Regarding Zooming and Tooltip on ChartWeb Control

[Alok]

Hi,

I have doubt regarding zooming on web control. according to latest online documentation, it supports two ways of zooming:
1. using Either EnableXZooming(), EnableYZooming()
2. Secondly setting ZoomFactor, ZoomPosition values.

I want to know what is difference in their working like do both require reloading of web form, some thing else like that.

And one more thing do web form control supports interactive tooltip like windows form.

Thanx and Regards,
Alok

Hi Alok,

1.EnableXZooming() and EnableYZooming() properties are implemented only in Windows chartControl and not yet in ChartWebControl.
The updated documentation will be uploaded within 2 days or so.
Sorry for the inconvenience caused.

2.You can Zoom using Primary X and Y Axis ZoomFactor''s and Zoom Position''s.

ZoomFactor : This factor is used to calculate the Zoomed Range.
ZoomPosition: Minimum value (ZoomPosition) displayed on this axis, when zoomed as a fraction of the total range.
For example if the total range is 20 and the minimum value currently displayed is 10, the ZoomPosition will be 0.5 (10/20).

3.A feature request for UserInteractive Tooltip has already been created and will update you as soon as the feature is implemented.

Hi Rashida,

When we use zoom feature on chart web control using ZoomFactor and ZoomPosition, do it requires to reload the complete web page to refresh the chart.

Hi Alok, When any Web control is used to set the ZoomFacter and ZoomPosition in a Web Page, PostBack occurs. There is an alternative way to set the ZoomingFactor and Zooming Position without PostBack using ChartWebControl1_RefreshCallback() Event and RefreshFrequency property in ChartWebControl. Please refer to the attached sample. Let me know if this fulfills your requirement. Thanks for your interest in Syncfusion product. Regards, F.Rashidha.
