When changing the plot range of a histogram from Automatic to a plot range which exceeds the automatically calculated plot range, Mathematica draws an unwanted horizontal line which I cannot get rid of (see right histogram at value -4). Does anyone have a suggestion on that issue?
I’m running Mathematica V.8.0.1.0 on Mac OS 10.7.2.
In[1099]:=
data = {-1.2056, -1.46192, -1.30053, -2.52879, -0.99636, -1.73904, -1.164,
-1.83398,-0.97505, -0.503256, -0.63802, -0.785963, -0.711821, -0.820439, -1.8699,
-3.9659, -1.4456, -1.67021, -1.42009, -2.5644, -1.45002, -1.27806, -1.66529,
-1.67073, -3.31102, -3.38638};
HistogramLeft=Histogram[data, PlotRange -> Automatic]
HistogramRight=Histogram[data, PlotRange -> {-8, 0}]


It looks like you’re using
Frame -> {{True, False}, {True, False}}(or something similar.) If that’s the case, you can turn off the normal axes entirely withAxes->False.
