From version 1.5 and up, matplotlib offers a range of pre-configured plotting styles. Setting the style can be used to easily give plots the general look that you want. Setting the style is as easy as calling matplotlib.style.use(my_plot_style) before creating your plot. For example you could write matplotlib.style.use('ggplot') for ggplot ...

This tutorial explains matplotlib�s way of making plots in simplified parts so you gain the knowledge and a clear understanding of how to build and...Matplotlib is a great tool to visualise two-dimensional geometric data (and 3D data to some extent). You can also use it to dynamically visualise the convergence of an iterative solver. Surprisingly, you don’t need any fancy functionality to accomplish this, such as, for example, the FuncAnimation object of the animation package.
As such, the rendering of mixed 3d scenes is impossible in the general case because either the surface artist or the scatter artist has to be drawn before the other. You might want to look at glumpy, which is an open GL project that borrows heavily from matplotlib. It does true 3d rendering, and may be more suitable for your needs. …
Using Matplotlib, you can draw lots of cool graphs as per your data like Bar Chart, Scatter Plot, Histograms, Contour Plots, Box Plot, Pie Chart, etc. import matplotlib.pyplot as plt plt.scatter(x,y) plt.show() Let's continue with the gdp_cap versus life_exp plot, the GDP and life expectancy data for different countries in 2007.
Plotting a 3D Scatter Plot in Seaborn Seaborn doesn't come with any built-in 3D functionality, unfortunately. It's an extension of Matplotlib and relies on it for the heavy lifting in 3D. Though, we can style the 3D Matplotlib plot, using Seaborn.
