Hi there...
Is there a way to plot uncertainties in a plot.
Say you got some data:
x = {1,2,3,4}
y = {2.25,3.75,4.25,5.75}
Delta y = {0.02,0.04,0.01,0.05}
then I can plot my data as points
IDL> plot, x, y, psym=1
But is there away to get uncertainties on my data?
Thanks in advance
Martin Skou

Beisdes the standard IDL procedures already mentioned (e.g. PLOTERR,
ERRPLOT) you might want to look at PLOTERROR and OPLOTERROR in
http://idlastro.gsfc.nasa.gov/ftp/pro/plot/. These are built on the
standard PLOTERR and OPLOTERR routines but have additional options, such
as both X and Y errors, _EXTRA facility, NAN value recogntion, plotting
only every nth error bar, and the NSUM keyword.
