how to assign multiple titles on a number of plots in IDL programming language - idl-programming-language

Question

I have to assign 24 titles on 24 graphs with different values and values has a specific interval, how can I create these titles while creating multiple graphs with multiple-valued titles and how to save automatilcally these 24 graphs with different names say(1,2,3,4..) in IDL programming language
this is the structure of my code
pro prac_append
out=indgen(24)+1
ot=string(out,format='(I02.2)')
fmt='d,d,d,d,d,d,d,d,d,d,d'
cl=get_color(24,13)
for i=0, n_elements(out)-1 do begin
file=file_search('E:\ALL FORTRAN\fortran77_code\corrected\corrected_4\corrected_4\output'+ot[i]+'.txt')
readcol,file,time,x,y,z,pz,pp,phi,eta,pitchangle,ke,deta,format=fmt
p=plot(eta,deta,xtitle='eta',ytitle='dη',xstyle=1,xrange=[-7,7],yrange=[-0.8,0.6],color=cl[*,1],$
title='eta(0)='+string(i+0.27318197))
p.save,'E:\ALL FORTRAN\fortran77_code\corrected\corrected_4\corrected_4\new_plots\cor_deta\append prac\graph.png'
endfor
stop
end
thank you, your help will be appreciated

Answer 1

For saving the files to different numbered filenames:
root = 'E:\ALL FORTRAN\fortran77_code\corrected\corrected_4\corrected_4\new_plots\cor_deta\append prac'
p.save, filepath(string(i, format='(%"graph-%02d.png")'), root=root)
What do you mean by "multiple-valued titles"? Depending on what you mean, you could do something similar to the above.
