Changing MinValue on AdditionalYAxes

[Annie]

I would like to have the ability for end user to changing MinValue, MaxValue & Step for Y Axis in Line Chart. I am able to apply it to my Primary Y Axis, but unable to my Secondary Y Axis. Below is the code snippets I am currently using for my user to changing MinValue & MaxValue on primary Y Axis.

this.RadChart1.DefaultView.ChartArea.AxisY.MinValue = Min1;
this.RadChart1.DefaultView.ChartArea.AxisY.MaxValue = Max1;

Please point me the way to have it on Secondary Y Axis.
All the changes is upon user request/on runtime.

Many thanks.

Hello Annie,

In order to define the secondary Axis min, max and step values you should first create new instance of AxisY class, define its object properties and then add it as AdditionalYaxes to the chart. You should also set your SeriesDefinition.AxisName a name and then set the same name to the second Axis you've already created.

It can be achieved like this:

SeriesMapping secondSeriesMapping = new SeriesMapping();
secondSeriesMapping.SeriesDefinition = new BarSeriesDefinition();
secondSeriesMapping.SeriesDefinition.AxisName = "secondary";
secondSeriesMapping.ItemMappings.Add(new ItemMapping("Title", DataPointMember.XCategory));
secondSeriesMapping.ItemMappings.Add(new ItemMapping("Value2", DataPointMember.YValue));

AxisY axisY1 = new AxisY();
axisY1.AxisName = "secondary";
axisY1.AutoRange = false;
axisY1.MinValue = 0;
axisY1.MaxValue = 100;
axisY1.Step = 5;

radChart.DefaultView.ChartArea.AdditionalYAxes.Add(axisY1);
radChart.SeriesMappings.Add(secondSeriesMapping);

Hope that helps.
