How do you associate data with a secondary Y axis? 1296 1
Started by Deleted User
Hello,
I understand how to use the AXIS function in IDL 8.1 to create a second X or Y axis on a plot, but how do you link the data so that it corresponds to the second axis For example, if DATA1 has a range of 0 to 10, but DATA2 has a range from 1,000 to 30,000 and how can you add the second axis so that each dataset can be properly plotted on the same figure I recall that in when using the AXIS procedure, you could use the /SAVE keyword to set the axis system variable, but I don't see a ...

switch to IDL 8: no more F1 help shortcut, and other issues 1073 2
Started by Deleted User
I have just performed the switch to IDL 8, using MacOS X 10.6.8 Snow Leopard. Many new features, many language improvements, it has been tempting to switch for a long time now...
A significant software upgrade usually doesn't come without some hassle, and so does IDL 8.
For now the most annoying thing is the apparent impossibility to get online help on the command at the cursor by simply pressing F1. I've tried almost everything:
- moving the cursor to the position and selecting the comma...

I am a IDL programmer begginer.
I would apply all textural filters from ENVI on a big and high resoluted satellite images.
My images are masked images so they countain lots of "0" values.

Could you give me some clues to develop this tool effectively
Best regards.

Compilation Error: Procedure header must appear first and only once 2812 2
Started by Deleted User
I've been trying to get someone else's program written in IDL 6.4 to compile in IDL 8.0. I don't have any previous experience with the language, and my C/Python experience is proving a poor substitute to expert knowledge. I'm running into the most curious compiler error in two of my files. I can't put the full code up here (to begin, between the two there are probably 3000 lines), but I'll try to describe things as best I can. It's fairly simple: in both of the files, all the procedures and func...

Using an array (instead of fid=fid) in IDL to run TOPO_DOIT 1054 0
Started by Deleted User
Dear all,
I searched the forum, google, and the help files but couldn't find an answer. I have two brief questions; I would appreciate if you could answer them.
Q1) I want to use a variable of my own inside idl to run TOPO_DOIT.. Briefly instead of saying:
ENVI_DOIT, 'TOPO_DOIT', fid=fid, elevation= 45.00, azimuth=110.00, BPTR = &912&93, DIMS = dims, POS = &910&93, R_FID = r_dif, PIXEL_SIZE = pixel_size, IN_MEMORY = 1
I want to use

I need some suggestions on navigating an image in IDL - kind of transformation of pixel coordinates in byte arrays to Actual planetary coordinates - In other words, Georeferencing.

Composite images 1208 0
Started by Deleted User
Hello,
I am trying to place multiple images created using the IMAGE function in the same figure using the new IDL 8.1 graphics functions. I know that you can initially create a window and then add each image using specified positions or layout, but I was wondering if you can first create two images &91i.e. i1=image() and i2=image()&93 and then merge them onto a new window afterwards. By creating the images first, I do not run into positioning issues when adding text and colorbars to the indi...

IDL 8.1 Map() Latitude labels - Label_Position bug? 1096 0

I've found that when I plot using the MAP() function in IDL 8.1, in this case a Cylindrical projection using limits = &91-180, -35, 180, 35&93, that I cannot get the latitude labels to be positioned to the left of the map when center_longitude=180. When the map function's label_position=0, the latitude labels are positioned at 180 degrees (middle of the map). When label_position=1, the latitude labels are positioned to the right of the map. I cannot get the labels to move any farther to the...
