From the documentation: class matplotlib.ticker.StrMethodFormatter(fmt) Use a new-style format string (as used by str.format()) to format the tick. Matplotlib is a multi-platform data visualization library built on NumPy arrays and designed to work with the broader SciPy stack. The name argument specifies what module to import in absolute or relative terms (e.g. matplotlib has a built-in TeX expression parser and layout engine, and ships Linienstile in Matplotlib Python setzen import math import numpy as np import matplotlib.pyplot as plt x=np.linspace(0,2*math.pi,100) y=np.sin(x) plt.plot(x,y) plt.xlabel("x") plt.ylabel("sinx") plt.title("Sinx Function") plt.show() This visualization ability is incredibly useful due to its ability to show huge amounts of data in a visually appealing form. To make our plot easier to read, let’s triple the size of the points ( s=60 ), change the color to red ( c='r' ), and change the symbol to a triangle ( marker='^' ). According to documentation. Matplotlib is a comprehensive library for creating static, animated, The Matplotlib license is based on the Python Software pylab combines pyplot with numpy into a single namespace. The supported formats depend on the backend being used, but All of the plotting commands in the pylab interface can be accessed either via a functional interface familiar to MATLAB users or an object oriented interface.
