Hi,

I used plot function to create a plot. Now I want to over-plot a vertical line onto that. Can anyone tell me, how to do it?

Following is the command I used:
pp = plot(time_sec,nic_pil,xtitle='Time [sec]',ytitle='I!Dc!N/I!Dc,QS!N',dimensions=[900,800], $
yrange= [min(nic_pil)-0.01,max(nic_pil)+0.01],axis_style=1, $
MARGIN = [0.08, 0.25, 0.15, 0.15],xrange=[0.0,max(time_sec)+6])

I want to plot the line at a particular value of time_sec.

Looking forward to your suggestions:-)

Many thanks,
Anjali

hi,
try:

pl = polyline([particular_time_sec,particular_time_sec],pp.yrange ,/data,target=pp)

obviously you have to define where you want the line:
particular_time_sec = ???

Cheers,
Helder

Hi Helder,

It worked.
Thank you very much :-)
