Legend

show_legend

You can remove legend by setting this to False

chart = pygal.Line(show_legend=False)
chart.add('Serie 1', [1, 2, 3])
chart.add('Serie 2', [4, 2, 0])
chart.add('Serie 3', [1, -1, 1])
chart.add('Serie 4', [3, 1, 5])
chart.render()

legend_at_bottom

You can put legend at bottom by setting legend_at_bottom to True:

chart = pygal.Line(legend_at_bottom=True)
chart.add('Serie 1', [1, 2, 3])
chart.add('Serie 2', [4, 2, 0])
chart.add('Serie 3', [1, -1, 1])
chart.add('Serie 4', [3, 1, 5])
chart.render()

legend_at_bottom_columns

Force the number of legend columns when set at bottom

chart = pygal.Line(legend_at_bottom=True, legend_at_bottom_columns=4)
chart.add('Serie 1', [1, 2, 3])
chart.add('Serie 2', [4, 2, 0])
chart.add('Serie 3', [1, -1, 1])
chart.add('Serie 4', [3, 1, 5])
chart.render()

legend_box_size

chart = pygal.Line(legend_box_size=18)
chart.add('Serie 1', [1, 2, 3])
chart.add('Serie 2', [4, 2, 0])
chart.add('Serie 3', [1, -1, 1])
chart.add('Serie 4', [3, 1, 5])
chart.render()

truncate_legend

By default long legends are automatically truncated at reasonable length to fit in the graph.

You can override that by setting truncation lenght with truncate_legend.

chart = pygal.Line(truncate_legend=17)
chart.x_labels = [
    'This is the first point !',
    'This is the second point !',
    'This is the third point !',
    'This is the fourth point !']
chart.add('line', [0, .0002, .0005, .00035])
chart.render()

or disable it by setting this to -1

chart = pygal.Line(truncate_legend=-1)
chart.x_labels = [
    'This is the first point !',
    'This is the second point !',
    'This is the third point !',
    'This is the fourth point !']
chart.add('line', [0, .0002, .0005, .00035])
chart.render()
