how to include characters in a diagram with matplotlib - atlass218 - Sep-20-2018 Hello; I created an application with which if I click on the button "save", there is creation of a text file in which I save data in columns. among these data there is the date in first colone here is the contents of the file (file.txt): 01/12/2010 ... 0.132 02/05/2011 ... 0.186 28/12/2011 ... 0.168 04/06/2012 ... 0.122 29/12/2012 ... 0.144 06/06/2013 ... 0.112 07/01/2014 ... 0.186 08/06/2014 ... 0.168 19/12/2014 ... 0.152 10/06/2015 ... 0.164 this content is not fixed since each time you click on the save button a new line is added to the text file import numpy as np import matplotlib.pyplot as plt def graphe_loc35R(): x,y = np.loadtxt("file.txt", unpack=True) plt.plot(x,y,'o') plt.xlabel('date') plt.ylabel('ddm') plt.show()I would like help to find out how to include characters in the x-axis of a diagram built with matpltlib thanks RE: how to include characters in a diagram with matplotlib - Mekire - Sep-20-2018 Quote:I would like help to find out how to include characters in the x-axis of a diagram built with matpltlibSo you want the date labels on the X-axis? If so you are going to want the xticks function.Something like: plt.xticks(x_values, labels, rotation=30) RE: how to include characters in a diagram with matplotlib - atlass218 - Sep-20-2018 hello; but this code is for limited number of values. at my text file (file.txt), the number of line is not fixed and il will be modify each time a personn click on save button RE: how to include characters in a diagram with matplotlib - Mekire - Sep-21-2018 It can absolutely work. Load the dates into a variable named labels anytime it changes and update your xticks .
