I have three charts rendering correctly and I would like to provide the user with a button they can press to generate a PDF copy of the current view. I understand a way to do this is to export the three charts to images, save the images in a folder on the server then embed these into a PDF using a third party PDF library. I have been able to do this and it seems to work however I get three separate JS CallBacks using 'FC_Exported'.
I have noticed that if I use the batch export mode, all charts export fine but I then have to click the 'Save All' button to save them into a single image file. A single image file is easier for me to handle. So two questions....
1. Is there a way to get a single JS Call Back when all three chart images are exported?
2. Is it possible to have all chart images saved into a single server side file without having to press two buttons?
Thanks in advance.
