Hi,
I'm using IDL 8.3 to plot.
Everything is good but legend function fails.
The example is like this,
IDL> theory = SIN(2.0*FINDGEN(201)*!PI/25.0)*EXP(-0.02*FINDGEN(201))
IDL> observed = theory + RANDOMU(seed,201)*0.4-0.2
IDL> plot1 = PLOT(observed, 'b2', NAME='Observed')
% Loaded DLM: PNG.
IDL> plot2 = PLOT(theory, /OVERPLOT, 'r2', NAME='Theory')
IDL> leg = LEGEND(TARGET=[plot1,plot2], POSITION=[185,0.9], $
IDL> /DATA, /AUTO_TEXT_COLOR)
% Compiled module: LEGEND.
% Attempt to call undefined procedure/function: 'LEGEND'.
Any comment?
Thanks,
Haojie
