"""Create new style sheet.
For any of the Optional fields, if that field is None then it will revert to its
matplotlib.rcParams counterpart. See for usage on rcParams. Each argument that
is optonal also describes it's mapped rcParam key below.
Args:
figsize: Size of the figure.
If ``None``, will default to the figure size of the drawing backend.
If the output is ``matplotlib``, the default
parameter is ``rcParams['figure.figsize']``.
fig_unit_h_table: Height of row of event table. See Example.
use_table: When set `True` use event table.
table_columns: Number of event table columns.
table_font_size: Font size of event table.
axis_font_size: Font size of channel aliases.
If ``None``, will revert to the axis label size of the drawing backend.
If the output is ``matplotlib``, the default parameter is
``rcParams['axes.titlesize']``.
label_font_size: Font size of labels in canvas.
icon_font_size: Size of symbols.
title_font_size: Font size of schedule name in title.
If ``None``, will default to the title font size of the drawing backend.
If the output is ``matplotlib``, the default
parameter is ``rcParams['figure.titlesize']``.
label_ch_linestyle: Line style for channel pulse label line.
label_ch_color: Color code or name of color for channel pulse label line.
label_ch_alpha: Transparency for channel pulse label line from 0 to 1.
d_ch_color: Color code or name of colors for real and imaginary part
of waveform at d channels.
u_ch_color: Color code or name of colors for real and imaginary part
of waveform at u channels.
m_ch_color: Color code or name of colors for real and imaginary part
of waveform at m channels.
s_ch_color: Color code or name of color for snapshot channel line.
s_ch_linestyle: Line style for snapshot line.
table_color: Color code or name of color for event table columns of
time, channel, event information.
bg_color: Color code or name of color for canvas background.
num_points: Number of points for interpolation of each channel.
dpi: Resolution in the unit of dot per inch to save image.
If ``None``, will revert to the DPI setting of the drawing backend.
If the output is ``matplotlib``, the default
parameter is ``rcParams['figure.dpi']``.
remove_spacing: Remove redundant spacing
when the waveform has no negative values.
max_table_ratio: Maximum portion of the plot the table can take up.
Limited to range between 0 and 1.
vertical_span: Spacing on top and bottom of pulse canvas.
axis_formatter: Format of horizontal axis of the plot. This is convenient when
you set ``dt`` option for the drawer. For example, formatter of ``%.3e`` gives you
horizontal axis values in the scientific notation with 3 digits.
Example:
Height of the event table is decided by multiple parameters.::
figsize = (10.0, 12.0)
fig_unit_h_table = 0.4
table_columns = 2
max_table_ratio = 0.5
With this setup, events are shown in double-column style with
each line height of 0.4 inch and the table cannot exceed 5 inch.
Thus 12 lines are maximum and up to 24 events can be shown.
If you want to show more events, increase figure height or
reduce size of line height and table font size.
