see the following code


%ex7 = "\Example Files\EV7 Manual Data"
%ch13 = "\Chapter 13 - Graphing Data"
%wf = @evpath + %ex7 +%ch13 +"\geyser"
wfopen %wf
freeze(gf00) length.hist
freeze(gf10) length.distplot hist
freeze(gf11) length.distplot hist(rightclosed)

%wf = @evpath + %ex7 +%ch13 +"\cdrate"
pageload(page=CDrate) %wf
freeze(gf00) cdrate.hist
freeze(gf10) cdrate.distplot hist
freeze(gf11) cdrate.distplot hist(rightclosed)

note that in Geyser's data, gf00 is similar to gf11, although the x-tick is less 0.1. However, in page CDrate, gf00 is similar to gf10. How to understand the behavior of cmd hist?

Not sure what you're asking.

The hist command just shows a representative histogram of the data, where bin width etc.. are chosen to make the histogram "nice".

Thanks.
I first think that "hist" is equivalent to "distplot hist". now I know it is not, "hist" may adjust something like bin, anchor and how obs on end-point are handled.

displot chooses a set of defaults for the bin placement and width that may differ from those in hist. If you look at the options for the histogram in distplot/hist you will see that you have greater ability in distplot to control those items.

thanks
on histograms, distplot is more full-featured and customizable. I just feel a bit odd that hist sometimes behave like "distplot hist(rightclosed)" and at other time like "distplot hist"
