Problems of pathview package written by Scott Long

[Chen Samulsion]

Dear Stata Users,

Hope someone here has used -pathview- written by Scott Long. It is a package for Stata to construct parallel coordinates for categorical Data. I installed the package from http://www.indiana.edu/~jslsoc/stata. When I run the -pvdata- command, Stata alarms me "unrecognized command: pvdata". I detect the ado files (pvdata4.ado, pvsel4.ado, pvplot4.ado), and find the problem may due to the version sign. So I substitute pvdata/pvsel/pvplot for all the pvdata4/pvsel4/pvplot4 strings. After these substitutions, the command seems to be recognized by Stata.
And I run the following codes on the dataset that show you by dataex. The -pvdata- and -pvsel- commands do not get alarm message from Stata, but unfortunately, the successive -pvplot- command is lack of luck and gets from Stata a message which showed in last code below. I wonder if there's someone familiar with -pathview- could give me some advice. Thank you.
Add: Long's PathView introduction webpage seems unmaintained http://www.indiana.edu/~jslsoc/research_pathview.htm
and the webpage attached in pvstata help file is lost http://www.indiana.edu/~jslsoc/pathview.htm

I run hammock (SSC) on the data above and get a graph like this:

hammock item1-item9

It seems that there is a bug in -pvdata- command (a part of -pathview-) that should be fixed. Using the data and codes in #1, I get the following graph. It is equivalent to the graph in #2.
