Hello,
Have you tried the
TLegendPaletteTool
?
Here a simple example:
Code: Select all
uses Chart, TeeSurfa, TeeLegendPalette;
var Chart1: TChart;
procedure TForm1.FormCreate(Sender: TObject);
begin
Chart1:=TChart.Create(Self);
with Chart1 do
begin
Parent:=Self;
Align:=alClient;
Color:=clWhite;
Gradient.Visible:=False;
Walls.Back.Color:=clWhite;
Walls.Back.Gradient.Visible:=False;
Legend.Hide;
View3D:=False;
MarginBottom:=10;
AddSeries(TColorGridSeries).FillSampleValues;
Draw;
with TLegendPaletteTool(Tools.Add(TLegendPaletteTool)) do
begin
Series:=Chart1[0];
Vertical:=False;
Width:=Chart1.Width;
Height:=40;
Top:=Chart1.Axes.Bottom.PosAxis+25;
Axis:=laDefault;
end;
end;
end;

Does the TLegendPaletteTool presented above exist in the javascript library?
I would like to inquire about how to implement the above example using Javascript.

Hello,
I see you asked something very similar a few months ago.

Weren't you able to make it work?
The only difference I see is in the alignment of the legend. Am I missing anything else?

I would like to contact you because the legend does not display the way
I want even if I change the position of the legend to "bottom" in the source link above.

Hello,
You could try adding a second chart at the bottom and use it to draw the legend. Ie:
