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.</p>

Drawing a line would result in a line from vertex A to vertex C in
a rectangle ABCD.</p>
<p><em>spancoords</em> is one of 'data' or 'pixels'. If 'data', <em>minspanx</em>
and <em>minspanx</em> will be interpreted in the same coordinates as
the x and y axis. If 'pixels', they are in pixels.</p>
<p><em>button</em> is a list of integers indicating which mouse buttons should
be used for rectangle selection. You can also specify a single
integer if only a single button is desired. Default is <em>None</em>,
which does not limit which button can be used.</p>
<dl class="docutils">

<p><em>interactive</em> will draw a set of handles and allow you interact
with the widget after it is drawn.</p>
<p><em>state_modifier_keys</em> are keyboard modifiers that affect the behavior
of the widget.</p>
<p>The defaults are:
dict(move=' ', clear='escape', square='shift', center='ctrl')</p>
<p>Keyboard modifiers, which:
'move': Move the existing shape.
'clear': Clear the current shape.
'square': Makes the shape square.
'center': Make the initial point the center of the shape.
'square' and 'center' can be combined.</p>

<p>Use <em>drawtype</em> if you want the mouse to draw a line,
a box or nothing between click and actual position by setting</p>
<p><code class="docutils literal notranslate"><span class="pre">drawtype</span> <span class="pre">=</span> <span class="pre">'line'</span></code>, <code class="docutils literal notranslate"><span class="pre">drawtype='box'</span></code> or <code class="docutils literal notranslate"><span class="pre">drawtype</span> <span class="pre">=</span> <span class="pre">'none'</span></code>.
Drawing a line would result in a line from vertex A to vertex C in
a rectangle ABCD.</p>
<p><em>spancoords</em> is one of 'data' or 'pixels'. If 'data', <em>minspanx</em>
and <em>minspanx</em> will be interpreted in the same coordinates as
the x and y axis. If 'pixels', they are in pixels.</p>
<p><em>button</em> is a list of integers indicating which mouse buttons should
be used for rectangle selection. You can also specify a single
integer if only a single button is desired. Default is <em>None</em>,
which does not limit which button can be used.</p>
<dl class="docutils">
<dt>Note, typically:</dt>
<dd>1 = left mouse button
2 = center mouse button (scroll wheel)
3 = right mouse button</dd>

<p><em>interactive</em> will draw a set of handles and allow you interact
with the widget after it is drawn.</p>
<p><em>state_modifier_keys</em> are keyboard modifiers that affect the behavior
of the widget.</p>
<p>The defaults are:
dict(move=' ', clear='escape', square='shift', center='ctrl')</p>
<p>Keyboard modifiers, which:
'move': Move the existing shape.
'clear': Clear the current shape.
'square': Makes the shape square.
'center': Make the initial point the center of the shape.
'square' and 'center' can be combined.</p>
