Out of bound on a simple_stacked_bar with more than 19 stacked dataset

[mielune]

Hi,

I try to build a simple_stacked_bar with 22 stacked datasets but the lib crash on the colors Limit with 16 datasets is working but I need all of the 22.

Can I have a workaround ? It seems to be linked to the colors[i] out of range line 733 The ability to setup my own colors list ?

With all datasets :

With only 16 datasets :

Kind regards,

[mielune]

I will try with

colors[i % len(colors)]

in both lines 733 and 775 to rotate on the colors if not enough available, without crash.

Hello, sorry I am a bit absent from solving issue recently, as I am (slowly) rebuilding the package from ground up.

Can I ask you to send the code you used to produce the error?

Thanks for reporting and your inputs

Hi,

A small example to reproduce this issue: with 19 items it work fine, but with 20 failed.

import plotext as plt
from random import random

nb_items = 20  # Work fine with 19
nb_data = 30

items = [f"a{x+1}" for x in range(nb_items)]
data = [[int(random() * 100) for y in range(nb_data)] for x in range(nb_items)]
labels = [f"l{y+1}" for y in range(nb_data)]

plt.simple_stacked_bar(labels, data, labels=items, title="Test")
plt.show()

Result:

I just created a PR with my fix: https://github.com/piccolomo/plotext/pull/192

Sorry if not in the process, I'm not used to work on Github.

Just to update and apologise: I have been quite busy rewriting the package from ground up and will update.
