I want to have Y axis starting at 0 at the bottom and max value at the top, but I also want 0 index in heatmap data buffer to be displayed at the max value. I was able to achieve that using your HeatMapExampleView by modifying CreateSeries method like this

return new Heatmap2DArrayDataSeries<int, int, double>(data, ix => ix, iy => h - iy);

Note the iy => h – iy. What I noticed is that after doing that the RolloverModifier stopped working. How can I fix this or is this a bug?
