TChart-图表编辑器的测试

最近不知怎么的，想研究一下图表。先上效果图：

功能代码：

unit unit1;

interface

uses
  windows, messages, sysutils, variants, classes, graphics, controls, forms,
  dialogs, teeedit, extctrls, teeprocs, teengine, series, chart, stdctrls,
  comctrls;

  tform1 = class(tform)
    charteditorpanel1: tcharteditorpanel;
    charteditor1: tcharteditor;
    charteditorpanel2: tcharteditorpanel;
    chart1: tchart;

    series2: tbarseries;
    button1: tbutton;
    combobox1: tcombobox;
    label1: tlabel;

    label2: tlabel;
    procedure formcreate(sender: tobject);
    procedure button1click(sender: tobject);
    procedure combobox1change(sender: tobject);
    procedure combobox2change(sender: tobject);
    procedure chart1clickaxis(sender: tcustomchart; axis: tchartaxis;
      button: tmousebutton; shift: tshiftstate; x, y: integer);
    procedure chart1clicklegend(sender: tcustomchart; button: tmousebutton;
      shift: tshiftstate; x, y: integer);
  private
    { private declarations }
  public
    { public declarations }
  end;

var
  form1: tform1;

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;

procedure tform1.button1click(sender: tobject);
begin
  charteditor1.execute;
end;

procedure tform1.combobox1change(sender: tobject);
var
  pos: ttabposition;
begin
  pos := tptop;
  case combobox1.itemindex of
    0: pos := tptop;
    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;
  charteditorpanel1.editor.tabgeneral.pagecontrol.style := ts;
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;

procedure tform1.chart1clicklegend(sender: tcustomchart;
  button: tmousebutton; shift: tshiftstate; x, y: integer);
begin
  charteditorpanel1.editor.tablegend.show;
end;

end.
