Folks
Hi,
I need to have a format like this:
.....
str='$\rho=$'+string(corr)
subtitle = text(0.24, 0.8, str, /bold,FORMAT='(F5.2)' ,font_size=12)
but it is not working in IDL. it shows like 0.64232, but i need two decimal digits.
Will u pls help?
Best,
Dave

It's because you're making your string before you apply the format code. Do it in the string() call:
IDL> a=0.64232
IDL> str=string(a,format="(f5.2)")
IDL> str
0.64
cheers,
Greg
