The interactive command is part of the plots package. It allows you to build plots interactively.

The Plot Builder provides a more flexible interface to building a plot interactively.  For details, see Using the Interactive Plot Builder.

If expr is an algebraic expression or a list, it is taken to be a single expression to be plotted.  If expr is a set of algebraic expressions or lists, these are taken to be separate expressions to be plotted in the same graph.

If present, the variables option provides a complete list of the variables used in plotting.

To generate a plot interactively, use the interactive(expr) command. Follow the instructions in the subsequently displayed dialogs. Maple will generate a plot and display it in the worksheet.

The interactive command can create only one type of plot (for example, plot from an expression, implicitly defined plot, complex plot) at a time. To combine different types of plots, first use the interactive plot builder to plot them separately, then use the plots[display] command to show them together.  See example below.

$\mathrm{with}\left(\mathrm{plots}\right)\:$

$\mathrm{interactive}\left(\sin \left(x\right)+1\right)$

$\mathrm{interactive}\left(\left\{\cos \left(w\right)\,\tan \left(w+z\right)\right\}\right)$

$\mathrm{interactive}\left(\exp \left(x\right)\,\mathrm{variables}=\left[x\,y\right]\right)$

$A≔\mathrm{interactive}\left(\frac{x}{x^2-1}\right)\:$

$B≔\mathrm{interactive}\left(\frac{y}{x^2-1}\right)\:$

$\mathrm{display}\left(A\,B\right)$
