Hello
Do heatmap dataseries support logarithmic axes? i have a heatmap chart and a line (pic 1), which need to be drawn in logarithmic scale, but i get no heatmap chart and the line is drawn correctly (pic 2) when switch axis type to logarithmic. Something i’m likely to get is on pic 3 .
thanks in advance

Hi Alexander

The reason for the blank chart is your UniformHeatmapDataSeries contains zeros on the X or Y axis, which is invalid data for a LogarithmicAxis chart.

To correct this, ensure that the UniformHeatmapDataSeries.StartX, StepX, StartY and StepY properties do not result in a 0 on the X or Y axis, or crossing zero.

This will cause the heatmap to display.

However, the heatmap still won’t scale according to the log X or Y axis, it will simply show. I don’t know if we can support this easily. I’ll ask the team but no promises.

Best regards,
Andrew
