Print multiple graphs to a PDF

[Dave C.]

Hello,

I want to print multiple selected bar charts to a PDF. To print multiple selected bar charts to a printer I use:

Code: Select all

  if PrintDialog1.Execute then
  begin
   //If only one selection, print the current bar chart
    if Tree.SelectionCount=1 then
      Graph.PrintLandscape
    else
    begin
      //For mulitple selections, get each selection, graph & print
      for i := 0 to Tree.SelectionCount-1 do
      begin
        GetItemAndGraph(Tree.Selections[i].Text);
        Graph.PrintLandscape;
      end;
  end;

where GetItemAnfGraph just gets the item and displays the graph so that it can be printed. This works great for printing, but does not work when writing to a PDF as the PDF get overwritten.

Is there a way to Append to an existing PDF or some other technique that would enable me to print multiple selected bar charts to a PDF?

Thanks!

Dave
