We do so below using a different color and line type. We also add a title and axis labels, which is highly recommended in your own work. Also note that we moved the plt.show command to the end so that it shows both plots. newyvals = 1 - 0.5 * xvals**2 # Evaluate quadratic ...

In the next installment, I will be showing you how to make another common type of plot: a histogram. Feel free to leave me comments on what topics I should cover in future posts. Basic Data Plotting With Matplotlib Part 1: Introduction Part 3: Histograms Part 4: Multiple Plots (Coming ...
In this article, I will give you a tour of bar plots in Python using the most well-known libraries- Matplotlib, Seaborn, Plotly, Plotnine, and Pandas. You can eyeball the visuals and choose which library you like best. For each method, I will start with the basics of creating simple ba...

The package requires numpy, scipy, and matplotlib. In addition, some routines use a module called slycot, that is a Python wrapper around some FORTRAN routines. Many parts of python-control will work without slycot, but some functionality is limited or absent, and installation of slycot is reco...
