Hi Experts,

I want to display data in a NHeatMapSeries. If X and Y data is positive, it is working nice. But when I have negative X-values, only the values with positive X / Y values are displayed:


Data is feed to the Chart like:
nevSeries.Data.SetValue(iX, iY, fValue);

when I change the Origin:
      nevSeries.XValuesMode = HeatMapValuesMode.OriginAndStep;
       nevSeries.OriginX = - 40; // -0.5; fXMinMax[0]
       nevSeries.StepX = 1;
It looks like that:

But it should look like a full circle. Are there any special settings to be made for negative X-Values ?

Thanks for the help,
Best regards,
Joern

... thanks a lot for the detailed example. Now I added a manual offset for negative coordinate values and with this work-around all is displayed properly.

May be it would be a good enhancement for a future Nevron Chart version if the heatMapSeries would also support negative coordinate values so that no manual offset is necessary?

Thanks again & best regards,
Joern
