Colorbar Label Formats
QUESTION: Your cgColorbar program is great, but the labels are always integers. How can I make the labels appear as floating point numbers?
ANSWER: Use the FORMAT keyword to make the label format anything you like. To make a floating point format with two digits to the right of the decimal, you can create the color bar like this.
