How reduce the height of an mschart by breaking up the y-axis

How can I reduce the height of an mschart like this:

Chart with flat area

[EDIT] In my case I do not want break chart view.

You seem to be looking for AxisY.ScaleBreakStyle.

Here is an example:

enter image description here

Series s = chart1.Series[0];
ChartArea ca = chart1.ChartAreas[0];
Axis ay = ca.AxisY;
s.ChartType = SeriesChartType.Line;
for (int i = 0; i < 100; i++) s.Points.AddXY(i, rnd.Next(100) + 50 );
s.Points.AddXY(s.Points.Count, 123456);

ay.ScaleBreakStyle.Enabled = true;   // <<<=== enable or disable!
ay.ScaleBreakStyle.LineWidth = 1;
ay.ScaleBreakStyle.LineColor = Color.OrangeRed;
ay.ScaleBreakStyle.StartFromZero = StartFromZero.Auto;
ay.ScaleBreakStyle.Spacing = 2;
ay.ScaleBreakStyle.StartFromZero = StartFromZero.Auto;

Note that there a quite a few cases where it will not work. MSDN:

Scale breaks are not supported under any of the following conditions:

  • Pie, doughnut, funnel, pyramid, radial or any stacked chart types are used.

  • Custom intervals for labels, tick marks or grid lines are enabled.

  • The minimum or maximum value for the axis is set.

  • Custom labels are used.

  • A logarithmic Y-axis is specified.

  • Axis views on the Y-axis, which include scrolling and zooming, are used.

  • 3-D charts are used.

Update: Of course you can also disable the break at runtime..
