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?

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 ...

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

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, h...

Hi, Narcis! Regarding the second question about surface at specific y coordinate: procedure TForm1.Chart1AfterDraw(Sender: TObject); var fp: TFourPoints; z0,z1: Integer; begin // draw plane at y(x,z) = 0 fp[0].X := Series1.GetHorizAxis.IStartPos; fp[0].Y := Series1.CalcYPosValue(0.0);; fp[1].X := Se...

Hi, Narcis! Hi Alexey, It's really hard to give you a solution without having a test application. So could you please send us an example we can run "as-is", together with data, so that we can reproduce the problem here? I'm sorry for so long silence from my side. I had a problems with some other pro...

Hi, Narcis! On 8th April I sent you an e-mail answering this question. I'm writting down my reply below: It looks like a drawing bug. Workaround(s) : switch to opengl, as the used triangle hiding algorithm does not work in all cases. I've received your e-mail, thank you. But in my previous post I wr...

I've asked here some weeks ago but I have no answer, unfortunately. I use the TTriSurface series. I set all the parameters during the design mode but add points in the run-time. In the design mode I see right surface with random points. This example shows me right hot palette (from yellow to red). B...

Now I've tried to use TTriSurfaceSeries. But I have some problems with it (my current version of TChart Pro is 7.04) Firstly, I set UseColorRange to true, EndColor and StartColor are set automatically after choosing "Hot" from the Gallery. I have a set of points where some points have y-coordinates ...

Hi, Marjan. Hmm... You can't construct a surface cell from only two points. By definition you need four points to define surface cell (rectangle). Here are couple of rules for surface series: Thanks for the answer. I should describe my situation. Actually I've got irregular grid. It means my (x,y) p...

I've tried to use TSurfaceSeries in my application but I see it's impossible. I have some points on (x,y,height). As I understand right TSurfaceSeries use y-coordinate as a height. Ok, I add points by AddXYZ() where I send height instead of y and vice versa. It means I write the following: AddXYZ(x,...
