To achieve the desired effect you need to set to both axes the same minimum and maximum values. In order to do so you need to set a couple of properties. Please refer to the online help topic
and the code snippet below.
additionalAxis.AutoRange = radChart.DefaultView.ChartArea.AxisY.AutoRange =
additionalAxis.MinValue = radChart.DefaultView.ChartArea.AxisY.MinValue = -120;
additionalAxis.MaxValue = radChart.DefaultView.ChartArea.AxisY.MaxValue = 120;
additionalAxis.Step = 10;
radChart.DefaultView.ChartArea.AxisY.Step = 10;
You have to set for both axes the AutoRange
property to false. Then the MinValue
properties have to be the same, as well, so that the values on both axes are aligned. Have in mind that when you disable AutoRange
requires you to set the Step
property. For the two axes, two different values can be set.
