Maintain Zoom View

[Shawn]

Hello,

I'm using the TimeLine in a live data application I'm working on. In the same application I'm also using the ChartView control. I love the way the ChartView's zooming works when it maintains the zoom location when the user sets it even as more data is added to the chart. Is there a way to keep the TimeLine's zoom location as more data is added?

Thank you,
Shawn

Hi Shawn,

The RadChartView and RadTimeLine are controls that are different in nature and implementation. The chart view uses a pan and zoom feature (which allows this behavior that you describe) whilst the time line needs to be told exact values (VisiblePeriodStart and VisiblePeriodEnd).

In short - this can not be achieved with out-of-the-box means. However I think that you might be able to get these results manually. I am not familiar with your scenario but may be you can manually calculate (when a new item is inserted) the new values for VisiblePeriodStart and VisiblePeriodEnd.

I have attached a simple project that should get you started.
