 ! These graphs illustrate the correlation of the heights and di-!
 ! ameters of a set of InAs self-organized quantum-dots (QD), grown!
 ! over GaAs by means of Molecular Beam Epitaxy. !
 ! The figure was obtained by means of Atomic Force Microscopy. !
 ! The histograms was obtained from the figure by counting and !
 ! measuring the height and diameter of each quantum-dot (each !
 ! circle). The correlation gives rise to what is known as quantum-!
 ! dots families. !

 ! ==========

 ! Our figure has two panels. We start with panel (a).

 set font ss hei 0.60 just bl
 amove 1.2 8.5
 write "a."

 ! We use the 'bitmap' command to import the 'bitmap.jpg' file into the figure.
 ! The name of the image file is 'bitmap.jpg', and the resulting image will have
 ! a width of 5 cm. A nominal height of 0 tells GLE to respect the aspect ratio
 ! of the bitmap file. The import is done within a 'begin name ... end name'
 ! block to be able to refer to the image by name:

 amove 2.0 2.5
 begin name afm_image
 bitmap "bitmap.jpg" 5 0
 end name

 ! Now that the image has been named ('afm_image'), we can refer to the 'afm_image'
 ! region and its reference points (e.g, 'tc': top center; 'bl': bottom left).
 ! We can also locate their position via the ptx() and pty() functions.

 set hei 0.45 just cc
 amove ptx(afm_image.tc) pty(afm_image.tc)+0.5
 write "AFM Image"

 set lwidth 0.03

 ! We now turn to panel (b), which is a line plot in the 'hist' step style.
