"""Convert a matplotlib figure to plotly dictionary and send.
All available information about matplotlib visualizations are stored
within a matplotlib.figure.Figure object. You can create a plot in python
using matplotlib, store the figure object, and then pass this object to
the fig_to_plotly function. In the background, mplexporter is used to
crawl through the mpl figure object for appropriate information. This
information is then systematically sent to the PlotlyRenderer which
creates the JSON structure used to make plotly visualizations. Finally,
these dictionaries are sent to plotly and your browser should open up a
new tab for viewing! Optionally, if you're working in IPython, you can
set notebook=True and the PlotlyRenderer will call plotly.iplot instead
of plotly.plot to have the graph appear directly in the IPython notebook.
Note, this function gives the user access to a simple, one-line way to
render an mpl figure in plotly. If you need to trouble shoot, you can do
this step manually by NOT running this fuction and entereing the following:
===========================================================================
from plotly.matplotlylib import mplexporter, PlotlyRenderer
# create an mpl figure and store it under a varialble 'fig'
renderer = PlotlyRenderer()
exporter = mplexporter.Exporter(renderer)
exporter.run(fig)
===========================================================================
You can then inspect the JSON structures by accessing these:
renderer.layout -- a plotly layout dictionary
renderer.data -- a list of plotly data dictionaries

Keywords arguments with constant defaults:
rows (kwarg, int greater than 0, default=1):
Number of rows in the subplot grid.
cols (kwarg, int greater than 0, default=1):
Number of columns in the subplot grid.
shared_xaxes (kwarg, boolean or list, default=False)
Assign shared x axes.
If True, subplots in the same grid column have one common
shared x-axis at the bottom of the gird.
To assign shared x axes per subplot grid cell (see 'specs'),
send list (or list of lists, one list per shared x axis)
of cell index tuples.
shared_yaxes (kwarg, boolean or list, default=False)
Assign shared y axes.
If True, subplots in the same grid row have one common
shared y-axis on the left-hand side of the gird.
To assign shared y axes per subplot grid cell (see 'specs'),
send list (or list of lists, one list per shared y axis)
of cell index tuples.
start_cell (kwarg, 'bottom-left' or 'top-left', default='top-left')
Choose the starting cell in the subplot grid used to set the
domains of the subplots.
print_grid (kwarg, boolean, default=True):
If True, prints a tab-delimited string representation of
your plot grid.
Keyword arguments with variable defaults:
horizontal_spacing (kwarg, float in [0,1], default=0.2 / cols):
Space between subplot columns.
Applies to all columns (use 'specs' subplot-dependents spacing)
vertical_spacing (kwarg, float in [0,1], default=0.3 / rows):
Space between subplot rows.
Applies to all rows (use 'specs' subplot-dependents spacing)
subplot_titles (kwarg, list of strings, default=empty list):
Title of each subplot.
"" can be included in the list if no subplot title is desired in
that space so that the titles are properly indexed.
specs (kwarg, list of lists of dictionaries):
Subplot specifications.
ex1: specs=[[{}, {}], [{'colspan': 2}, None]]
ex2: specs=[[{'rowspan': 2}, {}], [None, {}]]
- Indices of the outer list correspond to subplot grid rows
starting from the bottom. The number of rows in 'specs'
must be equal to 'rows'.
- Indices of the inner lists correspond to subplot grid columns
starting from the left. The number of columns in 'specs'
must be equal to 'cols'.
- Each item in the 'specs' list corresponds to one subplot
in a subplot grid. (N.B. The subplot grid has exactly 'rows'
times 'cols' cells.)
- Use None for blank a subplot cell (or to move pass a col/row span).
- Note that specs[0][0] has the specs of the 'start_cell' subplot.
- Each item in 'specs' is a dictionary.
The available keys are:
* is_3d (boolean, default=False): flag for 3d scenes
* colspan (int, default=1): number of subplot columns
for this subplot to span.
* rowspan (int, default=1): number of subplot rows
for this subplot to span.
* l (float, default=0.0): padding left of cell
* r (float, default=0.0): padding right of cell
* t (float, default=0.0): padding right of cell
* b (float, default=0.0): padding bottom of cell
- Use 'horizontal_spacing' and 'vertical_spacing' to adjust
the spacing in between the subplots.
insets (kwarg, list of dictionaries):
Inset specifications.
- Each item in 'insets' is a dictionary.
The available keys are:
* cell (tuple, default=(1,1)): (row, col) index of the
subplot cell to overlay inset axes onto.
* is_3d (boolean, default=False): flag for 3d scenes
* l (float, default=0.0): padding left of inset
in fraction of cell width
* w (float or 'to_end', default='to_end') inset width
in fraction of cell width ('to_end': to cell right edge)
* b (float, default=0.0): padding bottom of inset
in fraction of cell height
* h (float or 'to_end', default='to_end') inset height
in fraction of cell height ('to_end': to cell top edge)
column_width (kwarg, list of numbers)
Column_width specifications
- Functions similarly to `column_width` of `plotly.graph_objs.Table`.
Specify a list that contains numbers where the amount of numbers in
the list is equal to `cols`.
- The numbers in the list indicate the proportions that each column
domains take across the full horizontal domain excluding padding.
- For example, if columns_width=[3, 1], horizontal_spacing=0, and
cols=2, the domains for each column would be [0. 0.75] and [0.75, 1]
row_width (kwargs, list of numbers)
Row_width specifications
- Functions similarly to `column_width`. Specify a list that contains
numbers where the amount of numbers in the list is equal to `rows`.
- The numbers in the list indicate the proportions that each row
domains take along the full vertical domain excluding padding.
- For example, if row_width=[3, 1], vertical_spacing=0, and
cols=2, the domains for each row from top to botton would be
[0. 0.75] and [0.75, 1]
