Plot¶

class floulib.Plot¶

Bases: object

This class contains methods to plot various object.

ax = None¶: The Axes of the subplot.

plot(nrows=1, ncols=1, **kwargs)¶

Generic plot method

Parameters:

nrows (int, optional) – Number of rows of the plot. The default is 1.
ncols (int, optional) – Number of columns of the plot. The default is 1.
**kwargs –
- For Discrete:
  - index: index of the plot. The default is 0.
  - xlim: x-limit for the plot. The default is None.
  - ylim: y-limit for the plot. The default is [0, 1.05].
  - coeff: coefficient used for scatter plot. The default is 0.25.
  - scatter: if True scatter plot is used otherwise conventional plot is used. Default is True.
  - any keyword argument accepted by matplotlib.scatter if scatter is True or by matplotlib.plot otherwise.
- For Multilinear:
  - index: index of the plot. The default is 0.
  - xlim: x-limit for the plot. The default is None.
  - ylim: y-limit for the plot. The default is [0, 1.05].
  - vlines: if True, dashed vertical lines are plotted for each point. Default is False.
  - any keyword argument accepted by matplotlib.plot.
- For Rule or Rules:
  - xlim: x-limit for the plot. The default is None.
  - ylim: y-limit for the plot. The default is None.
  - implication: if True, an implicative view of the rule is considered for plotting the support, otherwise conjunctive view is considered. Default is False.
  - any keyword argument accepted by shapely.plotting.plot_polygon.
- For Smiley:
  - index: index of the plot. The default is 0.
- For Term or Terms:
  - index: index of the plot. The default is 0.
  - any keyword argument accepted by matplotlib.plot.
- For Variable:
  - index: index of the plot. The default is 0.
  - any keyword argument accepted by the type of the variable.

Returns:

The plot.

Return type:

Plot

add_plot(other=None, **kwargs)¶

Adds a plot to a plot.

Parameters:

other (Discrete | Multilinear | Rule | Rules | Smiley | Term | Terms | Variable) – Parameter to add in the plot.
**kwargs – Same parameters as for the method plot.

Raises:

Exception – Raised if the parmeter other is not provided.

Returns:

The plot.

Return type:

Plot

Example

>>> from floulib import Discrete, Triangle
>>> A = Triangle( 1, 2, 3, label = 'A')
>>> B = Triangle(2, 3, 4, label = 'B')
>>> A.plot(xlim = [0, 5]).add_plot(B)

>>> C = Discrete(('a', 0.3), ('b', 0.6), label = 'C')
>>> A.plot(nrows = 2, xlim = [0, 5]).add_plot(B).add_plot(C, index = 1)

color(color)¶

Sets the color of the plot.

Parameters:: color (matplotlib.colors) – The color.
Returns:: The multilinear fuzzy subset.
Return type:: Multilinear

Example

>>> from floulib import Triangle
>>> A = Triangle( 1, 2, 3)
>>> A.color('orange').plot()

label(label)¶

Sets the label associated with the plot.

Parameters:: label (str) – The label.
Returns:: The plot object.
Return type:: Plot

Example

>>> from floulib import Triangle
>>> A = Triangle( 1, 2, 3)
>>> A.label('A').plot()

legend(index=0)¶

Builds the legend.

Parameters:: index (int) – index of the plot. The default is 0.
