TChart Zooming

Hello, im using Teechart Pro 7.0 with C++Builder 6.0. I am trying to get the zooming feature of a TChart component working and im having difficulty. I am trying to make the behavior of the component such that when the user clicks and drags downwards only the Y axis is zoomed

when I:
change the Chart1->Zoom->Direction property to tzdVertical, not only does the chart continue to zoom in both horizontal and vertical directions, but the chart no longer "unzooms" when the user drags up and left, independant of what Chart1->Zoom->UpLeftZoom is set to. I have verified this with a very simple application.

Is this a bug or am I missing something else that I have to do in order to get vertical zooming to work?

Thanks,

Henry Bragg

Hi Henry,

Yes, you're correct, it's a known bug. It's on our bug list and a fix for it will be considered to inclusion for the next maintenance release. In meantime you can set the Vertical zoom (zoom style) from the Object inspector (at design time).
