【问题描述】:
我有条形系列,我想在其中设置包含系列标题和条形实际值的标记样式。这是我的代码:
procedure TFRDept.PopulateDeptChart;
var
Loop ,YearIndex: integer;
DeptKey: String;
StartBar, TotalBar, EndBar : TBarSeries;
begin
for Loop := 0 to FDeptList.Count -1 do
begin
DeptKey := FDeptList.ValueFromIndex[Loop];
StartBar := GetInsertedBarSeries(DeptKey+'Start', 'Start', clGreen);
TotalBar := GetInsertedBarSeries(DeptKey+'Total', 'Total', clBlue);
EndBar := GetInsertedBarSeries(DeptKey+'End', 'End', clRed);
with Dataset do
begin
if Locate('o_deptaddressno',DeptKey,[]) then
begin
While (FieldByName('o_deptaddressno').AsString = DeptKey) and not eof do
begin
StartBar.AddXY(FieldByName('o_year').AsInteger,
FieldByName('o_totalstart').AsInteger,
FieldByName('o_year').AsString,
StartBar.Color);
{when adding series per year for each department - the bars are not one after the other}
//TotalBar := GetInsertedBarSeries(DeptKey+'Total'+FieldByName('o_year').AsString, siLang.GetTextOrDefault('IDS_TOTAL'), clBlue);
TotalBar.AddXY(FieldByName('o_year').AsInteger,
FieldByName('o_total').AsInteger,
FieldByName('o_year').AsString,
TotalBar.Color);
TotalBar.Title := FieldByName('o_total').AsString + ': '+ FDeptList.Names[Loop];
TotalBar.Marks.Style := smsSeriesTitle;
TotalBar.Marks.ArrowLength := 50;
TotalBar.Marks.Callout.ArrowHead := ahSolid;
EndBar.AddXY(FieldByName('o_year').AsInteger,
FieldByName('o_totalEnd').AsInteger,
FieldByName('o_year').AsString,
EndBar.Color);
Next;
end;
end;
end;
end;
SetSeriesLegendProperties;
end;
function TFRDept.GetInsertedBarSeries(aName, aTitle: String;
aColor: TColor): TBarSeries;
begin
Result := TBarSeries.Create(Self);
with Result do
begin
Name := 'Series' + aName;
Title := aTitle;
Color := aColor;
Marks.Style := smsValue;
end;
Chart1.AddSeries(Result);
end;
我的代码生成以下条,但蓝色条的值未在标记中获得适当的值。
实际上,我的目标是在每个系列的条(红色、绿色和蓝色)上方显示各自的部门。我什至选择了另一种方法,尝试使用“绘制符号”修改图例,但事件没有触发。是否有可能在带有复选框的样式 lsSeriesGroups 的图例中显示符号?然后我也可以设置 Totalbar :
Marks.Symbol.Visible := True;
