Custom laber for AxisY and AxisY2

[Giovanni]

Is it possible to set custom label for the Y axis like in an specific value in the chart

I'm trying the following code:

 Telerik.Charting.ChartAxisItem customy;

                customy = new ChartAxisItem();

                customy.Visible = true;
                customy.Value = 0.5;
                customy.TextBlock.Text = "Custom 1 ";
                this.RadChart1.PlotArea.YAxis2.AddItem(customy);

Hello Giovanni,

You have two options:

• Set RadChart1.PlotArea.YAxis2.AutoScale to false. Now it is your responsibility to provide the axis items. You can use AddRange to add several items or AddItem to add a single item.
• Leave RadChart1.PlotArea.YAxis2.AutoScale to its default value (true). Wire BeforeLayout event. At this stage of the control lifecycle the axis items are already created, so you can modify them. Here is an example: RadChart1.PlotArea.YAxis2.Items[1].TextBlock.Text = "My CustomText";

You can find more details about RadChart axes here.

When i use autoscale = false and try to render my own Axis seems that the control puts them randomly not like in the specific value that i assigned in the Axis.Value, so maybe can you give me an example of how to do that. is lie i'm trying to mark some specific points in the chart.

Hi Giovanni,

RadChart will put the ticks (major and minor) on even intervals on Y axis, while the axis items will respect the Value property. Unfortunately, you cannot force a tick to appear at a certain position. You might calculate the step, so that the custom value matches a certain tick. Please, find a sample attached to this thread.
