class GraphicsLayoutWidget(GraphicsView):

|
|
Convenience class consisting of a :class:`GraphicsView
|
|
<pyqtgraph.GraphicsView>` with a single :class:`GraphicsLayout
|
|
<pyqtgraph.GraphicsLayout>` as its central item.
|
|
|
|
This widget is an easy starting point for generating multi-panel figures.
|
|
Example::
|
|
|
|
w = pg.GraphicsLayoutWidget()
|
|
p1 = w.addPlot(row=0, col=0)
|
|
p2 = w.addPlot(row=0, col=1)
|
|
v = w.addViewBox(row=1, col=0, colspan=2)
|
|
|
|
Parameters
|
|
----------
|
|
parent : QWidget or None
|
|
The parent widget (see QWidget.__init__)
|
|
show : bool
|
|
If True, then immediately show the widget after it is created.
|
|
If the widget has no parent, then it will be shown inside a new window.
|
|
size : (width, height) tuple
|
|
Optionally resize the widget. Note: if this widget is placed inside a
|
|
layout, then this argument has no effect.
|
|
title : str or None
|
|
If specified, then set the window title for this widget.
|
|
kargs :
|
|
All extra arguments are passed to
|
|
:func:`GraphicsLayout.__init__() <pyqtgraph.GraphicsLayout.__init__>`
|
|
|
|
|
|
This class wraps several methods from its internal GraphicsLayout:
|
|
:func:`nextRow <pyqtgraph.GraphicsLayout.nextRow>`
|
|
:func:`nextColumn <pyqtgraph.GraphicsLayout.nextColumn>`
|
|
:func:`addPlot <pyqtgraph.GraphicsLayout.addPlot>`
|
|
:func:`addViewBox <pyqtgraph.GraphicsLayout.addViewBox>`
|
|
:func:`addItem <pyqtgraph.GraphicsLayout.addItem>`
|
|
:func:`getItem <pyqtgraph.GraphicsLayout.getItem>`
|
|
:func:`addLabel <pyqtgraph.GraphicsLayout.addLabel>`
|
|
:func:`addLayout <pyqtgraph.GraphicsLayout.addLayout>`
|
|
:func:`removeItem <pyqtgraph.GraphicsLayout.removeItem>`
|
|
:func:`itemIndex <pyqtgraph.GraphicsLayout.itemIndex>`
|
|
:func:`clear <pyqtgraph.GraphicsLayout.clear>`
