Zoom in on specific data

[Trude]

If I have a bar chart with for example 10 bars (either 10 series or 10 bars in the same series); is it possible (via code behind) to zoom in on the top three (or any number)?

Hi Jorn,

You can zoom in on a specific item or set of items from the RadChartView from code-behind like this:

int startIndex = 2;
int endIndex = 5;
int count = this.data.Count;

double selectionStart = (double)startIndex / count;
double selectionEnd = (double)endIndex / count;
var panZoomBar = Telerik.Windows.Controls.ChildrenOfTypeExtensions.ChildrenOfType<PanZoomBar>(this.RadChart1.HorizontalAxis).FirstOrDefault();
panZoomBar.SelectionStart = selectionStart;
panZoomBar.SelectionEnd = selectionEnd;

In the example above, the chart will zoom in horizontally on the items with indexes 2, 3 and 4.

All the best,
