# Plotting sequences with same label, and color in python

names = ['a', 'b', 'c', 'a', 'c', 'd']    # sample labels
fig = plt.figure()                        # save your figure in a variable for later access
for i in range(5):
    plt.plot([0,1], [i,i], label=names[i])

plt.legend()                              # still wrong legend for comparison purpose

ax = fig.gca()                            # get the current axis

for i, p in enumerate(ax.get_lines()):    # this is the loop to change Labels and colors
    if p.get_label() in names[:i]:    # check for Name already exists
        idx = names.index(p.get_label())       # find ist index
        p.set_c(ax.get_lines()[idx].get_c())   # set color
        p.set_label('_' + p.get_label())       # hide label in auto-legend
plt.legend(loc='center')


# new color for new label
labels = [str(x) for x in values]
cmap = plt.get_cmap('Dark2', len(labels))
fig = plt.figure(figsize=(8, 10))  # save your figure in a variable for later access
for i, fk in enumerate(file_keys):
    df = df[df['file_key'] == int(fk)]
    plt.plot(a, b, label=labels[i], c=cmap(i), linewidth=1
