License: Free for non-commercial use Changes:
An option to specify the window target for CSIM. Label precision is automatically adjusted when the scale is manually set. Adding text to rotated graphs had the wrong angle for the box. Startangle was ignored if only one slice in a Pie was !=0. Arrays with non-consecutive indexes were not handled as URL arguments for CSIM. There is an additional error check for accumulated line plots. Incorrect handling of small slices has been fixed. Output parameters to the headers_sent() method call are initialized.
