										Hello everyone,
I encountered a problem regarding different behavior of the IDL runtime versus the IDL development environment. This problem can be best explained using the following example code:
pro test_iplot
iplot, indgen(10)
res = dialog_message( 'Back from iPlot', /INFORMATION )
end
When I create an executable (.sav file) from this routine and run it within idlde, iplot is started and after this has been initialized, the dialog_message statement is executed. When I start the ...

The example of ROI in Data Analysis of IDL Demo is appealing.  This is a wonderful example that I hope to use in my work.  Did this code come with the whole IDL package  Can you please tell me where it can be found  Thanks.  -- Yongsheng

										I'm creating a hemispherical model using object graphics that is capable of being rotated, translated, zoomed, etc.  When the window dimensions are square, the hemisphere is spherically shaped.  I want the final aspect ratio to be 4:3 - when I implement this, the hemisphere becomes squashed.  I tried to scale the model in the x-direction to look square again, but then the problem is that the trackball rotation from bottom left to top right makes changes the model from spherical to footballish.  ...

										Hi 
I am doing some Principal Component Analysis with PCOMP.  I haven't found the on-line help of much use. 
Probably because they seem to use a strange nomenclature than that I am used to in PCA.
Does anybody have any links to tutorials or similar where PCOMP has been used and explained in more detail than the online help
Thanks

										Hi there
I'm having trouble opening a dataset in IDL5.6 and IDL6.0. IDL recognizes the file as HDF5 (H5F_IS_HDF5), successfully opens the file (H5F_OPEN), and even gives me the correct information about the datasets in the root group (H5G_GET_NMEMBERS, H5G_GET_MEMBER_NAME). However,  opening a dataset in this file (H5D_OPEN) fails, with this error message:
 H5D_OPEN: dataset not found: (67108864, 'Density')
I suspect the problem is due to incompatible versions of HDF5. IDL's library (i...

										Using iTools for batch processing  2423  1

										I am looking for a way for using the iTools for non-interactive (batch) proccesing. The idea is to use for example iPlot in batch mode to produce a plot, save it both as an image (e.g. jpeg)as well as in *.isv format. If needed a user can later costumize the plot by running iPlot in the interactive mode and openening the *.isv file.
Another application is to use iPlot to create an iPlot in a specific layout and save it to *.isv file. Later the batch mode may be used to add or modify the data, r...
