Hi,

I don't know if this is the best way to do it, but something like this 
works for axis labels:

self.plot = self.addPlot()
self.plot.setLabels(left="Left axis")
font = self.plot.getAxis("left").label.font()
font.setFamily("Serif")
self.plot.getAxis("left").label.setFont(font)
self.plot.getAxis("left").setTickFont(font)

For other items, you may need to do something similar, but look at the code 
to see what the QtGui.QGraphicsTextItem is called. For example, for a 
TextItem 
(http://www.pyqtgraph.org/documentation/_modules/pyqtgraph/graphicsItems/TextItem.html#TextItem)
 
you would use t.textItem.font() and t.textItem.setFont().
