PyQtGraph grid with linked axes

Having a simple graphics layout with PyQtGraph in which the x-axis of the plots are linked together and the grid is displayed in both plots as well: ``` from pyqtgraph.Qt import QtGui, QtCore import pyqtgraph as pg app = QtGui.QApplication([]) view = pg.GraphicsView() l = pg.GraphicsLayout() view.setCentralItem(l) view.show() view.resize(800,600) p0 = l.addPlot(0, 0) p0.showGrid(x = True, y = True, alpha = 0.3) #p0.hideAxis('bottom') p1 = l.addPlot(1, 0) p1.showGrid(x = True, y = True, alpha = 0.3) p1.setXLink(p0) l.layout.setSpacing(0.) l.setContentsMargins(0., 0., 0., 0.) if __name__ == '__main__': import sys if (sys.flags.interactive != 1) or not hasattr(QtCore, 'PYQT_VERSION'): QtGui.QApplication.instance().exec_() ``` If I hide the x-axis in the first plot (uncommenting the `p0.hideAxis('bottom')` line in the code) then the axis will be gone, but the grid will disappear too: How could I force it to stay there? As both x-axis are linked together, I would expect that to be possible (the grid in the upper plot could be taken from the lower plot's x-axis).
