Chart Type "Column" and x = 0

Question

Hi all!

Problem:

Chart with ChartType "Column" does not display DataPoint (0,10) at x-Axis correctly.

The DataPoint is displayed at x-Axis value 1 and not 0! With ChartType "Line" it works.

Example:

chart1.Series[0].ChartType = SeriesChartType.Column;
chart1.ChartAreas[0].AxisX.Minimum = -5D;
chart1.ChartAreas[0].AxisX.Maximum = 5D;
chart1.ChartAreas[0].AxisX.Interval = 1D;
chart1.ChartAreas[0].AxisX.IsStartedFromZero = false;

chart1.Series["Series1"].Points.AddXY(0D, 10D); // displayed at x = 1

What is missing?

Answer 1

I tried to explain this in the FAQ, here.

Though I'm pretty sure it's not working with the Line chart type either. I don't know how you managed that. One point on a line chart won't be visible at all, unless you specify a marker. And, based on what I just tested, a line chart will also draw that marker at x = 1.

Thank you very much!

I've solved this problem by adding a new series (dummy) with Color.Transparent and insert DataPoint (1,1)
