lineseries and legend

[JimR]

How should a lineseries with no markers be displayed in the legend? I get markers when they are visible in the chart. However I would like a short line with the same color as the line in the chart when no markers are displayed. Ideal would be to have both lines and markers shown in the legend if both are visible in the chart. Suggestions?

Hello Jim,

The legend shows line+pointer or only the line when applies for me here:

Am I misunderstanding anything?

Your example is what I want. Is there some option I need to set?

Hello,

I only created two TLineSeries, and made the Pointer one of them visible and smaller (to see its line better):

Code: Select all

uses Series;

procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
begin
  Chart1.View3D:=False;

  for i:=0 to 1 do
    with Chart1.AddSeries(TLineSeries) as TLineSeries do
    begin
      if i=0 then
      begin
        Pointer.Visible:=True;
        Pointer.Size:=2;
      end;

      FillSampleValues;
    end;
end;

Another option is to make the legend symbol not squared and wider:

Code: Select all

uses Series;

procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
begin
  Chart1.View3D:=False;

  for i:=0 to 1 do
    with Chart1.AddSeries(TLineSeries) as TLineSeries do
    begin
      if i=0 then
        Pointer.Visible:=True;

      FillSampleValues;
    end;

  Chart1.Legend.Symbol.Squared:=False;
  Chart1.Legend.Symbol.WidthUnits:=lcsPixels;
  Chart1.Legend.Symbol.Width:=25;
end;

I must have some wrong settings. I now do get lines and the symbols in the legend. The symbols are the correct colors but the lines are all black.

Hello,

The symbols are the correct colors but the lines are all black.

Does it happen with the latest version (v2017.22) and the examples above?

[JimR]

Yes, that is the version I am using.

[Yeray]

Hello,

Yes, that is the version I am using.

And do you get a different running the same code in the examples above?
