Pyqtgraph's Helper Functions
============================
Simple Data Display Functions
-----------------------------
.. autofunction:: pyqtgraph.plot
.. autofunction:: pyqtgraph.image
.. autofunction:: pyqtgraph.dbg
Color, Pen, and Brush Functions
-------------------------------
Qt uses the classes QColor, QPen, and QBrush to determine how to draw lines and fill shapes. These classes are highly capable but somewhat awkward to use. Pyqtgraph offers the functions :func:`~pyqtgraph.mkColor`, :func:`~pyqtgraph.mkPen`, and :func:`~pyqtgraph.mkBrush` to simplify the process of creating these classes. In most cases, however, it will be unnecessary to call these functions directly--any function or method that accepts *pen* or *brush* arguments will make use of these functions for you. For example, the following three lines all have the same effect::
pg.plot(xdata, ydata, pen='r')
pg.plot(xdata, ydata, pen=pg.mkPen('r'))
pg.plot(xdata, ydata, pen=QPen(QColor(255, 0, 0)))
