| The above plotting script used the matlab **linestyle** codes '' 'b-' '' and '' 'r-' '' to generate blue and red curves for $\cos x$ and $\sin x$. Matlab's **help** function provides a pretty good description of how line and marker style codes work. | The above plotting script used the matlab **linestyle** codes '' 'b-' '' and '' 'r-' '' to generate blue and red curves for $\cos x$ and $\sin x$.

| + | <code matlab> | ||

| + | ylabel('bar') % add a y label | ||
| + | title('baz') % add a title | ||
| + | legend('first', 'second', 'third') % add a legend with these labels | ||
| + | axis on % turn on axes and ticks (default) | ||
| + | axis off % turn off axes and ticks | ||
| + | axis square % make the plot square | ||
| + | axis equal % scale the x and y axes the same | ||
| + | axis([xmin xmax ymin ymax]) % force these specific bounds on the axes | ||
| + | grid on % turn on grid markers | ||
| + | grid off % turn off grid markers | ||
| + | hold on % hold the current plot; the next plot will be plotted on top of this one | ||
| + | hold off % release the current plot; the next plot will erase this one | ||
| + | clf % clear figure (erase current plot) | ||
| + | figure(2) % open new figure window, numbered 2 | ||
