to class values or cluster numbers
- Parameters:
cols
- the list of colours to use
setXindex
public void setXindex(int x)
Set the index of the attribute to go on the x axis
- Parameters:
x
- the index of the attribute to use on the x axis

Set the index of the attribute to use for colouring
- Parameters:
c
- the index of the attribute to use for colouring
