Description
-----------

^ghistcum^ plots a histogram showing the frequency distribution of
varname, overlaid with the cumulative distribution of the variable
as generated by ^cumul^. 

Options
-------

^bin(^#^)^ specifies the number of bins to be used in the histogram. 
Default is 5.

two_way options are options allowed with ^graph, twoway^ except for 

    ^bbox(0,0,20000,30000,850,390,0)^

    ^noaxis^ 
    ^symbol(i)^
    ^yscale(0,1)^ 
    
which are hard-wired into the program, and ^by( )^ which is not supported. 
Defaults of other options are 

    ^connect(J)^ for connecting cumulative distribution function 
    ^pen(4)^ for showing c.d.f. 
    ^t1title("Histogram and cumulative distribution of ^varname^")^
    ^yla^
