The commands ROTATE/CLOCK , ROTATE/COUNTER_CLOCK and FLIP/IMAGE enable to perform any rotation by a multiple of 90 degrees and image flipping without interpolating the pixel values. The command REBIN/ROTATE can be used for any rotation but in the general case will interpolate the pixel values. ...

The size of font used by PGPLOT for labels and other text on the plots can be changed using the PGSCH command, which takes one argument which is the relative height of the characters. If this argument is greater than one then to font size will be larger than default. ... The easy way to fix this is to call the PGVSTD command after the call to PGSCH. This command allows a sufficient margin for usual labelling, taking into account the current size of the font. ...
