Scrolling issue with Non Numeric X-Axis labels

[SivaPrasad Bevara]

Hi,

I am using Bar Chart for dipslaying the Categories and its counts.
I am displaying the Category Name in the X-Aixs. I have 16 Categories to display in the X-Axis.
The category labels are overlapping, when I display all the categories. So I wanted to use the scrolling for displaying the Categories.

I tried scrolling with the following code.

ZoomScrollSettings zoomSettings = new ZoomScrollSettings();
zoomSettings.ScrollMode = ScrollMode.ScrollOnly;
_chartArea.ZoomScrollSettingsX = zoomSettings;

But it is not working. It is just shrinking the Items within the Chart Area.

In all the examples I have seen, the scrolling is implemented with the Numeric X-Axis labels.

Please provide some samples for implemeting the scrolling with Non Numeric X-Axis labels.

I tried with setting the LabelStep. I think it will element some categories. I want to display all the categories with scrolling.

Please help.

Regards,

Hello Sivaprasad Bevara,

We have had an issue when using the ScrollOnly mode in the 2011.Q2 release ( version 2011.2.712 ), that has been fixed for the Service Pack ( version 2011.2.920 ), which caused the scroll bar not to be displayed.

In order to display only a specific range from the axis you would need to set the RangeStart, RangeEnd and also SliderSelectionStart and SliderSelectionEnd properties. Here is a sample code snippet demonstrating how to set the Zoom/Scroll setting for the X axis :

<telerik:ChartArea.ZoomScrollSettingsX>
                            <telerik:ZoomScrollSettings ScrollMode="ScrollOnly" RangeStart="0.2" RangeEnd="0.4" SliderSelectionStart="0.2" SliderSelectionEnd="0.4"/>
                        </telerik:ChartArea.ZoomScrollSettingsX>

This way scrolling would work for numeric, as well as categorical values.

Hope this helps.

Kind regards,
