Plotting with automatic colours & markers

[Etienne Le Sueur]

Hi everyone,

I'm using octave 3.0.0 on Mac OSX, with gnuplot 4.2.

I have a set of data which produces a plot with about 12 lines. 
unfortunately, because there are a limited amount of colours, the 
colours are repeated, and there is no way to determine which line in the 
legend corresponds to which plotted line.

Is there any way to have the plot function automatically handle this? or 
can anyone post an example of how to do it manually?

I am calling the plot function once with a matrix of values 
corresponding to each line.

Regards,
