SCr

SCr # # # # Immediately change the color representation for the specified color index. The first number is the color index and the following three numbers give the red, green, and blue color intensities and must lie in the range 0.0 to 1.0. This command only works on color devices for which the color representation can be changed. Since the command is immediate, the plotting device must be open or able to be opened in order for the comamnd to have an effect.

Black/White/Default

SCr [Black|White|Default] This allows PLT to override the default PGPLOT background color. In particular, /XS and /GIF devices produce white lines on a black background, whereas a PostScript hardcopy would be black lines on white paper. Thus

PLT> SCr White

will always force the background to be white. Note, SCr Black is not recommended as it would require white toner and black paper in order for it to work with PostScript devices. SCr Default restores the default behavior where PGPLOT picks the background color.

examples

PLT> SCR 0 1. 1. 1.  ! Set the background color to be white
PLT> SCR 1 0 0 0     ! Plot color index 1 in black
PLT> SCR 2 0 1 0     ! Plot color index 2 in green
