How do I display a line graph with breakages in the line when a graph has hidden points?

[elektra]

 I want to hide many points of the line graph; I saved the indexes of the points to hide in a list ( 286 Points):

foreach (int tempPointIndex in hiddenPoints) {   mainChart.Data[seriesId, tempPointIndex] = Chart.Hidden;}

The result: the line is broken at the first hidden point.

how can I display a line with many hidden points (more than 280) with different indexes in the chart?

You can have hidden points at any location in the chart. For example:

chart.Data.Points = 30;

chart.Data[0,3] = Chart.Hidden;

chart.Data[0,8] = Chart.Hidden;

chart.Data[0,18] = Chart.Hidden;

// All other points set to valid data

Will produce 3 breaks in the line.
