gnuplot not working under ISISV5

[Ken Harrison]

I've installed gnuplot (hopefully correctly!) and pointed ISIS to the gnu folder...
When I try to plot a calibrated profile (as per the Tut example) - nothing appears...I get the message that a .png file has been written to my working directory...but's there's nothing there!!
What am I missing??

[Ken Harrison]

Hmmm
That's interesting...
If I import the ISIS profile into Vspec and call up gnuplot - the gnuplot screen comes up, with the correct file names etc - and it plots the profile graph OK!!!!
(After ISIS I looked at the gnu.txt file it seems to be calling up the @.fit file to plot????)

Hi Ken,

did you install the new plot routines for V5 from here:
http://www.astrosurf.com/buil/isis/gnuplot/install.htm
Maybe you have still installed the routines for V4 of ISI, which do not work any more.

Regards,

Martin

Martin,
yes I downloaded gnuplot V4.6 and the files listed... still no success under ISIS

I've reinstalled but still the same error:
This is gnu.txt:
cd 'c:\\program files (x86)\\isis\\star analyser tutorial\\'
call 'c:\\program files (x86)\\gnuplot\\std.gnu' 'c:\\program files (x86)\\isis\\star analyser tutorial\\@.dat' 'alpha_trial3' '4000:6800' '0:3' '640, 480' '.png'
pause -1

The "@.dat" doesn't look right??

Hello Ken,

I think we had this problem before. It looks like you have installed gnuplot in ..\program files\..:
call 'c:\\program files (x86)\\gnuplot\\std.gnu'
______________.^
ISIS does not like the spaces in directory names. Try installing Gnuplot directly in C:\ or in a folder not containing any spaces.
Maybe also the directory
c:\\program files (x86)\\isis\\star analyser tutorial\_
__________.^_________________^
makes a problem. Change it accordingly. Hope this get you on the right track.

Martin,
Thanks for the help. That worked!
Just moved the working and gnuplot folders to c:\
Much appreciated!
