Consider the following:

SetOptions[Histogram, BarOrigin -> Left, 
  Frame -> {{True, None}, {True, None}}, FrameTicks -> Automatic];

data1 = {Table[1, {i, 5}], Table[5, {i, 50}], Table[3, {i, 25}], 
   Table[4, {i, 20}]};
data2 = {Table[1, {i, 3}], Table[5, {i, 20}], Table[3, {i, 25}]};
data3 = {Table[1, {i, 3}], Table[5, {i, 20}], Table[4, {i, 15}]};

histo1 = Histogram[data1]
histo2a = Show[Histogram[data1, ChartElements -> None],Histogram[data2]]
histo3a = Show[Histogram[data1, ChartElements -> None],Histogram[data3]]

histo2b = Show[Histogram[data1], Histogram[data2, ChartStyle -> Red]]    
histo3b = Show[Histogram[data1], Histogram[data3, ChartStyle -> Red]]

I would like to use the same frame/coordinate system for histo2a and histo3a as in histo1. histo3b shows how it should be (only without the grey part) and histo2a how it should not be. histo2bin addition shows the disadvantage of the Show[]-approach (one bar exceeds the frame).

Due to the latter, I was trying to extract the FrameTicks-values from histo1 and to use them for Histogram[data2] and Histogram[data3] but neitherOptions[histo1,FrameTicks],AbsoluteOptions[histo1,FrameTicks]norHistogramList[data1]` return help.

Now I would like to use exactly the same frame ticks, which were calculated based on data1 for histo2.

Neither Options[histo1,FrameTicks], AbsoluteOptions[histo1,FrameTicks] or HistogramList[data1] help. Has anyone an idea?

  • $\begingroup$ So Histogram[data2,{HistogramList[data1][[1]]}] does not do what you want ? $\endgroup$

Perhaps:

SetOptions[Histogram, BarOrigin -> Left, 
  Frame -> {{True, None}, {True, None}}, FrameTicks -> Automatic];

data1 = Table[BesselJ[1, x], {x, 0, 500}];
data2 = Table[BesselJ[1, x], {x, 0, 100}];
GraphicsGrid[{{
   histo1 = Histogram[data1],
   histo2 = Histogram[data2],
   Show[
    Histogram[data2, ChartElements -> None], 
    Histogram[data1, {HistogramList[data2][[1]]}]]}}]

enter image description here

Edit

use just 

Show[Histogram[data2, ChartElements -> None], Histogram[data1]]

if you don't want to reuse the same bins:
