Hi, I'm trying to plot data from a drone in an updating scrolling plot. For the plotting I use the example code number 3 from this file: https://github.com/pyqtgraph/pyqtgraph/blob/develop/examples/scrollingPlots.py
Now i want to be able to send commands to the drone while the plots keep updating, because that's the data that I want to see. Now I figured I need to multi thread using Qt, and got my code form here: https://groups.google.com/forum/#!topic/pyqtgraph/haiJsGhxTaQ But when I start the thread the main thread sleeps. I'm new to this and have no idea what's happening, can someone help me? Without the the threading the plots work just fine. This is my code: import pyqtgraph as pg import time from pyqtgraph.Qt import QtCore, QtGui import numpy as np from pyardrone import ARDrone, at import thread1 ## Code for plot, copied form example. -- ## Threading and updating part def update(): print("update") update_plot_vx() update_plot_vy() update_plot_vz() class Thread(pg.QtCore.QThread): newData = pg.QtCore.Signal(object) def run(self): thread1 timer = pg.QtCore.QTimer() timer.timeout.connect(update) timer.start(50) thread = Thread() thread.newData.connect(update) #It might be something with row, but removing it doesn't change anything thread.start() # 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_() -- You received this message because you are subscribed to the Google Groups "pyqtgraph" group.
