Mar 01, 2011 · hello community, I'm slowly losing my mind trying to do something rather simple. A true color image does not use a colormap; instead, the color values for each pixel are stored directly as RGB triplets. We can increase the distance between the y-label and the y-axis in the following way: Former "Pickmaster" (and current blogger) Doug Hull suggested that John Iversen's color freezer might be "Pickworthy. a vector of reals ([xmin xmax ymin ymax] or [xmin xmax ymin ymax zmin zmax]). matlab axis ij
