Hello,

I've replaced all the that {$IFNDEF NOUSE_BDE} for {$IFNDEF NOTEEDB} in this unit. That way, only Starter IDEs, which don't have DB, won't have access to Dataset.

Hello,

You are setting the series LinePen.Color, which is ok for the lines connecting the 3d points, but you should set the main series' Color.

Hello Toreba, The issue is that you are calculating the first and last visible values in the series when the axis hasn't been yet recalculated. That's why this can be solved forcing a chart repaint Self.chtFastLine.Draw; or simply a bottom axis recalculation Self.chtFastLine.Axes.Bottom.AdjustMaxMin...

Hello, It seems to work fine for me here: Project1_2020-09-30_11-15-02.png procedure TForm1.FormCreate(Sender: TObject); var Chart1: TChart; ChartListBox1: TChartListBox; begin Chart1:=TChart.Create(Self); ChartListBox1:=TChartListBox.Create(Self); with Chart1 do begin Parent:=Self; View3D:=False; A...

Hello, You could wrap the text to fit the length you wish. In this case you may want to use ChartRect.Height . Ie: procedure TForm1.WrapLeftAxisTitle(aChart: TChart; const aHeight: Integer); var lOneLineTitle: String; lTitleHeight: Integer; lTitle: TChartAxisTitle; lHeight: Integer; begin Assert(aCh...

Hello Alex, TeeChart doesn't draw an axis when no series uses it and LabelStyle is set to its default value: talAuto . Also, you may want to set some min and max. Ie: Chart1.Axes.Bottom.SetMinMax(0,10); Chart1.Axes.Bottom.LabelStyle:=talValue; Chart1.Axes.Left.SetMinMax(0,10); Chart1.Axes.Left.Label...

Hello Teri,

Try to add the design time package (DclTeePro927.bpl) from the "Delphi27\Delphi27.win32\Bin" folder in your TeeChart installation into the "Components/Install packages" list.

Hello,

The TQRChart packages you are using may be referencing the DclTee (Standard) package instead of the DclTeePro package.
Find here the packages precompiled for RAD Tokyo 10.2.3, QuickReport 6 and TeeChart Pro v2020.30:

Hello,

I don't seem to remember experiencing an issue like that. If you can arrange a simple example project we can run as-is to reproduce the situation here I'll be glad to test it.
Thanks in advance.

Hello, Sorry for the delay here. You could create a new method (ie WrapLeftAxisTitle ) and move the code from the OnResize event to it. Then, you only have to add a few parameters to it and call it both at OnResize event and in your AssignChartToGraphic method. Ie: Axis Caption with Image.zip

Hello,

You are right, Chart1.Draw isn't enough with this kind of series because this series min and max doesn't correspond to the y values min and max. It needs Series1.RecalcStats to be called instead.

Hello,

1. The Callout does not draw a line from THE ANNOTATION.

I've reproduced it so I've added it to the public tracker:

2. Axis’s Titles are not in the right positions and angles.

Take a look at the discussion and code here.

Hello, Calling SetMinMax is usually enough to reflect the changes immediatelly. If it doesn't it may be because some other setting in the chart is impeding it. Do you have AutoRepaint set to false? If you still find problems with it, please arrange a simple example project we can run as-is to reprod...

That depends on how are you drawing the polygons. If you are drawing them at a series' OnGetPointerStyle event as in the example I linked above, disabling the series should be enough to stop calling that event and thus your custom drawing code.

Hello, Transparency is applied with Blending: uses TeCanvas; //... var tmpBlend : TTeeBlend; const transp=80; begin //Prepare Pen and Brush if transp>0 then tmpBlend:=Chart1.Canvas.BeginBlending(TeeZeroRect,transp); //Draw polygon if transp>0 then Chart1.Canvas.EndBlending(tmpBlend);
