Summary14426: Error exporting PDF with graphs
Description

When I export the statistics of a survey to a PDF it works like a charm, but if I enable the option "Show graphs" and try to export it, I get the following error:

"count(): Parameter must be an array or an object that implements Countable"

Additional Information

I am attaching the html page with the error.

TagsNo tags attached.

@LouisGac: I didn't fixed this bug.
I can't reproduce it with error message, but I can see that graph silently fails to load in pdf or Excel file.
So I would try to fix it.

The error does not appear if I turn off the debug mode as it is said in https://bugs.limesurvey.org/view.php?id=14417

I guess this happens cause it is a warning so if debug mode is turned off it does not show anything.
