Forwards Chord graph no longer shows with many forwards

[mutatrum]

I have about 4000 forwards over 200 channels in the last month, and the Chord graph in the Forwards screen no longer shows. It still works when switching to 7D or 1D, but on longer timeframes it stays blank.

There is an error in the console, which I'm not sure if it's related: Error: <svg> attribute height: A negative value is not valid. ("-10")
