Hi,

After some time, the graphs will throw a HTTP 500 and the following entry will show up in the docker logs:

"plotscript" line 120: undefined variable: i

Huh. That should only happen if you're seeing speeds in excess of 5 Gbit/s or have your MARKER_DOWNLOAD set to something bigger than 4166. I'm seeing a maximum speed of about 4 Gbit/s (Maximum: 4.05545e+09) in your log, so I'm guessing you set the marker ...

I guess I never expected anyone with more than a Gigabit to use this script. :P The fix should be easy, though ..

The first attempt was a little broken when used with an UPLOAD_SCALE, which I did not notice in my local testing:

Commit 80a1233eb93ee56020a9769841da88469f937940 should fix that, though. Give it a moment to build a new image and re-pull.

Thank you so much for looking into it! I'll give it a test now. No markers were setduring my report.
