GraphicsLayoutWidget

class pyqtgraph.GraphicsLayoutWidget(parent=None, show=False, size=None, title=None, **kargs)

Convenience class consisting of a GraphicsView with a single 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)

parentQWidget or None

The parent widget (see QWidget.__init__)

showbool

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.

titlestr or None

If specified, then set the window title for this widget.

kargs

All extra arguments are passed to GraphicsLayout.__init__()

This class wraps several methods from its internal GraphicsLayout: nextRow nextColumn addPlot addViewBox addItem getItem addLabel addLayout removeItem itemIndex clear

__init__(parent=None, show=False, size=None, title=None, **kargs)

Arguments:
parent	Optional parent widget
useOpenGL	If True, the GraphicsView will use OpenGL to do all of its rendering. This can improve performance on some systems, but may also introduce bugs (the combination of QGraphicsView and QGLWidget is still an ‘experimental’ feature of Qt)
background	Set the background color of the GraphicsView. Accepts any single argument accepted by mkColor. By default, the background color is determined using the ‘backgroundColor’ configuration option (see setConfigOptions).
