I use errorxy, but I've modified it so that the data point markers plot over the error bars and so that I can change the thickness of the data point markers. The code is structured well so that it is easy to modify.

Seems useful. I have only a couple of minor points. The use of property/value pairs is very valuable for tools like this where you have many different parameters, most of which have default values. BUT - do not make those properties case sensitive as has been done here. The user does not want to remember that to specify which column the y errors comes from, they must use the property 'ColYe'. Instead, allow them to specify 'colye' instead. Your code should ignore case. The function "lower" can help you here. Next, its also nice to allow the user to shorten a property, as long as that shortening is unambiguous. Thus, properties 'hist', 'histfacecolor' and 'histedgecolor' should be able to be shortened to as small as 'hist', 'histf', or 'histe'. Strmatch or strncmpi can help with this.

A great m files that should be on standard Matlab distribution. Well documented and working all right.
