calplot is a plotting tool for calibration tables of all types (B=bandpass, G=gain, D=instrumental polarization, P=parallactic angle, T=troposphere, M=baseline-based gain, MF=baseline-based bandpass, and K=fringe fitting). The default plot style is single-panel, but if an iteration axis is specified, multi-panel plots are supported. Zooming and region-based flagging is possible on single and multi panel plots.
