# 3 First steps with Pyxplot

This chapter provides an overview of the commands used to produce plots in Pyxplot. The commands it covers have very similar syntax to gnuplot; if you have used gnuplot in the past, you can find an approximate list of differences between Pyxplot and gnuplot in Appendix B.

The introduction to plotting provided by this chapter will be extended in Chapter 1, which is a complete guide to Pyxplot’s plot styles.
