Some Monte Carlo software offer the facility to smooth a histogram plot. We don't recommend this approach because: a) it suggests greater accuracy than actually exists; b) it fits a spline curve that will accentuate (unnecessarily) any peaks and troughs, as well as adding non-existent features to the curve,  and c) if the scale remains the same, the area does not integrate to equal one unless the original band widths were one x-axis unit wide.
