Using Visualization with HTML to PDF

[Jason Peter]

Hi there - I have a page that I've used for quite  a long time with good success.  It has some pie charts.  I am trying now to run through a data set in my SQL Server db that has about 3000 records and have a program render the page then export to PDF.  I have that all working as  intended but a good portion of the time the graphs do not show on the pdf even though when viewed in the browser for that particular page and that record it shows fine.  I'm wondering if the image is sometimes not able to be rendered quickly enough or perhaps google is blocking the request since there may be too many.  I've tried sleeping the process for 250 ms and even 5000 ms and it still sometimes does not work - most times in fact.  Any ideas on how I can remedy this?
