histogram - changing bin width

[Tara Boyle]

I currently have this histogram - which is the same as the one posted in the post here plotting ecdf graph - too many lines - Statalist

(but without ecdf - as I can't find a solution to the problem)

I was told by my senior that I need to make it more 'readable' the histogram

I've tried using Freedman- Diaconis rule - which essentially creates the same bin width as stata's.
width 12, 41 bins
My max value is 498
Min value is 1

How can I make it more readable, perhaps each bar having a width of 10 ? So for the reader it may be easier to reading every 10....
Unless you have any other ideas how to make it more readable??

Among various possibilities to consider is to use logarithmic scale. I often prefer quantile plots in any case.

Hm, I was hoping to keep it with whole numbers on the x axis rather than using a log scale - it’s easily interpreted for statisticians but not amongst medical staff. As are quantile plots.

So no other ways to fix this ?

At a guess you have about a hundred distinct values, which should mean that (xvarm is the variable name you used in your linked post; change to suit circumstances)

preserve 
contract xvarm
dataex, count(498) 
restore

will yield dataex output that you can show us. The 498 is pessimistic on my part given your indication that your values are integers.

I am a geographer and think I understand quantile plots, so why doubt medical people on that?
