Pyqtgraph's Helper Functions
|
||
|
============================
|
||
|
|
||
|
Simple Data Display Functions
|
||
|
-----------------------------
|
||
|
|
||
|
.. autofunction:: pyqtgraph.plot
|
||
|
|
||
|
.. autofunction:: pyqtgraph.image
|
||
|
|
||
|
|
||
|
|
||
|
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)))
|
||
|
|
||
|
|
||
|
.. autofunction:: pyqtgraph.mkColor
|
||
|
|
||
|
.. autofunction:: pyqtgraph.mkPen
|
||
|
|
||
|
.. autofunction:: pyqtgraph.mkBrush
|
||
|
|
||
|
.. autofunction:: pyqtgraph.hsvColor
|
||
|
|
||
|
.. autofunction:: pyqtgraph.intColor
|
||
|
|
||
|
.. autofunction:: pyqtgraph.colorTuple
|
||
|
|
||
|
.. autofunction:: pyqtgraph.colorStr
|
||
|
|
||
|
|
||
|
Data Slicing
|
||
|
------------
|
||
|
|
||
|
.. autofunction:: pyqtgraph.affineSlice
|
||
|
|
||
|
|
||
|
|
||
|
SI Unit Conversion Functions
|
||
|
----------------------------
|
||
|
|
||
|
.. autofunction:: pyqtgraph.siFormat
|
||
|
|
||
|
.. autofunction:: pyqtgraph.siScale
|
||
|
|
||
|
.. autofunction:: pyqtgraph.siEval
|
||
|
