Pie chart off two Edit fields 1

[ukusa]

Well, I'm stumped as I haven't played around with charts in Delphi before. In my Import and Export Records funtion, I have two edit fields not adjoined to a table giving the Rejected and used counts. I don't want to use a table to record the values, is there any way I can just read the values on the form itself where the chart is and from those fields and have the Pie chart read them directly?

Thanks

Delphi provides a component called TChart (found in the 'Additional' components tab). You can just drop this on the form where you wanna see the graph. Double-click on the placed component to access the Chart Editor (which gives you a host of options). You'll need to add a series, selecting pie chart as the appropriate graph. Drop a button on the form, and in its' OnClick event write some code to populate the graph. Something like this should work (1st parameter is your numerical value, 2nd parameter is a label for that value):

with Series1 do
begin
  Add(Rejected_Number, 'Rejected');
  Add(Used_Number , 'Used');
end;

Hope this helps!
Happy charting! ;-)
