# Smooth plot

Constant plots draw lines parallel to the x-axis to connect coordinates. The discontinuous edges may be drawn or not, and marks may be placed on left or right ends.

The code is from the PGFPlots 1.10 manual: “4.5.2 Smooth Plots”.

Edit and compile if you like:
\documentclass[border=10pt]{standalone}
\usepackage{pgfplots}
\pgfplotsset{width=7cm,compat=1.8}

\begin{tikzpicture}
\begin{axis}
\end{document}
