Stepped through (after making sure I had the latest) and didn't learn
too much...
after this section (lines 208-213):
Plot, binsToPlot, histdataToPlot, $ ; The fudged
histogram and bin data.
Background=backcolor, $ ; The background
color of the display.
NoData=1, $ ; Draw the axes
only. No data.
XStyle=5, $ ; Exact axis
scaling. No autoscaled axes.
YRange=yrange, $ ; The Y data
range.
YStyle=5, $ ; Exact axis
scaling. No autoscaled axes.
_Extra=extra, $ ; Pass any extra
PLOT keywords.
XTICKFORMAT='(A1)', YTICKFORMAT='(A1)'
the plot window popped up blank white, and didn't change from that at
any step.

But I did learn something else...
I think this is certainly an issue with fsc_color.

IDL> plot, findgen(10)
; gives a plot white on black
IDL> plot, findgen(10), color=fsc_color('red')
; gives a plot, red on black
IDL> plot, findgen(10), color=fsc_color('red'),
background=fsc_color('white')
; gives a blank white window

I have had issues with more than one call to fsc_color in a routine
before with legend, maybe its related?
