Hi Patrick,
Setting the z value of the axes items worked as you suggested. However, the
grid is now rendered on top of the plotted curve. Do you have an idea of
how to render the curve on top?
I have tried setting the z value of the curve but this doesn't seem to help.
self.viewbox.setBackgroundColor((192,192,192))
self.myplot.getAxis("bottom").setPen({"color": (255, 255, 255), "width": 5})
self.myplot.getAxis("left").setPen({"color": (255, 255, 255), "width": 5})
for k in ['bottom', 'left']:
axis = self.myplot.getAxis(k)
axis.setZValue(1)
curve = self.myplot.plot(self.xdata, self.ydata, pen=MYPEN)
curve.setZValue(1e6) #this doesn't help
