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?
