change color

red,green,bluefloat--rgb components (0..1)


plcolor changes the color for subsequent plotting operations. The parameters give the red, green and blue fraction, such that black is represented by 0,0,0 and white by 1,1,1. For many colors, macros have been predefined, thus permitting the replacement of the three parameters with one predefined constant. Thus white may also be set with plcolor(White) and black with plcolor(Black). The following table shows the predefined colors; a red printed color indicates that 1, 2, 3 or 4 may be appended, where 1 is equivalent to nothing appended, and 2, 3 and 4 represent darker colors (100, 93, 80 and 55% respectively).
