Question

How to set one to red and second to blue?

import pygal

chart = pygal.Line()

chart.x_labels = range(5)
chart.add('one', [1, None, 3, None, 5])
chart.add('two', range(5))

chart.render_to_png(__file__ + '-linear.png')

Answer 1

You can use Pygal's Custom Styles to define specific colors for the series that you are loading. The only drawback is that the colors are assigned based on series order, so in your case you should set the colors parameter to ('red','blue') so that they match your serie order.
