Dear Ferreters
G'day
I hope you all are doing well.
I am struggling with plotting command plot/vs for making a vertical line in the time series plot.
tohc = t[gt=ohc@asn]
plot/vs/nolab/nokey/col=1/thick/opacity=40/line/ov/dash/t=jan-1964 {`tohc`,`tohc`},{-4*10^-22,12*10^-22}
**ERROR: command syntax: plot
can anyone suggest what is wrong with this command that I am trying to plot in PyFerret v7.63.
I know that this command was working previously but now it is not and I have no idea what is wrong I am doing.
Cheers, Saurabh
