Methods defined here:
- get_default_filetype(self)
- print_svg(self, filename, *args, **kwargs)
- print_svgz(self, filename, *args, **kwargs)
Data and other attributes defined here:
- filetypes = {'svg': 'Scalable Vector Graphics', 'svgz': 'Scalable Vector Graphics'}
Methods inherited from matplotlib.backend_bases.FigureCanvasBase:
- __init__(self, figure)
- blit(self, bbox=None)
- blit the canvas in bbox (default entire canvas)
- button_press_event(self, x, y, button, guiEvent=None)
- Backend derived classes should call this function on any mouse
button press. x,y are the canvas coords: 0,0 is lower, left.
button and key are as defined in MouseEvent
- button_release_event(self, x, y, button, guiEvent=None)
- Backend derived classes should call this function on any mouse
button release. x,y are the canvas coords: 0,0 is lower, left.
button and key are as defined in MouseEvent
- draw(self, *args, **kwargs)
- Render the figure
- draw_cursor(self, event)
- Draw a cursor in the event.axes if inaxes is not None. Use
native GUI drawing for efficiency if possible
- draw_event(self, renderer)
- draw_idle(self, *args, **kwargs)
- draw only if idle; defaults to draw but backends can overrride
- flush_events(self)
- Flush the GUI events for the figure. Implemented only for
backends with GUIs.
- get_supported_filetypes(self)
- get_supported_filetypes_grouped(self)
- get_width_height(self)
- return the figure width and height in points or pixels
(depending on the backend), truncated to integers
- key_press_event(self, key, guiEvent=None)
- key_release_event(self, key, guiEvent=None)
- motion_notify_event(self, x, y, guiEvent=None)
- Backend derived classes should call this function on any
motion-notify-event. x,y are the canvas coords: 0,0 is lower, left.
button and key are as defined in MouseEvent
- mpl_connect(self, s, func)
- Connect event with string s to func. The signature of func is
def func(event)
where event is a MplEvent. The following events are recognized
'resize_event',
'draw_event',
'key_press_event',
'key_release_event',
'button_press_event',
'button_release_event',
'scroll_event',
'motion_notify_event',
'pick_event',
For the three events above, if the mouse is over the axes,
the variable event.inaxes will be set to the axes it is over,
and additionally, the variables event.xdata and event.ydata
will be defined. This is the mouse location in data coords.
See backend_bases.MplEvent.
return value is a connection id that can be used with
mpl_disconnect
- mpl_disconnect(self, cid)
- disconnect callback id cid
- onHilite(self, ev)
- Mouse event processor which highlights the artists
under the cursor. Connect this to the motion_notify_event
using canvas.mpl_connect('motion_notify_event',canvas.onHilite)
- onRemove(self, ev)
- Mouse event processor which removes the top artist
under the cursor. Connect this to the mouse_press_event
using canvas.mpl_connect('mouse_press_event',canvas.onRemove)
- pick(self, mouseevent)
- pick_event(self, mouseevent, artist, **kwargs)
- This method will be called by artists who are picked and will
fire off PickEvent callbacks registered listeners
- print_bmp = print_raw(self, *args, **kwargs)
- print_emf(self, *args, **kwargs)
- print_eps(self, *args, **kwargs)
- print_figure(self, filename, dpi=None, facecolor='w', edgecolor='w', orientation='portrait', format=None, **kwargs)
- Render the figure to hardcopy. Set the figure patch face and edge
colors. This is useful because some of the GUIs have a gray figure
face color background and you'll probably want to override this on
hardcopy.
filename - can also be a file object on image backends
orientation - only currently applies to PostScript printing.
dpi - the dots per inch to save the figure in; if None, use savefig.dpi
facecolor - the facecolor of the figure
edgecolor - the edgecolor of the figure
orientation - 'landscape' | 'portrait' (not supported on all backends)
format - when set, forcibly set the file format to save to
- print_pdf(self, *args, **kwargs)
- print_png(self, *args, **kwargs)
- print_ps(self, *args, **kwargs)
- print_raw(self, *args, **kwargs)
- print_rgb = print_raw(self, *args, **kwargs)
- resize(self, w, h)
- set the canvas size in pixels
- resize_event(self)
- scroll_event(self, x, y, button, guiEvent=None)
- Backend derived classes should call this function on any
scroll wheel event. x,y are the canvas coords: 0,0 is lower,
left. button and key are as defined in MouseEvent
- set_window_title(self, title)
- Set the title text of the window containing the figure. Note that
this has no effect if there is no window (eg, a PS backend).
- switch_backends(self, FigureCanvasClass)
- instantiate an instance of FigureCanvasClass
This is used for backend switching, eg, to instantiate a
FigureCanvasPS from a FigureCanvasGTK. Note, deep copying is
not done, so any changes to one of the instances (eg, setting
figure size or line props), will be reflected in the other
Data and other attributes inherited from matplotlib.backend_bases.FigureCanvasBase:

Methods defined here:
- __init__(self, width, height, svgwriter, basename=None)

- get_canvas_width_height(self)
- get_text_width_height_descent(self, s, prop, ismath)

- option_image_nocomposite(self)
- if svg.image_noscale is True, compositing multiple images into one is prohibited
Data and other attributes defined here:
- FONT_SCALE = 100.0
- fontd = {}
Methods inherited from matplotlib.backend_bases.RendererBase:
- draw_quad_mesh(self, master_transform, cliprect, clippath, clippath_trans, meshWidth, meshHeight, coordinates, offsets, offsetTrans, facecolors, antialiased, showedges)
- This provides a fallback implementation of draw_quad_mesh that
generates paths and then calls draw_path_collection.
- draw_tex(self, gc, x, y, s, prop, angle, ismath='TeX!')
- get_image_magnification(self)
- Get the factor by which to magnify images passed to draw_image.
Allows a backend to have images at a different resolution to other
artists.
- get_texmanager(self)
- new_gc(self)
- Return an instance of a GraphicsContextBase
- points_to_pixels(self, points)
- Convert points to display units
points - a float or a numpy array of float
return points converted to pixels
You need to override this function (unless your backend doesn't have a
dpi, eg, postscript or svg).
Some imaging systems assume some value for pixels per inch.
points to pixels = points * pixels_per_inch/72.0 * dpi/72.0
- start_rasterizing(self)
- stop_rasterizing(self)
- strip_math(self, s)
