pyqtgraph example

Sure! Here is a simple example of using PyQtGraph to create a basic plot:

import pyqtgraph as pg
from pyqtgraph.Qt import QtGui, QtCore
import numpy as np

# Create the data
x = np.linspace(0, 10, 100)
y = np.sin(x)

# Create the application and main window
app = QtGui.QApplication([])
win = pg.GraphicsWindow(title="PyQtGraph Example")
win.resize(800, 600)

# Create a plot widget within the main window
plot = win.addPlot(title="Plotting Example")
plot.addLegend()

# Plot the data
plot.plot(x, y, pen='r', name='sin(x)')

# Customize the plot appearance
plot.setLabel('left', 'Amplitude', units='V')
plot.setLabel('bottom', 'Time', units='s')

# Enable grid
plot.showGrid(x=True, y=True)

# Start the Qt event loop
if __name__ == '__main__':
    QtGui.QApplication.instance().exec_()

This example demonstrates how to create a PyQtGraph application, add a plot widget to the main window, plot some data, and customize the appearance of the plot. You can run this code to see a simple sine wave plot with grid lines.
