Simple steps to create Delphi chart

Simple steps to create Delphi chart

Use following simple steps to start your first chart using Delphi TChart component:

• Put chart component on the form
• Double click on chart, then you will see chart editing dialog box.
• Click add button in series tab sheet.
• Select the chart style from the list (Line, Bar, Pie ..)

Put following code to add data into the chart

procedure TForm1.Button1Click(Sender: TObject);
begin
    { function AddXY(Const AXValue, AYValue: Double;
    Const AXLabel: String; AColor: TColor) : Longint;
    
    This function inserts a new point in the Series.
    The new point has X and Y values. The AXLabel
    parameter is optional (can be empty ''). The AColor
    parameter is optional (can be clTeeColor).
    The function returns the new point position in the
    Values list. }
    Chart1.Series[0].AddXY(10, 20, '', clTeeColor);
    Chart1.Series[0].AddXY(15, 50, '', clTeeColor);
    Chart1.Series[0].AddXY(20, 30, '', clTeeColor);
    Chart1.Series[0].AddXY(25, 70, '', clTeeColor);
    Chart1.Series[0].AddXY(30, 10, '', clTeeColor);
    Chart1.Series[0].AddXY(35, 50, '', clTeeColor);
    Chart1.Series[0].AddXY(40, 45, '', clTeeColor);
    Chart1.Series[0].AddXY(45, 10, '', clTeeColor);
    
    { Or you can write following code using "With" statement.
    Its much easier than repeating everything again and again.
    
        With Chart1.Series[0] Do
        Begin
            AddXY(10, 20, '', clTeeColor);
            AddXY(15, 50, '', clTeeColor);
            AddXY(20, 30, '', clTeeColor);
            AddXY(25, 70, '', clTeeColor);
            AddXY(30, 10, '', clTeeColor);
            AddXY(35, 50, '', clTeeColor);
            AddXY(40, 45, '', clTeeColor);
            AddXY(45, 10, '', clTeeColor);
        End;
    }
end;
