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?

• 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?
