Hi, I'm trying to create a basic Open High Low Close chart using
TAChart, but I'm getting a RunError(201) on tacustomsource.pas line
433, aparently YList is not initialized.
Here's the lfm:
object Form1: TForm1
Left = 364
Height = 354
Top = 255
Width = 582
Caption = 'Form1'
ClientHeight = 354
ClientWidth = 582
OnShow = FormShow
LCLVersion = '1.3'
object Chart1: TChart
Left = 0
Height = 354
Top = 0
Width = 582
AxisList =
item
Minors =
Title.LabelFont.Orientation = 900
end
item
Alignment = calBottom
Minors =
end
Foot.Brush.Color = clBtnFace
Foot.Font.Color = clBlue
Title.Brush.Color = clBtnFace
Title.Font.Color = clBlue
Title.Text.Strings = (
'TAChart'
)
Align = alClient
ParentColor = False
object Chart1OpenHighLowCloseSeries1: TOpenHighLowCloseSeries
end
end
end
And Here's the .pas
unit Unit1;
{$mode objfpc}{$H+}
interface
uses
Classes, SysUtils, FileUtil, TAGraph, TASources, TAIntervalSources,
TAMultiSeries, Forms, Controls, Graphics, Dialogs,
StrUtils, DateUtils, TACustomSeries;
type
{ TForm1 }
TForm1 = class(TForm)
Chart1: TChart;
Chart1OpenHighLowCloseSeries1: TOpenHighLowCloseSeries;
procedure FormShow(Sender: TObject);
private
{ private declarations }
public
{ public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.lfm}
{ TForm1 }
procedure TForm1.FormShow(Sender: TObject);
var
lCSV: TStringList;
lLine: TStringList;
I: Integer;
lDate: TDate;
lOpen: double;
lHigh: double;
lLow: double;
lClose: double;
lStr: string;
begin
lCSV := TStringList.Create;
lLine := TStringList.Create;
DefaultFormatSettings.DateSeparator:='-';
DefaultFormatSettings.ShortDateFormat:='D-MMM-Y';
DefaultFormatSettings.ShortMonthNames[1] := 'Jan';
DefaultFormatSettings.ShortMonthNames[2] := 'Feb';
DefaultFormatSettings.ShortMonthNames[3] := 'Mar';
DefaultFormatSettings.ShortMonthNames[4] := 'Apr';
DefaultFormatSettings.ShortMonthNames[5] := 'May';
DefaultFormatSettings.ShortMonthNames[6] := 'Jun';
DefaultFormatSettings.ShortMonthNames[7] := 'Jul';
DefaultFormatSettings.ShortMonthNames[8] := 'Aug';
DefaultFormatSettings.ShortMonthNames[9] := 'Sep';
DefaultFormatSettings.ShortMonthNames[10] := 'Oct';
DefaultFormatSettings.ShortMonthNames[11] := 'Nov';
DefaultFormatSettings.ShortMonthNames[12] := 'Dec';
try
lCSV.LoadFromFile('aapl.csv');
for I := 0 to lCSV.Count - 1 do
begin
if I = 0 then
continue;
lLine.CommaText:= lCSV[I];
lDate := ScanDateTime('d-mmm-y', lLine[0]);
lOpen := StrToFloat(lLine[1]);
lHigh := StrToFloat(lLine[2]);
lLow := StrToFloat(lLine[3]);
lClose := StrToFloat(lLine[4]);
Chart1OpenHighLowCloseSeries1.AddXOHLC(I, lOpen, lHigh, lLow,
lClose, DateToStr(lDate));
end;
finally
lLine.Free;
lCSV.Free;
end;
end;
end.
Also I attached the file aapl.csv I'm using to feed the data.
