Found the way to load a QImage into the label on GraphicsLayoutWidget.
Cheers,
Vasilije
import pyqtgraph
app = pyqtgraph.QtGui.QApplication([])
win = pyqtgraph.GraphicsLayoutWidget()
qi = pyqtgraph.QtGui.QImage()
label = pyqtgraph.QtGui.QLabel(win)
qi.load('image.png')
label.setPixmap(pyqtgraph.QtGui.QPixmap.fromImage(qi))
win.show()
if __name__ == '__main__':
import sys
if (sys.flags.interactive != 1) or not hasattr(QtCore, 'PYQT_VERSION'):
pyqtgraph.QtGui.QApplication.instance().exec_()
