Parallel plot or Parallel Coordinates Plots allow to compare the feature of several individual observations on a set of numerical variables. Each vertical bar represents a variable and usually has its own scale. (The
units can even be different!). Values are then plotted as series of lines connected across each axis. Playing with colour can then be used to represent different groups of individual, or highlight a specific one. That should allow to
detect interesting patterns! Don’t forget to play with the order of your axis. Indeed, parallel plot mainly allows to compare variations of adjacent axis, so changing the order can lead to the discovering of new patterns.
