    最近不知怎么的,想研究一下图表。先上效果图:

    功能代码:

    implementation
    
    {$R *.dfm}
    
    procedure TForm1.FormCreate(Sender: TObject);
    begin
      Self.Position := poScreenCenter;
      //右下角图表编辑器树形显示
      ChartEditorPanel2.Editor.Tree.Visible := True;
      //随机添加10个数
      Series1.FillSampleValues(10);
      Series2.FillSampleValues(10);
    end;

        1: Pos := tpBottom;
        2: Pos := tpLeft;
        3: Pos := tpRight;
      end;
      ChartEditorPanel1.Editor.TabGeneral.PageControl.TabPosition := Pos;
    end;
    
    procedure TForm1.ComboBox2Change(Sender: TObject);
    var
      ts: TTabStyle;
    begin
      ts := tsTabs;
      case ComboBox2.ItemIndex of
        0: ts := tsTabs;
        1: ts := tsButtons;
        2: ts := tsFlatButtons;
      end;

    end;
    
    procedure TForm1.Chart1ClickAxis(Sender: TCustomChart; Axis: TChartAxis;
      Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
    begin
      ChartEditorPanel1.Editor.TabAxis.Show;
      ChartEditorPanel1.Editor.TabAxis.PageControl.ActivePage.PageIndex;
    end;

    begin
      ChartEditorPanel1.Editor.TabLegend.Show;
