I have created some histograms in stata to be used in an article which
is to be published.
The person responsible for preparing the artwork for the publication
has requested that I give her a
table showing the raw frequencies used in the histogram.
There are a number of histograms in the paper and   I am finding this
quite difficult  for some of them.

It is not a problem when I specified the bin, frequency and label
options as below

clear
sysuse sp500
**********************************
* with bin option
**************************************;
 histogram volume, bin(15) frequency addlabel
summarize volume
gen min_vol=r(min)
gen max_vol=r(max)
generate volumecat = autocode(volume, 15, min_vol, max_vol)
tab volumecat

However, when I wrote the original paper I created the histograms
without specifying the number of bins
e.g.

**********************************
* without bin option
**************************************;
 histogram volume, frequency addlabel


In these cases it hard to know the starting and ending points for the bins.
I wonder if anyone has an idea how to do this?
Thanks.
