error: TypeError: len() of unsized object when trying to plot -x FREQ -y amp -c SCAN_NUMBER with MeerKAT data
Closed this issue · 4 comments
Using the master branch shadems with the command: shadems msdir/1617605022_sdp_l0-cal.ms -x FREQ -y amp -c SCAN_NUMBER --title 'freq_vs_amp_1617605022_s
I get the error:

I had this same issue and is now solved with the deps-update branch. Please check on your side if this is also the case?
