Re: [Matplotlib-users] colorbllind problem

Hi,
I get right one plot, but this other one works in a strange way:
it restarts to give the darker color to a line. I would like to assign the
colors in the right order so the colorblind guy that works with me could
see the differences like a light growing. (I attach the image) do you
understand where am I doing wrong? (before this piece of code I use other
color palette but I think they have no effect on the following ones)
zipPARApha = zip(Pampli, Pgamma, Pecut, Pb, g)
myPalet1 = sns.color_palette("RdPu_r", 10)
sns.set_color_palette(myPalet1)
lotgr = plt.figure()
axius = lotgr.add_subplot(111)
for n, (a1,b1,c1,d1,pha) in enumerate(zipPARApha):
if n % 18 == 0:
fittedval = spock(logeels, a1, b1, c1, d1)
phaint = int(pha)
angli = str(phaint)
imig = axius.plot(logeels, fittedval, label=angli)
axius.set_title('phase resolved spectra, ' + lightitle)
axius.set_ylim([-100, 1])
axius.legend(bbox_to_anchor=(1.05, 1), loc=9, borderaxespad=0.)
lotgr.canvas.draw()
thanks
Gabriele
