Make Plot

Description

Initialize a graph for plotting data obtained from a controller.

(make-plot)

Syntax and Default Values

The (make-plot) function can be created using the following Lisp syntax:

(make-plot)

Parameters

This command initializes a graph, and returns a reference to it. It has no additional parameters.

Discussion

You should use (make-plot) before calling any of the other plotting functions, since they need the reference to the graph it creates. Here is a simple example of how to use this plotting feature (the resulting graph is shown, above):

(setq my-env (make-controller 'envelope 1 '((0 0) (1 1) (2 0))))
(setq graph (make-plot))
(plot-value graph "my-envelope" my-env)
(run 2)
(plot graph "My Plotted Controller Data")

Naturally, the (new) command deletes all plots when it clears the workspace.

Options

Retro-Compatibility

In very old versions of Modalys, the plot feature worked slightly differently. Older scripts may need to be updated to the new syntax.
