I am trying to build a GUI app for graph plotting where graph can be shown as a slideshow so that the data can be clearly visualised. First I wish to plot a set of data then after a specific time interval next set of data and so on.
I have a text file contains data as:
0.00 -10.742 10.7888 6.33455
1.00 -17.75391 10.0000 4.66778
4.00 -19.62891 15.9999 4.232323
20.00 -20.7641 18.6666 3.99999
23.00 -34.2300 2.7777 2.00000
50.00 -50.000 1.87878 2.77778
65.88 -22.5000 2.99999 1.45555
78.00 -30.000 1.55555 2.45667
86.00 -37.7900 2.55556 7.55679
90.00 -45.00000 13.6667 2.677888

200.02 200.01 0.0000 2.6667
300.00 300.02 1.6666 2.7878What I have tried is:
from PyQt5.QtWidgets import *
from PyQt5.uic import loadUi
from matplotlib.backends.backend_qt5agg import (NavigationToolbar2QT as NavigationToolbar)
import matplotlib.pyplot as plt
import numpy as np
from matplotlib import style
import os
class MatplotlibWidget(QMainWindow):
def __init__(self):
QMainWindow.__init__(self)
loadUi("graphgenerate.ui", self)
self.setWindowTitle("PyQt5 & Matplotlib Example GUI")
self.playbutton.clicked.connect(self.drawGraph)
self.addToolBar(NavigationToolbar(self.MplWidget.canvas, self))
def drawGraph(self):
f1 = open('TESTIP2.txt', 'r')
print(f1)
data = np.genfromtxt(f1)
m = np.size(data, 0)
n = np.size(data, 1)
x = data[:, 0].reshape(m, 1)
y = data[:, 1].reshape(m, 1)
iters = m // 4
xs=[]
ys=[]
for i in range(iters):
xs.append(x[i])
ys.append(y[i])
self.MplWidget.canvas.axes.clear()
self.MplWidget.canvas.axes.plot(xs,ys)
self.MplWidget.canvas.axes.legend(('cosinus', 'sinus'), loc='upper right')
self.MplWidget.canvas.axes.set_title('Signal' )
self.MplWidget.canvas.draw()
if __name__ == "__main__":
app = QApplication([])
window = MatplotlibWidget()
window.show()
app.exec_() Currently only first set of data is working . I wish to plot next set of data from same file after a specific time interval, say 10s. Likewise I am trying to show next and so on. Anyone please help me out there to fix this.
