for selected and unselected data
he utilization of selection and linking for scatterplots can be highly effective,
but it is dependent on the data distribution. Consider the two variables just men-
tioned above, Cash.TA and Intg.TA, and their distribution for the companies that
went bankrupt. A scatterplot can be drawn with a little α-blending,asshownonthe

been used for the highlighted cases, as they then disappear on this scale.) Both plots
contribute information but neither is fully satisfactory. Another alternative would be
to draw a pair of scatterplots, one for each of the two groups of companies, but this is
