hi,

I need to add a lot of plots to a GraphicsLayoutWidget. But only the top several plots displays. Can i add a scollbar to the GraphicsLayoutWidget, then i can see all the plots.

how can I.

You can embed any widget inside a QScrollArea: https://qt-project.org/doc/qt-4.8/qscrollarea.html

For example:

import pyqtgraph as pg                                                                                                                                        

app = pg.mkQApp()                                                                                                                                

sa = pg.QtGui.QScrollArea()                                                                                                                                

w = pg.GraphicsLayoutWidget()                                                                                                                      

w.setFixedHeight(2000)

sa.setWidget(w)

for i in range(20):

  w.addPlot(row=i, col=0)

sa.show()

Thank you for this hint. I was looking for the same thing. But now I have the Scrollbar but the GraphicsLayoutWidget does not occupy the whole area in the Window. Is there a way to set minimum Sizes to the Items in the GraphcalLayoutWidget?

The QScrollArea documentation discusses this a little:  http://qt-project.org/doc/qt-4.8/qscrollarea.html

The first thing I would try is call setFixedHeight / setFixedWidth on the GraphicsLayoutWidget.
