 Adding and removing annotations


Start the AnnotationEditorDialog and click on the- sign to remove or the + sign to add an annotation. You can add multiple annotations per series. Here is an example to remove an annotation and to add an annotation to the first series of the first pane.
procedure TForm1.AddNewAnnotation; 
var 
  ca: TChartAnnotation; 
begin 
  ca := AdvChartView.Panes[0].Series[0].Annotations.Add; 
  // set properties of the chart annotation here 
end; 

procedure TForm1.RemoveAnnotation; 
begin 
  AdvChartView.Panes[0].Series[0].Annotations[0].Free; 
end;
Note: for pane, serie and annotation adding create use the following code to set properties.
Example with annotations:
procedure TForm1.AddNewAnnotation; 
begin 
  with AdvChartView.Panes[0].Series[0].Annotations.Add do 
  begin 
    // ADD ALL CODE TO SET PROPERTIES HERE EXAMPLE: 
    Shape := asBalloon; 
  end; 
end;
There are different kinds of annotations that can be used to mark special points of interest in a series.

Balloon, Circle, RoundRectangle, Rectangle : Shapes to wrap around the text.
Line: a line drawn from top to bottom on the X-position of the point.

Offset (X, Y): the text offset from the X, Y- position of the point.
Here is a screenshot with the different shapes.

What our customers say

Finally, a chart control that hits the sweet spot! As a product, AdvChart has the right approach. It's still very simple to use, the price is perfect, the code is included and easy to modify to taste and things that would be hard to add later or by the user are already taken into account like multiple panes.

I have tried your new "TAdvGDIPChartView : GDI+ enabled multi-pane chart component" demo and I am extremely impressed. I develop applications using Borland Delphi 5 and for years now, the obvious choice for charting components has been TeeChart. Well not any more !!! I often find that charting components can be a bit clumsy and awkward to use, but your charting components' properties are extremely well laid out and easy to use. Also, when looking at the GDI plus demo, the quality of rendering and anti-aliasing is world-class. Other charting components out there advertise lovely, glossy and shiny charts on their web site, but when you run their demos it's a very different story indeed. They are often poorly rendered and produce dodgy anti-aliased drawings, they are over-priced, etc... So all in all, you certainly have the best charting component that I have ever came across - on the first release and for such a great price ! I was currently looking for a new charting component - well not any more ! I will be recommending that the company that I work for purchases your new charting component.

Thanks for a truly excellent IW component set, I am genuinely impressed. ... TMS Advanced Charts are just stunning !

- Pete Barrett via email

After using Tee Chart Pro and RiverCharts for many years it took me sometime to work through the differences with TMS Charts but - now I have worked through the learning curve the TMS Charts certainly deliver. Thanks for yet another great set of components.
