That plot looks to me as though a value-to-color transformation is
performed on the logarithm of gene expression. The scale bar can be
roughly reproduced like this:
The horizontal lengths of the stacked bars of the plot can then be
adjusted to the number of subjects in a given bin of log gene
expressions. A tricky plot, but it can be done in R.
