At least in windows, it works:

I will try to test it under Linux later.
McGiverGim commentedon May 6, 2019
Tested under linux:
Graph setup
button, and all ok.Maybe some old data of older versions, that is refreshed in the Graph setup. Can you test to add some graphs?
flatwound commentedon May 6, 2019

I've never installed or run the black box explorer before today, and ran into this issue. v3.3.1 win32 on Win 10

Maybe this is a fixable issue? ;(

Same issue here on Win10, BBLV version 3.4.0 win32

Same issue here on Win 10, version 3.5.0 from
betaflight-blackbox-explorer-installer_3.5.0_win32.exe

Same issue here on a fresh Win10 system. After pressing 'Graph setup' and 'Save changes' the graph suddenly appeared.
McGiverGim commentedon Jun 23, 2020
We usually associated this to an update of the blackbox. Your windows 10 never had blackbox installed before?
dkijkuit commentedon Jun 23, 2020
No I actually used the blackbox for the first time ever ;)
Also the legend for the motors showed 'ZNaN' and 'ENaN' which indicates something went wrong (assuming this refers to 'Not a Number').

I can confirm the issue. Same here. First time opening on Windows and had to follow the steps described above to get my graphs going.
McGiverGim commentedon Jul 3, 2020
I reopen this issue. Needs to be investigated.

same issue here under linux and V3.5
