Before we start: This Python tutorial is a part of our series of Python Package tutorials. You can find other Matplotlib related topics too! Pythonistas typically use the Matplotlib plotting library to display numeric data in plots, graphs and charts in Python. The pyplot interface is easier to implement than the OO version and is more commonly used. For information about pyplot functions and terminology, refer to: What is Pyplot in Matplotlib. The matplotlib. The simplest example uses the plot function to plot values as x,y coordinates in a data plot. In this case, plot takes 2 parameters for specifying plot coordinates:. Figure 1. A simple plot created with the plot function:. A partial list of string characters that are acceptable options for marker and linestyle :. Matplotlib also supports more advanced plots, such as scatter plots. In this case, the scatter function is used to display data values as a collection of x,y coordinates represented by standalone dots. In this example, 2 arrays of the same length one array for X axis values and another array for Y axis values are plotted.

You can clear the current figure with clf and the current axes with cla, matplotlib examples. Rotating 3D wireframe plot. Build fast and responsive sites using our free W3.

If you find this content useful, please consider supporting the work by buying the book! We'll now take an in-depth look at the Matplotlib package for visualization in Python. Matplotlib is a multi-platform data visualization library built on NumPy arrays, and designed to work with the broader SciPy stack. John took this as a cue to set out on his own, and the Matplotlib package was born, with version 0. Matplotlib supports dozens of backends and output types, which means you can count on it to work regardless of which operating system you are using or which output format you wish. This cross-platform, everything-to-everyone approach has been one of the great strengths of Matplotlib. In recent years, however, the interface and style of Matplotlib have begun to show their age.
