I have little experience how to combine matplotlib with tkinter or pyqt. I need a horizontal scroll bar on the matplotlib chart. I want to zoom the graph horizontally and scroll the graph from the beginning to the end of the data that is loaded from the file. After reviewing the examples, I added a scroll bar. But she's completely unresponsive to the chart.)
And the process doesn't end when I close the window(how to remove not understood, an example taken from here enter link)
import tkinter from tkinter import * from matplotlib.backends.backend_tkagg import ( FigureCanvasTkAgg, NavigationToolbar2Tk) import matplotlib.pyplot as plt import pandas as pd import numpy as np root = tkinter.Tk() x = pd.read_csv('file.txt', index_col='DATE', parse_dates=True, infer_datetime_format=True) z = x.iloc[:, 3].values N = len(z) ind = np.arange(N) fig, ax = plt.subplots() ax.plot(ind, z) canvas = FigureCanvasTkAgg(fig, master=root) canvas.show() canvas.get_tk_widget().pack(side=tkinter.TOP, fill=tkinter.BOTH, expand=1) toolbar = NavigationToolbar2Tk(canvas, root) toolbar.update() canvas.get_tk_widget().pack(side=tkinter.TOP, fill=tkinter.BOTH, expand=1) scrollbar = tkinter.Scrollbar(master=root, orient=HORIZONTAL) scrollbar.pack(side=tkinter.BOTTOM, fill=X) tkinter.mainloop() After adding a row
scrollbar["command"] = canvas.get_tk_widget().xview As pointed out- MaxiMouse. The graph scrolls, but not along the entire length. I need the scroll to work on all the data after zooming in. I displayed this at the end of the video.
