Multiple plot labeling

[Bob Smith <bgs@xxxxxxxxxxxxx>]

Hi Ansley,
	I was following your message to Helge regarding plot titles and
labels. I have a little script that I've been trying to do multiple plots
and have different symbols or types of lines and then print out a legend
on the plot. Not working well though. Seems like there is a multitude of
steps that have to happen to make this work or I'm not seeing the whole
picture. 
plot/set_up/nolabel/xlim=90:-90:-20/ylim=210:230:2/sym=27 temp_djf_ave 
ppl xlab @TRLATITUDE 
ppl ylab @TRDeg K 
ppl plot
plot/ov/nolabel/xlim=90:-90:-20/ylim=210:230:2/sym=33 temp_djf_ave1
plot/ov/nolabel/xlim=90:-90:-20/ylim=210:230:2/sym=21 temp_djf_ave2
plot/ov/nolabel/xlim=90:-90:-20/ylim=210:230:2/col=1 temp_djf_ave3 ! To
label/nouser 3.90,6.25,0,0,.23 @TR Zonal Ave TEMP 200 for DJF 1979t1995
label 60,215,-1,0,.20 @c7 @AC o AM2amip2 
label 60,214,-1,0,.20 @c7 @AC x AM2amip2v2 
label 60,213,-1,0,.20 @c7 @AC * AM2p10 
label 60,212,-1,0,.20 @c7 @AC - OBS
 	My hangup is in the label commands where after the @AC I have a o 
or x etc and I can't seem to get different symbols in the label command. I 
can't seem to find any examples of multiple plot output but if you have 
time to send me in the right direction I'd appreciate it.
