Title‘s Colors in ChartListBox

[xsLiu]

I hope to show Titles using the same Color with its corresponding Series in a ChartListBox, but Title‘s Color is not consistent with SeriesColor in ChartListBox.

Code: Select all

  with aChartListBox do
    begin
      Chart := aChart;
      EnableChangeType := false;
      EnableChangeColor := true;
      EnableDragSeries := false;
      ShowSeriesIcon := false;
      ShowActiveCheck := true;
      ShowSeriesColor := true;
      ShowSeriesTitle := true;
      FontSeriesColor := true;
      AllowDeleteSeries := false;
      AllowAddSeries := false;
    end;

Hello,

It seems to work fine for me here:

Project1_2020-09-30_11-15-02.png (14.41 KiB) Viewed 18050 times

Code: Select all

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;
    AddSeries(TBarSeries).FillSampleValues;
    with TLineSeries(AddSeries(TLineSeries)) do
    begin
      FillSampleValues;
      Pen.Width:=2;
    end;
  end;

  with ChartListBox1 do
  begin
    Parent:=Self;
    Left:=Chart1.Width;
    Chart := Chart1;
    EnableChangeType := false;
    EnableChangeColor := true;
    EnableDragSeries := false;
    ShowSeriesIcon := false;
    ShowActiveCheck := true;
    ShowSeriesColor := true;
    ShowSeriesTitle := true;
    FontSeriesColor := true;
    AllowDeleteSeries := false;
    AllowAddSeries := false;
  end;
end;

If you still find problems with it, please arrange a simple example project we can run as-is to reproduce the problem here.
Thanks in advance.

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.

How to change the Color tag/band (between ActiveCheck and SeriesTitle) from “square” to “line”?

Please find the attached file and the hand tag.

Hello,

Depending on the series style it will be changing the Series' Pointer.Color, or just the Series' Color. Ie

Code: Select all

TBarSeries(Chart1[0]).Color:=clRed;

Code: Select all

TPoint3DSeries(Chart1[0]).Pointer.Color:=clRed;

I want to change its shape shown in the ChartListBox, not color.

Hello,

Ups.
In that case you could use a dummy TLineSeries - which symbol is drawn as a "line" when in 2D - and hide the TBarSeries - which is drawn as a "square" when in 2D - from the legend and editor. Ie:

Code: Select all

uses Series;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.View3D:=False;

  Chart1.Gradient.Visible:=False;
  Chart1.Color:=clWhite;
  Chart1.Walls.Back.Visible:=False;
  Chart1.Walls.Back.Color:=clWhite;

  with Chart1.AddSeries(TBarSeries) do
  begin
    FillSampleValues;
    ShowInLegend:=False;
    ShowInEditor:=False;
    Title:='Series1';
  end;

  //dummy series for the legend
  with Chart1.AddSeries(TLineSeries) do
  begin
    Title:=Chart1[0].Title;
    Color:=Chart1[0].Color;
  end;

  with Chart1.AddSeries(TLineSeries) do
  begin
    FillSampleValues;
    Title:='Series2';
  end;

  ChartListBox1.Chart:=Chart1;
end;
