Updating Chart at runtime
When updating the chart component at runtime it is important to "tell" the chart to update itself.
Whenever you change properties, or add/remove points the chart will not be updated.
This is because the chart will be repainted over and over again every time you change a property.
This would cause a slow performance.
To update the chart at runtime, after you change properties, you must use the BeginUpdate / EndUpdate methods.
Sample: Updating a series of points at runtime
procedure TForm1.Button1Click(Sender: TObject);
begin
AdvChartView1.BeginUpdate;
with AdvChartView1.Panes[0].Series[0] do
begin
Points[0].SingleValue := 100;
Points[1].SingleValue := 50;
Points[2].SingleValue := 20;
Points[3].SingleValue := 30;
Points[4].SingleValue := 150;
Points[5].SingleValue := 160;
end;
AdvChartView1.EndUpdate;
end;
