# B.5 Plotting parametric functions

The syntax used for plotting parametric functions differs between gnuplot and Pyxplot. Whereas parametric plotting is enabled in gnuplot using the `set parametric` command, in Pyxplot it is enabled on a per-dataset basis by placing the keyword `parametric` before the algebraic expression to be plotted:

`gnuplot> set parametric`
`gnuplot> set trange [0:2*pi]`
`gnuplot> plot sin(t),cos(t)`
`pyxplot> set trange [0:2*pi]`
`pyxplot> plot parametric sin(t):cos(t)`

This makes it straightforward to plot parametric functions alongside non-parametric functions. For more information, see Section 1.6.
