I'm using a candlestick chart and evrything works fine as long as the Y axis Auto range propoerty is set to TRUE.
I want to manually restrict the Y-axis range and I type in the following code:
I want to manually restrict the Y-axis range and I type in the following code:
candleStickChart.DefaultView.ChartArea.AxisY.AutoRange =
false;
candleStickChart.DefaultView.ChartArea.AxisY.AddRange(0,50000, 1);
But this causes the page to freeze and the chart doesn't get created. I believe this is a performance issue and looked up the following page:
http://www.telerik.com/help/silverlight/radchart-performance-tips-and-tricks.html
and found this:
Specify fixed axis range manually - if your data changes a lot, but you know the ranges over which it will vary, you can disable the Axis auto-range algorithm and specify the Axis range manually. This will probably lower the processing time a bit.
But in the contrary , the processing time is increasing when i do this.
Am i missing something here?

Hi AM,
The reason for this is that you are choosing a step of just 1. In this way the axis needs to create 50000 axis ticks. Even if RadChart created them I believe the chart would be pretty unusable and extremely busy. You might want to try using a step of 5000 instead. Try it like this:
candleStickChart.DefaultView.ChartArea.AxisY.AddRange(0,50000, 5000);
It will look better and will perform very fast.
