<h1>Interactive navigation<a class="headerlink" href="#interactive-navigation" title="Permalink to this headline">¶</a></h1>

All figure windows come with a navigation toolbar, which can be used

to navigate through the data set. Here is a description of each of

the buttons at the bottom of the toolbar

<dt>The <code class="docutils literal notranslate">Home</code>, <code class="docutils literal notranslate">Forward</code> and <code class="docutils literal notranslate">Back</code> buttons</dt>

<dd>These are akin to a web browser's home, forward and back controls.

<code class="docutils literal notranslate">Forward</code> and <code class="docutils literal notranslate">Back</code> are used to navigate back and forth between

previously defined views. They have no meaning unless you have already

navigated somewhere else using the pan and zoom buttons. This is analogous

to trying to click <code class="docutils literal notranslate">Back</code> on your web browser before visiting a

new page or <code class="docutils literal notranslate">Forward</code> before you have gone back to a page --

nothing happens. <code class="docutils literal notranslate">Home</code> always takes you to the

first, default view of your data. Again, all of these buttons should

feel very familiar to any user of a web browser.</dd>

</dl>

<dt>The <code class="docutils literal notranslate">Pan/Zoom</code> button</dt>

<dd>This button has two modes: pan and zoom. Click the toolbar button

to activate panning and zooming, then put your mouse somewhere

over an axes. Press the left mouse button and hold it to pan the

figure, dragging it to a new position. When you release it, the

data under the point where you pressed will be moved to the point

where you released. If you press 'x' or 'y' while panning the

motion will be constrained to the x or y axis, respectively. Press

the right mouse button to zoom, dragging it to a new position.

The x axis will be zoomed in proportionately to the rightward

movement and zoomed out proportionately to the leftward movement.

The same is true for the y axis and up/down motions. The point under your

mouse when you begin the zoom remains stationary, allowing you to

zoom in or out around that point as much as you wish. You can use the

modifier keys 'x', 'y' or 'CONTROL' to constrain the zoom to the x

axis, the y axis, or aspect ratio preserve, respectively.

With polar plots, the pan and zoom functionality behaves

differently. The radius axis labels can be dragged using the left

mouse button. The radius scale can be zoomed in and out using the

right mouse button.

</dd>

</dl>

<dt>The <code class="docutils literal notranslate">Zoom-to-rectangle</code> button</dt>

<dd>Click this toolbar button to activate this mode. Put your mouse somewhere

over an axes and press a mouse button. Define a rectangular region by

dragging the mouse while holding the button to a new location. When using

the left mouse button, the axes view limits will be zoomed to the defined

region. When using the right mouse button, the axes view limits will be

zoomed out, placing the original axes in the defined region.</dd>

</dl>

<dt>The <code class="docutils literal notranslate">Subplot-configuration</code> button</dt>

<dd>Use this tool to configure the appearance of the subplot:

you can stretch or compress the left, right, top, or bottom

side of the subplot, or the space between the rows or

space between the columns.</dd>

</dl>

<dt>The <code class="docutils literal notranslate">Save</code> button</dt>

<dd>Click this button to launch a file save dialog. You can save

files with the following extensions: <code class="docutils literal notranslate">png</code>, <code class="docutils literal notranslate">ps</code>, <code class="docutils literal notranslate">eps</code>,

</dl>

<h2>Navigation Keyboard Shortcuts<a class="headerlink" href="#navigation-keyboard-shortcuts" title="Permalink to this headline">¶</a></h2>

If you are using <a class="reference internal" href="../api/_as_gen/matplotlib.pyplot.html#module-matplotlib.pyplot" title="matplotlib.pyplot"><code class="xref py py-mod docutils literal notranslate">matplotlib.pyplot</code></a> the toolbar will be created

automatically for every figure. If you are writing your own user

interface code, you can add the toolbar as a widget. The exact syntax

depends on your UI, but we have examples for every supported UI in the

<code class="docutils literal notranslate">matplotlib/examples/user_interfaces</code> directory. Here is some

example code for GTK+ 3:

<div class="highlight-default notranslate"><div class="highlight"><pre>import gi

gi.require_version('Gtk', '3.0')

from gi.repository import Gtk

from matplotlib.figure import Figure

from matplotlib.backends.backend_gtk3agg import FigureCanvas

from matplotlib.backends.backend_gtk3 import (

NavigationToolbar2GTK3 as NavigationToolbar)

win = Gtk.Window()

win.connect("destroy", lambda x: Gtk.main_quit())

win.set_default_size(400,300)

win.set_title("Embedding in GTK")

vbox = Gtk.VBox()

win.add(vbox)

fig = Figure(figsize=(5,4), dpi=100)

ax = fig.add_subplot(111)

ax.plot([1,2,3])

canvas = FigureCanvas(fig) # a Gtk.DrawingArea

vbox.pack_start(canvas, True, True, 0)

toolbar = NavigationToolbar(canvas, win)

vbox.pack_start(toolbar, False, False, 0)

win.show_all()

Gtk.main()
