Charts appear in black and white (or only 4 colors)?
Solution 1 : We use a third party graphing utility that seems to have some problems creating charts on some Windows systems using a 32 bit color resolution. The only solution for this problem has been to reduce the color resolution for the server so that it creates valid charts for the end users. Solution 2 : On some systems, switching to a JRE 1.5+ may solve the problem. See details in previous question.
