The DEVEXPRESS chart control can now process a gap (in the data source) as a null point (with points that have undefined values). You can now customize the appearance of these gaps (based on a series of view types), you can customize the spot marks, lines, and regional segments of the null point.

You can also draw the ‘mock’ point to replace the gap (based on the adjacent series points), set the EmptyPointOptions.ProcessPointS property of the series view to ‘Interpolate’.
