- How do I change plot parameters in cgWindow?
- How do I add a legend to a CGS graphics window in IDL?
- How do I use run-time evaluated keywords and parameters in a cgWindow resizeable graphics window?
- Why do Greek characters not show up in cgWindow PostScript output?
- Why are TexToIDL characters incorrect in cgWindow PostScript output?
- Why are symbols sometimes incorrect in cgWindow?
Colorbar Display Tips
- How can I leave room for colorbars when I display multiple images with cgImage?
- How do I display a colorbar with a log-scaled image?
- How do I add a color bar to my graphics plot?
- How can I annotate cgColorbar with my own labels?
- Your nice cgColorbar program won't display my colors. Why not?
- Can you show me how to display an image with a logarithmic color bar?
- When I use your cgColorbar program how come there is a dark line in the color table representation?
- How can I build a discrete color bar with the labels centered on the colors?
- How do I make cgColorbar to use floating point labels?
Legends and Symbols
- How do I add a legend to a graphics window?
- Why does the NASA AL_Legend command display incorrect colors?
- How can I create a greater-than-or-equal-to symbol?
- How can I create a less-than-or-equal-to symbol?
- How can I create a degree symbol?
- How can I create a not-equal-to symbol?
- How can I create a prime symbol?
- How can I create an Angstrom sign?
- Why are symbols sometimes incorrect in cgWindow?
File Output
- How do I create PDF files using Coyote Graphics?
- Create PostScript, PDF, and raster files from basic Coyote Graphics commands!
- How does Coyote Graphics output compare with Function Graphics output?
Map Projections and Data
- New Coyote Graphics map projection routines are now available!
- How can I open a GeoTIFF image and have it automatically be georegistered?
- How can I use my own political boundary database (shapefiles) on map projections?
- Are there better options for continental outlines on maps than the built-in database?
- Can you show me how to draw a map with a day/night terminator shown?
- Yikes! Map_Grid doesn't clip map labels if I use hardware or true-type fonts!
- Why can't I set a latitude of true scale in my polar stereographic map projection?
- The UTM map projection produces incorrect results with WGS84 datum.
- Silent substitution affects map projection results.
- Where do the extraneous lines in Map_Grid come from?
- Does Map_Proj_Init calculate incorrect UV ranges?
- Can you show me how to navigate a GOES
East or West GeoTiff image?
- Compare filled contour plots in different
graphics systems.
Miscellaneous Tips
- Yikes! What happened to TVImage, FSC_Color, and FSC_Colorbar? Have these programs been renamed?
- How can I make Coyote Graphics routines find ImageMagick on my Mac?
- How can I create a graphics window with a white background?
