Maximum Zoom in - Timebar control

[Balaji]

Hi,

We have set the Interval (Decade, year , month, week, day )in our time bar control and privided the some test data for it.
However we were not able to zoom -in aftre month level, if we give larger date range in Timebar Period start and End(1-Jan-1950 to 1 jan 2010).

If we reduce the time range then we were able to zoom-in till week and day level?

Is that some zoom -in level do we need to set so that it start from Decade  and go till  Day or Hour.

Also if we set more time range , we are not getting the Bar/Spike in RadColumnSparkline control, PLease let me what i am doing wrong?

I have also provide the XAML

I am affected by a similar issue.Depending on the periodstart/periodend, the zooming
beyond day level (eg hour) does no longer work.
Using a 30 day period, it does not work.
Using a 20 day period it works.

Is some work around available?

Best regards,
Henri

Hi,

Due to a limitation in Silverlight framework, we have enforced a constraint for zoom-in to maximum of 30 000 pixels. Depending on the period range that the timebar shows, the minimum interval that can be displayed, might be different from the minimum interval that you have added in the Intervals collection. In your case the period range of your timebar is large and when you try to zoom in to a smaller interval, you hit the 30 000 pixel limit.

All the best,
Yavor
