gwpy.plot
GWpy overrides the default ~matplotlib.axes.Axes class with one that uses a different default legend handler for line plots. This means that, by default, lines in a legend will be thicker than on a standard matplotlib figure:
>>> import gwpy # <- import anything from gwpy >>> from matplotlib import pyplot >>> fig = pyplot.figure() >>> ax = fig.gca() >>> ax.plot(range(10), label='My data') >>> ax.legend() >>> fig.show()
This can be disabled by passing an empty handler_map to the ~matplotlib.axes.Axes.legend method:
>>> fig = pyplot.figure() >>> ax = fig.gca() >>> ax.plot(range(10), label='My data') >>> ax.legend(handler_map=None) >>> fig.show()
Similarly, you can implement your own custom legend handler and overwrite things yourself. Below is a simple example, but for more details see matplotlib:sphx_glr_tutorials_intermediate_legend_guide.py:
>>> from matplotlib.legend_handler import HandlerLine2D >>> from matplotlib.lines import Line2D >>> class MyHandler(HandlerLine2D): ... def create_artists(self, args,kwargs): ... line, marker = super(MyHandler, self).create_artists( ...args, ... **kwargs, ... ) ... line.set_linewidth(4.) ... line.set_linestyle('--') ... return line, marker >>> fig = pyplot.figure() >>> ax = fig.gca() >>> ax.plot(range(10), label='My data') >>> ax.legend(handler_map={Line2D: MyHandler()}, handlelength=10) >>> fig.show()
