      Plot a 2D matrix using the cmap1 palette.  The color scale is
      automatically adjusted to use the maximum and minimum values in
      idata as valuemin and valuemax in a call to plimagefr.
    
idata
	  (PLFLT_MATRIX
	    A matrix containing function values to plot.  Should have
	    dimensions of nx by ny.

	    The x and y index ranges are
	    linearly transformed to these world coordinate ranges such that
	    idata[0][0] corresponds to (xmin,
	    ymin) and idata[nx - 1][ny - 1]
	    corresponds to (xmax, ymax).
