Jun 17, 2020 · The recommended way of plotting data from a file is therefore to use dedicated functions such as numpy.loadtxt or pandas.read_csv to read the data. These are more powerful and faster. Then plot the obtained data using matplotlib. Note that pandas.DataFrame.plot is a convenient wrapper around Matplotlib to create simple plots.

First, we'll use the built-in csv module to load CSV files, then we'll show how to utilize NumPy, which is a third-party module, to load files. import csv. plots = csv.reader(csvfile, delimiter=',') for row in plots: . x.append(int(row[0])) . y.append(int(row[1])) . plt.plot(x,y, label='Loaded from file!')

I've used matplotlib for plotting some experimental results (discussed it in here: Looping over files and plotting. However, saving the picture by clicking right to the image gives very bad quality / low resolution images. # read file, skip header (1 line) and unpack into 3 variables. WL, ABS, T = np.genfromtxt(fname, skip_header=1, unpack=True)

If you want to plot x and y using matplotlib, I suggest to change the format from 'str' to 'int' or 'float': import matplotlib.pyplot as plt with open('filename.txt', 'r') as f: lines = f.readlines() x = [float(line.split()[0]) for line in lines] y = [float(line.split()[1]) for line in lines] plt.plot(x ,y) plt.show()

Save the current figure as an image or vector graphic to a file. The available output formats depend on the backend being used. A path, or a Python file-like object, or possibly some backend-dependent object such as matplotlib.backends.backend_pdf.PdfPages. If format is set, it determines the output format, and the file is saved as fname.
