Anyone know how to set Drag Area while Zooming?

Post by kbj0109 » Mon Jul 02, 2018 9:37 am

Dear Genius.

I want to control the area to be Zoomed,
so force to drag either entire area of Axis while user drag on the other Axis.

Can you see the picture I post? These pictures are captured from other chart that has a function I want.

Dragged area of X_Axis only matters, and Y_Axis always gets fully dragged.

Can I control the dragged area to be Zoomed?
I believe it's possible, but cannot find how.

Does anyone have example code that I can follow?
ZoomPanOptions or ZoomByFactor seem to have what I want.. but don't know how....

Hope I get help here.

The answer was
chart.ViewXY.ZoomPanOptions.RectangleZoomDirection = RectangleZoomDirection.Vertical;

Sorry for the late reply. It was busy week so forum was neglected.

LightningChart has extensive list of properties, which modifies zooming & panning behavior. This and many more setting could be found in User's Manual chapter 'Zooming and panning'

All the best.
