Charts - empty image files

[Ben]

Solved.
It appears that there were two seperate problems here.  For the old style charts, the problem really was my version of the Chart module, despite the fact that the non-date-based charts worked fine.  For the new style, the problem was a lack of understanding on my part.  I didn't realized that the method for collecting stats had changed.  
Thanks for your help Bruce and Gerv.

I'm sure the data for the charts is there, I just ran collectstats with the --regenerate option and manually checked the files.  They have data going back almost 2 years.  When doing the new charts I tried viewing just the image and adding the debug parameter onto ther URL, and here is what I got:
