Parallel axis plots can highlight correlation in a multidimensional data set.
Each input column is associated with a separately scaled vertical axis.
The column values read from each line of input are connected by line segments
drawn from axis 1 to axis 2 to axis 3 and so on. That is, each line of input
is represented by a separate line in the parallel axes plot.
It is common to use some discrete categorization to assign line colors,
allowing visual exploration of the correlation between this categorization and
the axis dimensions.
By default gnuplot will automatically determine the range and scale of the
individual axes from the input data, but the usual set axis range commands
can be used to customize this. See set paxis (p.
).
