Can LaTeX create graphics with mathematical curves?

Question

I am trying to see how good LaTeX is.

Can someone show me whether graphics like this.

Thank you due to copyright complains removed the figure.

As other people mentioned, you could use tikz, it has a great manual.

You could also draw the picture with Matlab and use matlab2tikz to generate latex code. Below is an example that draws three sub-figures and a legend.

\documentclass[a4paper,11pt]{article}

\usepackage[margin=1.5cm]{geometry}

\usepackage{pgfplots}
%\usepackage{tikz}
%\usetikzlibrary{plotmarks}
