Hi there,

I would like chartArea's Y-Axis in the RadChart not to have the label as the number but as the text just like the image below
http://upic.me/i/f1/chartonoff.png


The details are
- Have Y-Axis ItemLabel as only "On" and "Off"
- X-Axis ItemLabel still be the collection of text from the XCategory
- Have no any point shown in the chart area

Is it possible to do something like this at this moment

Thanks

Hi Nikolay,

I found the problem to my customized solution about your code

The Problem is about this event

private void RadChart_DataBound(object sender, ChartDataBoundEventArgs e)
{
    RadChart chart = sender as RadChart;
 
    foreach (TickPoint tick in chart.DefaultView.ChartArea.AxisY.TickPoints)
    {
        tick.Label = MyClass.Processes[(int)tick.Value];
    }
}



According to my code, I turn off defaultViewLayout and then create own multiple chart Area with same step as this link in the code behind C#

http://www.telerik.com/help/silverlight/radchart-populating-with-data-data-binding-to-many-chart-areas.html


Then,  since I add chartArea into Grid (And grid become radChart.Content), Instead of call chartArea from the DefaultView, How can I call chartArea(s) from the Grid in the event DataBound (Suppose I have 3 chartArea in it)

Hello Woramin,

In this case the best alternative would be to subscribe to the specific chart area's AxisY.RangeChanged event :
ChartArea chartArea3 = new ChartArea();
chartArea3.Name = "Area3_Name";
chartArea3.AxisY.RangeChanged +=new EventHandler(AxisY_RangeChanged);

 instead of doing it on the DataBound event of the RadChart.

All the best,
