PyQtGraph – Getting Title of Plot Window
  • Last Updated : 24 Sep, 2020

In this article we will see how we can get title to the plot window in the PyQtGraph module. PyQtGraph is a graphics and user interface library for Python that provides functionality commonly required in designing and science applications. Its primary goals are to provide fast, interactive graphics for displaying data (plots, video, etc.) and second is to provide tools to aid in rapid application development (for example, property trees such as used in Qt Designer).Plot windows consist of two main parts: the Plot Panel containing the actual plotted graphics and the Control Panel. Title is basically the name or caption of the plot window, it is displayed on the top left corner of the window. It can be set with the help of setWindowTitle method.

We can create a plot window with the help of command given below

# creating a pyqtgraph plot window
window = pg.plot()

In order to do this we use windowTitle method with the plot window object

Syntax : window.windowTitle()

Argument : It takes string as argument



Return : It returns None

Below is the implementation




# importing pyqtgraph as pg
import pyqtgraph as pg
  
# importing QtCore and QtGui from the pyqtgraph module
from pyqtgraph.Qt import QtCore, QtGui
  
# importing numpy as np
import numpy as np
  
import time
  
# creating a pyqtgraph plot window
window = pg.plot()
  
# setting window geometry
# left = 100, top = 100
# width = 600, height = 500
window.setGeometry(100, 100, 600, 500)
  
# title for the plot window
title = "GeeksforGeeks PyQtGraph"
  
# setting window title to plot window
window.setWindowTitle(title)
  
# create list for y-axis
y1 = [5, 5, 7, 10, 3, 8, 9, 1, 6, 2]
  
# create horizontal list i.e x-axis
x = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
  
# create pyqt5graph bar graph item 
# with width = 0.6
# with bar colors = green
bargraph1 = pg.BarGraphItem(x = x, height = y1, width = 0.6, brush ='g')
  
# add item to plot window
# adding bargraph item to the window
window.addItem(bargraph1)
  
# getting widnow title
value = window.windowTitle()
  
# printing value
print("Window Title : ", end ="")
print(value)
  
  
  
# main method
if __name__ == '__main__':
      
    # importing system
    import sys
      
    # Start Qt event loop unless running in interactive mode or using 
    if (sys.flags.interactive != 1) or not hasattr(QtCore, 'PYQT_VERSION'):
        QtGui.QApplication.instance().exec_()
         

Output :

Window Title : GeeksforGeeks PyQtGraph
