Timeline charts

Would LOVE to have a timeline chart something like the following:

Ideally, you would be able to include it on the same time axis as other charts and each of the annotations would be clickable links. Would be nice to be able to associate data with the current Gantt charts as well. That way, tasks could be linked to their detail.

Hi LC,
Thanks for your suggestion. It's an interesting idea and I've added it to our wish-list to be considered for inclusion in future releases.

Hello,
I'm afraid there isn't a series to directly draw this, but it wouldn't be difficult to use the existing series to achieve a very similar result. Ie:
Code: Select all
uses CandleCh, DateUtils;
procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
tmpDate: TDateTime;
begin
Chart1.View3D:=false;
Chart1.Legend.Visible:=false;
tmpDate:=Today;
with Chart1.AddSeries(TVolumeSeries) as TVolumeSeries do
begin
Marks.Visible:=true;
XValues.DateTime:=true;
for i:=0 to 9 do
begin
AddXY(tmpDate, 10*((i mod 3)+1),'this is a long label'+sLineBreak+'with number '+IntToStr(i));
tmpDate:=IncDay(tmpDate, 3);
end;
end;
Chart1.Axes.Left.SetMinMax(0,40);
Chart1.Axes.Left.Grid.Visible:=false;
Chart1.Axes.Bottom.Grid.Visible:=false;
Chart1.Axes.Bottom.LabelStyle:=talValue;
Chart1.Axes.Bottom.LabelsAngle:=90;
Chart1.Axes.Bottom.Increment:=1;
Chart1.Axes.Bottom.MinimumOffset:=50;
Chart1.Axes.Bottom.MaximumOffset:=50;
end;
