Scheduled Reports missing charts

Scheduled Reports missing charts

I've scheduled a report in my Zoho Desk application.  While looking at the report from a browser, it has the  chart at the top and the supporting data underneath it.

When I schedule the report and email it as a PDF, the report is missing the chart at the top.  See the 2 pics below for an example.

Any thoughts on how to get the bar charts to be included in the PDF?
