Title
Body
I'm using pyqtgraph and I'd like to add an item in the legend for InfiniteLines. I've adapted the example code to demonstrate: # -*- coding: utf-8 -*- """ Demonstrates basic use of LegendItem """ import initExample ## Add path to library (just for examples; you do not need this) import pyqtgraph as pg from pyqtgraph.Qt import QtCore, QtGui plt = pg.plot() plt.setWindowTitle('pyqtgraph example: Legend') plt.addLegend() c1 = plt.plot([1,3,2,4], pen='r', name='red plot') c2 = plt.plot([2,1,4,3], pen='g', fillLevel=0, fillBrush=(255,255,255,30), name='green plot') c3 = plt.addLine(y=4, pen='y') # TODO: add legend item indicating "maximum value" ## Start Qt event loop unless running in interactive mode or using pyside. if __name__ == '__main__': import sys if (sys.flags.interactive != 1) or not hasattr(QtCore, 'PYQT_VERSION'): QtGui.QApplication.instance().exec_() What I get as a result is: How do I add an appropriate legend item?
