Zoom in for the whole control?

[Liang]

Does the ChartWebControl support zoom in or out for the whole control?

And in the help file I see such a snippet and does these work for ChartWebControl?
How if it could?
Thanks!

Hi Liang,

The Essential chart supports zooming feature in the ChartWebControl. To enable zooming along
X axis, use the EnableXZooming property and to enable zooming along the Y axis, use
EnableYZooming property.

To display the chart points,

* Essential chart includes both Zoom in and Zoom out functionalities.

* Zooming is supported on both X and Y axes.

* It is also possible to zoom on Multiple Y axes.

Please refer the sample browser sample from the below link which illustrates the above:

C:\Documents and Settings\User Name\My
Documents\Syncfusion\EssentialStudio\5.2.0.25\Web\chart.web\Samples\2.0\UserInteraction\Zoom
ingAndScrolling\CS

The above sample demonstrates customizing zooming factors for both X and Y axis at run time using the below code:

// Customizing X axis Zoom Factor

protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
{
if (CheckBox1.Checked)
{
this.ChartWebControl1.PrimaryXAxis.ZoomFactor = Convert.ToDouble(this.ListBox1.SelectedValue);
this.ChartWebControl1.Redraw(true);
}
}

// Customizing Y Axis Zoom Factor

protected void ListBox2_SelectedIndexChanged(object sender, EventArgs e)
{
if (CheckBox2.Checked)
{
this.ChartWebControl1.PrimaryYAxis.ZoomFactor = Convert.ToDouble(this.ListBox1.SelectedValue);
this.ChartWebControl1.Redraw(true);
}

}

Please let me know if this helps you out.

Regards,
Raji

Thanks for the quick reply.

I will tell you next day.

I think the feature you told me is zooming on the x and y axis.

What I need is: like in IE, when we click "CTRL +" the whole page is zooming in. And I want the whole chartwebcontrol zooming in.

Thanks
