When using the rootlocus function the plot containing all the branches does not differentiate between branches. All of them are colored with the same blue.

I found a walkthrough for this, but you need to know well the transfer function you want to plot, like:
system=control.tf([1],np.convolve(np.polyadd(np.convolve([1,1],[1,1]),4),np.polyadd(np.convolve([1,3],[1,3]),4))) control.root_locus(system) plt.gca().get_lines()[1].set_color('b') plt.gca().get_lines()[2].set_color('r') plt.gca().get_lines()[3].set_color('g') plt.gca().get_lines()[4].set_color('m')

Where poles are the line [0], and the rest are the different branches. If you have zeros, then they are located in line[1], and the branches in [2],...

Is there any possibilty of colouring the different branches as MATLAB does?

Thank you for this module, I found it very useful!
