Hi, I'm having problems with the Performance monitor, the graph output is blank. The control port monitor is working fine.
The terminal output is the following:
ControlPort Monitor running.
ControlPort Monitor running.
gr::log :INFO: audio source - Audio sink arch: alsa
gr::log :INFO: controlport - Apache Thrift: -h Precision-7820-Tower -p 34612

i = nearby.index(min(nearby))
ValueError: min() arg is an empty sequence
The error only occurs when I click somewhere in the window of the performance monitor.
