It would be pretty neat if Histogram plots accepted a parameter for a fixed bin width - or alternatively, accepted an array of values representing bin edges, as the Matplotlib implementation does:
bins: int or sequence or str, default: rcParams["hist.bins"] (default: 10)
If bins is an integer, it defines the number of equal-width bins in the range.
If bins is a sequence, it defines the bin edges, including the left edge of the first bin and the right edge of the last bin; in this
case, bins may be unequally spaced. All but the last (righthand-most) bin is half-open.
Such a feature would promote more consistent visuals and facilitate comparison when attempting to overlay histograms:
define_color("vandeusen", [73,92,111])
define_color("cordovan", [152,68,71])
X1 = randn(100) .+= 2.0
X2 = 4*randn(100)
p = Axis([
Plots.Histogram(X1, density=true,
style="vandeusen, fill=vandeusen,opacity=0.5"),
Plots.Histogram(X2, density=true,
style="cordovan, fill=cordovan,opacity=0.5")
],
ymin=0, ylabel="Density", xlabel = "X")

Definitely a low-priority issue though!
