Hello,
I know not everybody is too pleased with itools, but i managed to create
a nice plot using iplot (for the first time)
The big problem however is: how do i save this plot. it seems that i can
only save it as .isv (which is only readable by iplot itself)
is it possible to save a plot as an eps (or other vector image)?
many thanks maarten

I just tried this. The plot shows up all right, and looks
good. But the axes annotation is missing. :-(
Is this a Ghostview problem? A preview problem? Or are they
really gone? (I don't have a PostScript printer at the moment.)
I see the annotations if I choose Bitmap output, but not if
I choose vector output.
Cheers,
David
P.S. Does this mean I have to separately annotate all my iTool
output in Adobe Illustrator to get high quality graphics? :-)

Choose the "File/Export..." menu command to bring up the IDL Data Export
wizard. At Step 1, select the "To a File" radio button and press the
"Next..." button. At Step 2, select "Window" and press "Next" (though
you may want to play with the other possibilities later). At Step 3,
choose the "File Type" you want and enter a file name, then press "Finish".
The facility to export to EPS was added in 6.1. You should upgrade to
this version if you are serious about using iTools, as the iTools system
is being developed and improved with each new version.
By default, the iTools system produces EPS files containing bitmap data.
(This is not very useful IMHO, because bitmap data data can be stored
more effectively in an image-oriented format like PNG). To change this,
choose the "File/Preferences..." menu item and select "Settings/File
Writers/Encapsulated Postscript" in the tree view. Set "Graphics format"
to "Vector". The change should affect the all iTools for the current
user. Be aware that IDL Object Graphics (on which the iTools are based)
has various limitations when producing vector output.
I've just notied that the EPS file writer dialogue also has an option to
choose bitmap or vector output. Cool!

I think you will have to loop over the points with itext.
