In this article we will see how we can set 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.
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
setWindowTitlemethod with the plot window objectSyntax : window.setWindowTitle(title)
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 = "Lazyroar 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) # 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_() |
