Chart in winform displaying wrong Point

Question

I have the following code. I have hardcoded the x and y values to test. And for some reason for the point (0,-0.5) it plots (1,-0.5) For the life of me I do not know what is goi

Answer 1

This is really weird! Looks like a very hard to believe bug. I played around but can only confirm that there seems to be no way to set a single Point to position 0 in a Series.

Here is a silly workaround:

S1.ChartType = SeriesChartType.Point;

for (int i=0; i < 2; i++)
{
    DataPoint point = new DataPoint();
    point.SetValueXY(i, -0.5);
    if (i > 0) point.Color = Color.Transparent;
    S1.Points.Add(point);
}

I wish I knew what this is about - Chart is so ill-documented there might still be some system to the madness..

Update: When you add a Timer and let its Tick remove the transparent 2nd Point, you can see how the 1st Point jumps from 0 to 1. So weird..
