Zoom logarithmic chart?

[Roger Norris]

Hello,

We would like to use Syncfusion's built-in zoom feature on a chart. We turn it on like this:

this.chartControl1.EnableXZooming = true;
this.chartControl1.EnableYZooming = true;

However, we've noticed that the zooming doesn't appear to be working on our Log-Log chart (both axes set to logarithmic). The user can still drag a rectangle, as if specifying a zoom region, but nothing happens when the mouse is released.

If we set the axes back to Double instead of Logarithmic then the zooming works again.

Is there any way to get the zooming to work with a Logarithmic chart?

Please take a look at the attached sample.

The above sample exhibit the key zooming feature in Logarithmic axes.

Please let me know if this helps.
