Modifying colours for PATTERN statement

PTD_SAS — Wed, 03 Aug 2011 06:35:55 GMT

I wonder if there is a way to automatically change the colours of pattern statement in proc gchart. E.g if the value of chart variable is negative then display the bar chart in red, otherwise in green (like traffic lights method).

Thanks.

Hi:

In this Tech Support note, they "pre-test" the values in the data to create macro variables which will be used to set the colors of the bars based on what is in each of the BY group values. So you could use a similar technique to set PATTERN statements for your scenario.

This description of how the PATTERN statement works is very useful -- you have to understand the behavior of PATTERN when a color is specified vs when a color is NOT specified and how the PATTERN statement can be "cycled":
