To All,
Thank you for any assistance. I am new to programming.
When I create a simple code, my Plotwidget displays a graph where the data
does not match the axis and axis do not even intersect. Nothing I do to the
code seems to fix it.
I installed Python 3.8
I just installed PyQt5 following the instructions at the Riverbank site
using windows powershell and PIP.
Windows10
Using VSCode.
Anyways, anybody know whats going on and how to fix it. I was having fun
with python PyQt5 as it was doing a lot of what I wanted but I noticed when
I use the plotwidget() I get this behavior.
Is it better implement MatplotLib instead of plotwidget() and put it into a
QWidget? Basically, I would like to build a realtime graph with temperature
data. There seems to be a million ways to do this.
//CODE
from PyQt5 import QtWidgets, uic
from pyqtgraph import PlotWidget, plot
import pyqtgraph as pg
import sys # We need sys so that we can pass argv to QApplication
import os
class MainWindow(QtWidgets.QMainWindow):
def __init__(self, *args, **kwargs):
super(MainWindow, self).__init__(*args, **kwargs)
self.graphWidget = pg.PlotWidget()
self.setCentralWidget(self.graphWidget)
hour = [1,2,3,4,5,6,7,8,9,10]
temperature = [30,32,34,32,33,31,29,32,35,45]
# plot data: x, y values
self.graphWidget.plot(hour, temperature)
def main():
app = QtWidgets.QApplication(sys.argv)
main = MainWindow()
main.show()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
//Code
