Hello
In pyqtgraph docoment, it says that one plotDataItem object can have
multiple curves. I tried to implemented but it did not work.
here is the code
import pyqtgraph as pg
from pyqtgraph.Qt import QtCore, QtGui
import numpy as np
pg.setConfigOption('background', 'w')
pg.mkQApp()
pw = pg.PlotWidget()
pw.show()
p1 = pw.plotItem
c = pg.PlotCurveItem([{'x': [1,2,3], 'y': [11,22,33]}, {'x': [1,2,3], 'y':
[11,22,33]}])
p1.addItem(c)
if __name__ == '__main__':
import sys
if (sys.flags.interactive != 1) or not hasattr(QtCore, 'PYQT_VERSION'):
QtGui.QApplication.instance().exec_()
