picker can be one of the following:<br>

None - picking is disabled for this artist (default)<br>
<br>
boolean - if True then picking will be enabled and the<br>
artist will fire a pick event if the mouse event is over<br>
the artist<br>
<br>
float - if picker is a number it is interpreted as an<br>
epsilon tolerance in points and the the artist will fire<br>
off an event if it's data is within epsilon of the mouse<br>
event. For some artists like lines and patch collections,<br>
the artist may provide additional data to the pick event<br>
that is generated, eg the indices of the data within<br>
epsilon of the pick event<br>
<br>
function - if picker is callable, it is a user supplied<br>
function which determines whether the artist is hit by the<br>
mouse event.<br>
<br>
hit, props = picker(artist, mouseevent)<br>
<br>
to determine the hit test. if the mouse event is over the<br>
artist, return hit=True and props is a dictionary of<br>
properties you want added to the PickEvent attributes<br>

<dl><dt><a name="-setp"><strong>setp</strong></a>(h, *args, **kwargs)</dt><dd><tt>matplotlib supports the use of setp ("set property") and getp to set<br>
and get object properties, as well as to do introspection on the<br>
object For example, to set the linestyle of a line to be dashed, you<br>
can do<br>
<br>
>>> line, = plot([1,2,3])<br>
>>> <a href="#-setp">setp</a>(line, linestyle='--')<br>
<br>
If you want to know the valid types of arguments, you can provide the<br>
name of the property you want to set without a value<br>
<br>
>>> <a href="#-setp">setp</a>(line, 'linestyle')<br>
linestyle: [ '-' | '--' | '-.' | ':' | 'steps' | 'None' ]<br>
<br>
If you want to see all the properties that can be set, and their<br>
possible values, you can do<br>
<br>
<br>
>>> <a href="#-setp">setp</a>(line)<br>
... long output listing omitted'<br>
<br>
setp operates on a single instance or a list of instances. If you<br>
are in query mode introspecting the possible values, only the first<br>
instance in the sequence is used. When actually setting values,<br>
all the instances will be set. Eg, suppose you have a list of two<br>
lines, the following will make both lines thicker and red<br>
<br>
>>> x = arange(0,1.0,0.01)<br>
>>> y1 = sin(2*pi*x)<br>
>>> y2 = sin(4*pi*x)<br>
>>> lines = plot(x, y1, x, y2)<br>
>>> <a href="#-setp">setp</a>(lines, linewidth=2, color='r')<br>
<br>
setp works with the matlab(TM) style string/value pairs or with<br>
python kwargs. For example, the following are equivalent<br>
<br>
>>> <a href="#-setp">setp</a>(lines, 'linewidth', 2, 'color', r') # matlab style<br>
>>> <a href="#-setp">setp</a>(lines, linewidth=2, color='r') # python style</tt></dd></dl>
