Gaps with XyDataSeries<DateTime, int>()

Hello François,

Thank you for contacting us.
Unfortunately, there is no way to add NaN values when you use the int data type for the DataSeries.

The recommended approach would be using float or double values instead.
Alternatively, you can exclude a part of the series with PaletteProvider using some special int value:
