I am using TeeChart for FireMonkey (FMX) in Delphi.

What TeeChart version are you using?

Hello, You could set your TScrollPagerTool.Align to saCustom and then set the its positions manually at the same PlaceAxes method: with ScrollPagerTool.SubChartTool.Charts[0] do begin Top:=0; Left:=0; Width:=Chart1.Width; Height:=Round(Chart1.Height / ScrollPagerTool.DivisionRatio); Chart.MarginUnit...

Hello,

I've made a variant of that AutoAxes example with an improved version of the PlaceAxes function, which is now called at the OnBeforeDraw event.

Hello, In your example (https://www.steema.com/support/viewtopi ... 289#p81015) I do not understand how to calculate the values dynamically if the number of axes changes. That was a simple example to demonstrate how to place the axes to draw the series without the axes overlapping the series. Of cou...

Hello Bruce,

You could share that chart with us to see if the problem is with some chart setting itself. To do so, you can open the editor and export the chart to a tee file.

Hello, So, if one changes e.g. data of the series of the main chart, one needs to apply the changes manually to the 'corresponding' series of the scroll pager's subchart, too? Or is there an automatism in the background, that updates/synchronizes a Scrollpager's series with the one of the main chart...

Hello, Think on the ScrollPagerTool.SubChartTChart as a different TChart, with its series and axes. Indeed, there are some shorthands like ScrollPagerTool.Series to access the first series, but it's basically a SubChart. When you assign a series to ScrollPagerTool, the series is cloned into it, but ...

Hello, Is the QuickReport version 5 that works with Delphi 2007 supported? Can we use TeeChart 2024.42 with QuickReport version 5? We don't provide TeeChart binary installers for the latest versions of TeeChart for Delphi 2007, but can still use the source code version. And yes, once you have TeeCha...

Hello, There are several reporting tools that may be used to integrate TeeChart VCL: QuickReport, ReportBuilder, FastReports, DevExpress,... Feel free to investigate what reporting tool fits your needs and how do they integrate TeeChart VCL. At Steema Software we maintain and support the integration...

Hello, The main concept is that the area in which the signals (aka series) are displayed only takes up the space left by the dynamic number of axes. So, if a file has four channels, each signal in the chart has one axis. The four axes are either to the left side or the right side (or mixed eg. 2 lef...

Hello Ags,

Thanks for the explanation.
I hope we can invest more time on improving the TGLCanvas so it can be used as a 1:1 replacement to GDI/GDIPlus.
Could you please expand a little bit on the major issues? I'm not sure to understand what are you doing in the panning event.

Hello, 2) Grid The horizontal grid lines are drawn starting at the left most axis, not at the 0.0 position of the bottom axis. I do not know how to fix this! In the example project, clicking a series in the chart 'relocates' the grid to the axis of the clicked series. To see that, you need to scroll...

Hello,

Ah, I see there must be a difference between TeeChart v2024.41 and TeeChart v2024.42 where MarginToAxis got fixed.
Probably #2740 affected MarginToAxis.
Can you update to TeeChart v2024.42?

Hello,

I see the axis labels to be moving to the left every time I click a series:

Hello, I've added a scrollbar to test different Texts.MarginToAxis values and it seems to work fine for me here: mstsc_49oVHJTEMM.gif procedure TForm1.FormCreate(Sender: TObject); //...
