Board index » delphi » Labels on TeeChart XY points only

Using a TeeChart point graph, how do I put labels on the points in the chart
without the labels appearing on the X-axis?
My code looks like this
for i:=0 to 100 do
Series1.AddXY(X[i],Y[i],Labels[i]);
The Labels[i] appear in the correct coordinate spot (X[i],Y[i]) in the
chart; but they also appear on the abcissa position on the x-axis. I just
want the x-axis without the labels on it.
How do I do that?
Thank you very much in advance.

Hi JS,
For hidding the axis labels you have to disable them and make series marks
visible to show the labels at the X,Y point:
Chart1.BottomAxis.Labels:=false;
Series1.Marks.Visible:=true;
You can also implement the Series OnGetMarkText event to customize the marks
contents.

Thanks for the reply! All I want to do is have a plain XY scatterplot,
where the points are given by (x,y) coordinates, a label is put on each
point to identify it, and the axes of the scatterplot just have a regular
numerical scale. How do I do that?
For example, the x-axis ranges from 50 to 100 (in kilograms), the y-axis
from 140 to 210 (in centimeters), and the points have initials of
individuals. The initials appear on their respective points on the graph,
not anywhere on the axes. Thus one can examine the axes to determine the
x,y coordinates of the points.
Thanks again,
JS

Hi JS,
According to the example you suggested you can do something like:
procedure TForm1.FormCreate(Sender: TObject);
begin
With Series1 do
begin
AddXY(70,175,'JP',clTeeColor);
AddXY(60,155,'IG',clTeeColor);
AddXY(98,190,'XR',clTeeColor);
AddXY(58,172,'BS',clTeeColor);
AddXY(63,166,'JM',clTeeColor);
Marks.Visible:=true;
end;
With Chart1.BottomAxis do
begin
SetMinMax(50,100);
LabelStyle:=talValue;
Increment:=5;
Title.Caption:='Weight (Kgs.)';
end;
With Chart1.LeftAxis do
begin
SetMinMax(140,210);
Title.Caption:='Height (Cms.)';
end;
end;
