似乎有多種可能性,這裏是使用GetAxisLabel一種方法。對我來說,關鍵是將標籤樣式設置爲talText。
unit Unit1;
interface
uses
System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants,
FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs, FMXTee.Engine,
FMXTee.Series, FMXTee.Procs, FMXTee.Chart;
type
TForm1 = class(TForm)
Chart1: TChart;
procedure Chart1GetAxisLabel(Sender: TChartAxis; Series: TChartSeries;
ValueIndex: Integer; var LabelText: string);
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
fSeries: TPointSeries;
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.fmx}
procedure TForm1.Chart1GetAxisLabel(Sender: TChartAxis; Series: TChartSeries;
ValueIndex: Integer; var LabelText: string);
begin
if (fSeries = Series) then
begin
LabelText := IntToStr(Round(Series.YValue[ValueIndex]/1000)) + 'K';
end;
end;
procedure TForm1.FormCreate(Sender: TObject);
var
i: NativeInt;
begin
fSeries := TPointSeries.Create(self);
fSeries.ParentChart := Chart1;
for i := 1 to 10 do
begin
fSeries.Add(i * 10000);
end;
Chart1.Axes.Left.LabelStyle := talText;
end;
end.
