plot function and legend in a for loop [message #91851]

Dear all,

I'm trying to create an indefinite number of lines in one plot. Additionally the goal is to additionally get a legend.

I was trying to do this somehow like this:

p=plot(spec(0), name=names(0))

for i=1,n_elements(spec-1) do p1=plot(spec(i), name=names(i), /over)

l=legend(target=[p,p1])

doing that, not unsurprisingly, I get only the first and last name in the legend.

Is there a way to mitigate the issue other than adding if statements like

if n_elements(spec) gt 2 then p3=plot ....
if n_elements(spec) gt 3 then p4=plot ....

with this way, no matter how many of these lines I add I would at some day end up with some plots not being plotted ;-)

thanks a lot and best regards
Andreas
