Summary14265: Caching id algorithm does not take into account chart label options on stats
Description

If you run a stat to PDF with charts it generates PNG files for the charts using the options selected for Graph Labels.

If you rerun the stat for the survey but change the "Graph Labels" option for instance to add in the question text the image files used are the ones generated previously because the caching id algorithm does not take this change into account.

Steps To Reproduce
  1. Produce a PDF with charts using the default option.
  2. Go back and rerun the PDF with charts but this time select a different option for the charts.

The PDF will still use the old PNGs and thus the the charts will be wrong.

Additional Information

You can clear the /tmp/*.png files and it will fix it.
Possibly affects other instances where cached files are used.
Setting debug to 2 fixes but because it disables caching.

Could lead to bad errors in output.

TagsNo tags attached.
