Matplotlib (portmanteau of MATLAB, plot, and library [3]) is a plotting library for the Python programming language and its numerical mathematics extension NumPy.It provides an object-oriented API for embedding plots into applications using general-purpose GUI toolkits like Tkinter, wxPython, Qt, or GTK.
The Mandelbrot set within a continuously colored environment. The Mandelbrot set (/ ˈ m æ n d əl b r oʊ t,-b r ɒ t /) [1] [2] is a two-dimensional set with a relatively simple definition that exhibits great complexity, especially as it is magnified.

In 1981, Bernhard Flury and Hans Riedwyl suggested "asymmetrical" Chernoff faces; [3] since a face has vertical symmetry (around the y axis), the left side of the face is identical to the right and is basically wasted space – a point also made by Tufte. [4]
Python and Matplotlib are cross-platform, and are therefore available for Windows, OS X, and the Unix-like operating systems like Linux and FreeBSD. Matplotlib can create plots in a variety of output formats, such as PNG and SVG. Matplotlib mainly does 2-D plots (such as line, contour, bar, scatter, etc.), but 3-D functionality is also available.
This figure was produced by Leland McInnes using python and matplotlib and is licensed under the GFDL. All data is from publicly available sources. All data is from publicly available sources. The plot can likely be updated for more recent data using these same script, though minor modifications may be required for changes in data formats ...
Some features of convolution are similar to cross-correlation: for real-valued functions, of a continuous or discrete variable, convolution () differs from cross-correlation only in that either () or () is reflected about the y-axis in convolution; thus it is a cross-correlation of () and (), or () and ().
A Python 3 based simulation using Matplotlib to sketch Buffon's needle experiment with the parameters t = 5.0, l = 2.6. Observe the calculated value of π (y-axis) approaching 3.14 as the number of tosses (x-axis) approaches infinity. In the first, simpler case above, the formula obtained for the probability P can be rearranged to
