Hello, I'm using CXTPChartControl to draw some charts. But some of my data is missing and I have to input NULL value, however, no matter I choose CXTPChartBarSeriesStyle or any similar styles, the control will use 0 to replace NULL and draw many zero values.

If I drop all the NULL values, the interval for the AxisX will be quite different, so I must keep these missing values. Please tell me how to make the control do not show NULL as zero...

Thank you very much...
