Re: Drawing line between two cursors?

Hello,

It would help if you could arrange a simple example project to see what you are exactly doing.

Re: Drawing line between two cursors?

Hello, You should calculate the Interpolation points and draw the line manually. You could use the AnnotationTool to draw the difference value. Here a simple example: Dim XPos, YVal1, YVal2 As Double Private Sub Form_Load() With TChart1 .Aspect.View3D = False .Legend.Visible = False .Panel.Gradient....

Re: Show grid when no series is active

Alex,

The only way to achieve this is by adding a dummy series (with no data) as follows:

Code: Select all

  Chart1.AddSeries(TPointSeries).XValues.DateTime:=True;

Re: Quickreport installation problem

Hello,

I've replaced all the that {$IFNDEF NOUSE_BDE} for {$IFNDEF NOTEEDB} in this unit.

Code: Select all

  TQRDBChart=class({$IFNDEF NOTEEDB}TCustomDBChart{$ELSE}TCustomChart{$ENDIF})
That way, only Starter IDEs, which don't have DB, won't have access to Dataset.

Re: Title‘s Colors in ChartListBox

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.

Re: TChartSeries.CalcFirstLastVisibleIndex not quite as expected

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...

Re: Caption goes outside of bounderies

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...

Re: Show grid when no series is active

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...

Re: Installed but not in IDE

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.

Re: Quickreport installation problem

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:
