Parameters ---------- close : bool, optional If true, a ``plt.close('all')`` call is automatically issued after sending all the figures. If this is set, the figures will entirely removed from the internal list of figures. block : Not used. The `block` parameter is a Matplotlib experimental parameter. We accept it in the function signature for compatibility with other backends.

This function is meant to be used as a post_execute callback in IPython, so user-caused errors are handled with showtraceback() instead of being allowed to raise. If this function is not called from within IPython, then these exceptions will raise.

Optionally pass quality for JPEG. For example, this enables PNG and JPEG output with a JPEG quality of 90%:: In [1]: set_matplotlib_formats('png', 'jpeg', quality=90) To set this in your config files use the following:: c.InlineBackend.figure_formats = {'png', 'jpeg'} c.InlineBackend.print_figure_kwargs.update({'quality' : 90}) Parameters ---------- *formats : strs One or more figure formats to enable: 'png', 'retina', 'jpeg', 'svg', 'pdf'. **kwargs Keyword args will be relayed to ``figure.canvas.print_figure``.

By default, the inline backend used in the IPython Notebook will close all matplotlib figures automatically after each cell is run. This means that plots in different cells won't interfere. Sometimes, you may want to make a plot in one cell and then refine it in later cells. This can be accomplished by:: In [1]: set_matplotlib_close(False) To set this in your config files use the following:: c.InlineBackend.close_figures = False Parameters ---------- close : bool Should all matplotlib figures be automatically closed after each cell is run?
