Hello!

I use three kinds of series in my application: TFastLineSeries, TPolarSeries and TSmithSeries. I use them on the same chart. If I try to zoom a picture it works well with the TFastLineSeries, but I have no effect when my current series is polar of smith-chart. Why?

Is it implemented? If no, how could I implement such functionality myself?

So, no answers. Does it mean nobody in a support team knows this? I really need the zoom functionality for these series

Hi Alexey,

Zoom is not implemented for those series. You could zoom the whole chart using the TCommander button for it or implementing that using Chart1.ZoomPercent method.

Hi!

I've tried to use this method. But I've got problems with it.
I handle a left mouse click and call Chart1->ZoomPercent(50);
The help says it should zoom in the picture. But I see that picture is zoomed out. Moreover, TSmithSeries doesn't change anything. TPolarSeries become zoomed out but the coordinate center is shifted after each call. And it's not a zero.

What is wrong in this procedure?

Hi Alexey
unfortunately I don't have time to experiment it myself right now., but i am in hte same situation as you are. I use the same 3 series so please let me know if you find any solution to this problem.
I'll check it myself whern i have time, but not before next month at least.
thx^^

So, I don't see any answer once more. Does it mean the support doesn't know how to solve the problem and why the proposed function doesn't work?

Hi Alexey,

sorry for delay, I'm afraid the TChart is not prepared to combine these three Series types with zoom functionality. For the moment I've not found a way around this.
