matplotlib.widgets#

GUI neutral widgets#

Widgets that are designed to work for any of the GUI backends. All of these widgets require you to predefine a matplotlib.axes.Axes instance and pass that as the first parameter. Matplotlib doesn't try to be too smart with respect to layout -- you will have to figure out how wide and tall you want your Axes to be to accommodate your widget.

class matplotlib.widgets.AxesWidget(ax)[source]#

Bases: matplotlib.widgets.Widget

Widget connected to a single Axes.

To guarantee that the widget remains responsive and not garbage-collected, a reference to the object should be maintained by the user.

This is necessary because the callback registry maintains only weak-refs to the functions, which are member functions of the widget. If there are no references to the widget object it may be garbage collected which will disconnect the callbacks.

Attributes

axAxes: The parent axes for the widget.
canvasFigureCanvasBase: The parent figure canvas for the widget.
activebool: Is the widget active?

property cids[source]#

connect_event(event, callback)[source]#

Connect a callback function with an event.

This should be used in lieu of figure.canvas.mpl_connect since this function stores callback ids for later clean up.

disconnect_events()[source]#: Disconnect all events created by this widget.

class matplotlib.widgets.Button(ax, label, image=None, color='0.85', hovercolor='0.95')[source]#

Bases: matplotlib.widgets.AxesWidget

A GUI neutral button.

For the button to remain responsive you must keep a reference to it. Call on_clicked to connect to the button.

Attributes

ax: The matplotlib.axes.Axes the button renders into.
label: A matplotlib.text.Text instance.
color: The color of the button when not hovering.
hovercolor: The color of the button when hovering.

Parameters

axAxes: The Axes instance the button will be placed into.
labelstr: The button text.
imagearray-like or PIL Image: The image to place in the button, if not None. The parameter is directly forwarded to imshow.
colorcolor: The color of the button when not activated.
hovercolorcolor: The color of the button when the mouse is over it.

property cnt[source]#

disconnect(cid)[source]#: Remove the callback function with connection id cid.

property observers[source]#

on_clicked(func)[source]#

Connect the callback function func to button click events.

Returns a connection id, which can be used to disconnect the callback.

class matplotlib.widgets.CheckButtons(ax, labels, actives=None)[source]#

Bases: matplotlib.widgets.AxesWidget

A GUI neutral set of check buttons.

For the check buttons to remain responsive you must keep a reference to this object.

Connect to the CheckButtons with the on_clicked method.

Attributes

axAxes: The parent axes for the widget.
labelslist of Text
rectangleslist of Rectangle
lineslist of (Line2D, Line2D) pairs: List of lines for the x's in the check boxes. These lines exist for each box, but have set_visible(False) when its box is not checked.

Add check buttons to matplotlib.axes.Axes instance ax.

Parameters

axAxes: The parent axes for the widget.
labelslist of str: The labels of the check buttons.
activeslist of bool, optional: The initial check states of the buttons. The list must have the same length as labels. If not given, all buttons are unchecked.

property cnt[source]#

disconnect(cid)[source]#: Remove the observer with connection id cid.

get_status()[source]#: Return a tuple of the status (True/False) of all of the check buttons.

property observers[source]#

on_clicked(func)[source]#

Connect the callback function func to button click events.

Returns a connection id, which can be used to disconnect the callback.

set_active(index)[source]#

property draw_shape[source]#

class matplotlib.widgets.Lasso(ax, xy, callback=None, useblit=True)[source]#

Bases: matplotlib.widgets.AxesWidget

Selection curve of an arbitrary shape.

The selected path can be used in conjunction with contains_point to select data points from an image.

Unlike LassoSelector, this must be initialized with a starting point xy, and the Lasso events are destroyed upon release.

Parameters

axAxes: The parent axes for the widget.
xy(float, float): Coordinates of the start of the lasso.
useblitbool, default: True: Whether to use blitting for faster drawing (if supported by the backend).
callbackcallable: Whenever the lasso is released, the callback function is called and passed the vertices of the selected path.

onmove(event)[source]#

onrelease(event)[source]#

class matplotlib.widgets.LassoSelector(ax, onselect=None, useblit=True, props=None, button=None)[source]#

Bases: matplotlib.widgets._SelectorWidget

Selection curve of an arbitrary shape.

For the selector to remain responsive you must keep a reference to it.

The selected path can be used in conjunction with contains_point to select data points from an image.

In contrast to Lasso, LassoSelector is written with an interface similar to RectangleSelector and SpanSelector, and will continue to interact with the axes until disconnected.

Example usage:

ax = plt.subplot()
ax.plot(x, y)

def onselect(verts):
    print(verts)
lasso = LassoSelector(ax, onselect)

Parameters

axAxes: The parent axes for the widget.
onselectfunction: Whenever the lasso is released, the onselect function is called and passed the vertices of the selected path.
useblitbool, default: True: Whether to use blitting for faster drawing (if supported by the backend).
propsdict, optional: Properties with which the line is drawn, see matplotlib.lines.Line2D for valid properties. Default values are defined in mpl.rcParams.
buttonMouseButton or list of MouseButton, optional: The mouse buttons used for rectangle selection. Default is None, which corresponds to all buttons.

Notes

Deprecated since version 3.5: Use press instead.

onrelease(event)[source]#

[Deprecated]

Notes

Deprecated since version 3.5: Use release instead.

class matplotlib.widgets.LockDraw[source]#

Bases: object

Some widgets, like the cursor, draw onto the canvas, and this is not desirable under all circumstances, like when the toolbar is in zoom-to-rect mode and drawing a rectangle. To avoid this, a widget can acquire a canvas' lock with canvas.widgetlock(widget) before drawing on the canvas; this will prevent other widgets from doing so at the same time (if they also try to acquire the lock first).

available(o)[source]#: Return whether drawing is available to o.

isowner(o)[source]#: Return whether o owns this lock.

locked()[source]#: Return whether the lock is currently held by an owner.

release(o)[source]#: Release the lock from o.

class matplotlib.widgets.MultiCursor(canvas, axes, useblit=True, horizOn=False, vertOn=True, **lineprops)[source]#

Bases: matplotlib.widgets.Widget

Provide a vertical (default) and/or horizontal line cursor shared between multiple axes.

For the cursor to remain responsive you must keep a reference to it.

Parameters

canvasmatplotlib.backend_bases.FigureCanvasBase: The FigureCanvas that contains all the axes.
axeslist of matplotlib.axes.Axes: The Axes to attach the cursor to.
useblitbool, default: True: Use blitting for faster drawing if supported by the backend.
horizOnbool, default: False: Whether to draw the horizontal line.
vertOn: bool, default: True: Whether to draw the vertical line.

Other Parameters

**lineprops: Line2D properties that control the appearance of the lines. See also axhline.

Examples

See Multicursor.

clear(event)[source]#: Clear the cursor.

connect()[source]#: Connect events.

disconnect()[source]#: Disconnect events.

onmove(event)[source]#

class matplotlib.widgets.PolygonSelector(ax, onselect, useblit=False, props=None, handle_props=None, grab_range=10)[source]#

Bases: matplotlib.widgets._SelectorWidget

Select a polygon region of an axes.

Place vertices with each mouse click, and make the selection by completing the polygon (clicking on the first vertex). Once drawn individual vertices can be moved by clicking and dragging with the left mouse button, or removed by clicking the right mouse button.

In addition, the following modifier keys can be used:

Hold ctrl and click and drag a vertex to reposition it before the polygon has been completed.
Hold the shift key and click and drag anywhere in the axes to move all vertices.
Press the esc key to start a new polygon.

For the selector to remain responsive you must keep a reference to it.

Parameters

axAxes: The parent axes for the widget.
onselectfunction: When a polygon is completed or modified after completion, the onselect function is called and passed a list of the vertices as (xdata, ydata) tuples.
useblitbool, default: False: Whether to use blitting for faster drawing (if supported by the backend).
propsdict, optional: Properties with which the line is drawn, see matplotlib.lines.Line2D for valid properties. Default:

dict(color='k', linestyle='-', linewidth=2, alpha=0.5)
handle_propsdict, optional: Artist properties for the markers drawn at the vertices of the polygon. See the marker arguments in matplotlib.lines.Line2D for valid properties. Default values are defined in mpl.rcParams except for the default value of markeredgecolor which will be the same as the color property in props.
grab_rangefloat, default: 10: A vertex is selected (to complete the polygon or to move a vertex) if the mouse click is within grab_range pixels of the vertex.

Notes

If only one point remains after removing points, the selector reverts to an incomplete state and you can start drawing a new polygon from the existing point.

Examples

Polygon Selector

property line[source]#

onmove(event)[source]#: Cursor move event handler and validator.

property vertex_select_radius[source]#

property verts#: The polygon vertices, as a list of (x, y) pairs.
