...

Thx for all =D

Could you post it here? I'm trying to do exactly that and have no clue! I'm new to Oxyplot!

Ok, solved, here's the solution (this is Objo's answer to another thread):

You can create your own palettes like so:
var palette = OxyPalette.Interpolate(NUM_COLORS, COLOR_FROM, COLOR_TO);
So in this case, we'd like to have:
var palette = OxyPalette.Interpolate(50, OxyColors.White, OxyColors.Black);
Pau.
