I use the following code to show a Histogram with a PDF additionally
Show [Histogram[{data}, {width}, "ProbabilityDensity", ImageSize -> {820, 530}, PlotRange -> All], Plot[PDF[NormalDistribution[mu, sigma], x], {x, -4.50,5.00}, ImageSize -> {820, 530}, PlotRange -> All]]
I have added the final picture.
Just for cosmetical points I would like to have the diagramm on the right so far that the curve will go smooth to the axis but here it is still cut at 4.
Is this possible?
thanks

PlotRangesetting toShow[]? See this, for instance. – J. M.'s missing motivation Oct 12 '16 at 06:40
