I recently re-initialized by QNAP NAS and had to re-install wfrog (it was previously running fine). Ran into 2 issues.
1) My Optware repository didn't contain pygooglechart anymore. Checked possible mirrors and still no luck. I had to install pygooglechart manually by downloading from its home site and issuing "python setup.py install".
2) Managed to get wfrog running now but the chart output is really weird. There is an extra line in the line charts which goes from the bottom left of the axes (I hesitate to call it the origin since it's not 0,0) to the top right. You can view it here at http://treasures.myqnapcloud.com/wfrog/3hours.html
Anyone have some advice on how to remove the extra line from the plots? Thanks!
