The basicpanel module
A resuable panel for displaying graphs.
This module provides a panel which can be used in frames to display graphs to
the user. It uses matplotlib, and it probably is not the fastest (as in
processing speed) way to implement this, but it works for the most part.
Classes
GraphPanel

class src.gui.graphing.basicpanel.GraphPanel(parent, labels, title=None, dataQueue=None)[source]

| Parameters : | data : 6-tuple of float
A tuple which consists of the following values (all floats) in
order:
- the x-value of the point to add,
- the y-value of the point to add,

-
toggleUpdates(event=None)[source]
