Parallel Coordinates and playing around with graph

[Shama Alam]

In using the parcoord command, I am finding it difficult to move from the default colors provided by STATA. More specifically I conducted a cluster analysis using a model containing 5 variables and am reviewing the parallel coordinates graph by 6 groups. The colors are specified in the colorby(idvar) which represent the category of minorities served (3 categories, 3 colors) - I would like to increase intensity of the colors and also change the default. Any thoughts?

The user-written program - parcoord - is STB-29, which means ‘quite old’ program, since it is classified as Stata Technical Bulletin.

According to the help file,
graph_options are any of the options allowed with graph, twoway, except for: by, b2title, connect, noaxis, pen, symbol, tlabel, xlabel, xline, ylabel, yline

This may produce issues related to the old program as well as the - potentially - new Stata versions.

As Marcos Almeida points out parcoord is an old command -- written in 1995 for Stata version 4. It works with what is now called graph7 so specifically

help gr7twoway

tells you what you can tune. That doesn't include intensity of colour. See also parplot (SSC) for a more recent stab at parallel coordinates.
