plopp.backends.matplotlib.canvas.Canvas#
- class plopp.backends.matplotlib.canvas.Canvas(ax=None, cax=None, figsize=None, title=None, grid=False, user_vmin=None, user_vmax=None, aspect=None, cbar=False, legend=True, **ignored)[source]#
Matplotlib-based canvas used to render 2D graphics. It provides a figure and some axes, as well as functions for controlling the zoom, panning, and the scale of the axes.
- Parameters:
ax (
Optional
[Axes
], default:None
) – If supplied, use these axes to create the figure. If none are supplied, the canvas will create its own axes.cax (
Optional
[Axes
], default:None
) – If supplied, use these axes for the colorbar. If none are supplied, and a colorbar is required, the canvas will create its own axes.figsize (
Optional
[tuple
[float
,float
]], default:None
) – The width and height of the figure, in inches.title (
Optional
[str
], default:None
) – The title to be placed above the figure.grid (
bool
, default:False
) – Display the figure grid ifTrue
.user_vmin (
Union
[Variable
,float
,None
], default:None
) – The minimum value for the y axis (1d plots only).user_vmax (
Union
[Variable
,float
,None
], default:None
) – The maximum value for the y axis (1d plots only).aspect (
Optional
[Literal
['auto'
,'equal'
,None
]], default:None
) – The aspect ratio for the axes.cbar (
bool
, default:False
) – Add axes to host a colorbar ifTrue
.legend (
bool
|tuple
[float
,float
], default:True
) – Show legend ifTrue
. Iflegend
is a tuple, it should contain the(x, y)
coordinates of the legend’s anchor point in axes coordinates.
