Dear List,

I have used the image() function to show a heat plot of a matrix of data whose intensity is color-coded. I have two questions that I have not been able to solve by using the help system or google.

  1. How can one add a scale/legend that shows what numerical values a given color corresponds to?
  2. How can one "flip" the rows (i.e., change the order of the rows in the image plot)?

Thanks very much in advance, Peter
