Coyote Graphics Plot Gallery
Coyote is offering a free on-line course entitled
Installing and Using the Coyote Graphics System on Thursday, March 13th. See the
above announcement for details.
This is a gallery of example IDL programs and graphics plots, written using
Coyote Graphics routines. Its
purpose is to demonstrate the best programming practices for creating direct graphics graphical
output in IDL. Click any image to see a larger representation of the graphical output. You will
install the Coyote Library to run these programs successfully.
Each example program consists of an IDL procedure that will create the graphical output in an IDL graphics
window. Following each program is a main-level IDL program that will run the example program and display
the graphical output in both a normal IDL graphics window and in a resizeable graphics window. In addition,
the main-level IDL program will create both a PostScript file and a PNG file of the graphical output.
PNG file output requires that ImageMagick
is installed properly on your machine. If this is not the case,
simply remove or comment out the last line in the main-level program before running the program.
If these programs don't run as you think they should, please
follow these steps to resolve
the problem. You will need a version of the
that was created
on or after 14 January 2014 to run all the programs in the gallery.
Disclaimer for Function Graphics Code: For the most part
the function graphics code available on this page was made available to me by Matthew
Argall. I run the code (when possible) in IDL 8.2.3 and post the results. Your results
may differ from mine. I don't know what to tell you. I have a hard time, occasionally, getting
these programs to run correctly. For example, I just spent one and a half hours trying to
get Matthew's basic contour plot to display correctly on my machine and the contour labels were
still upside down. Later, we figured out how to right them. So, I'm just saying, use these function graphics routines
at your own risk. If you find a better way of doing things, we would love to hear it.
