st: Alignment Issue: Twoway (histogram)(connected)

[Niall MacDonald <niallm@ualberta.ca>]

Hi,

I am having difficulties getting the datapoints on a twoway plot  
(histogram and connected line) to align correctly.  The problem  
arises even when a simple script is used:

twoway (connected tot_num doy)(histogram doy, discrete freq barwidth(1))

tot_num numbers the events that occur over the year consecutively;  
doy is the day of the year on which each event occurred.

The problem is, that despite using a common x-axis, the corresponding  
bars on the frequency histogram and points on the connected line  
graph do not line up.  The majority of the points on the connected  
line appear to be shifted to the right of their corresponding  
frequency bars.

Any help would be appreciated!
