Dynamic and action

A process graph has basically two tasks, to show the status of the process to the operator,
and to make it possible for the operator to affect the process.

To show the status of the process you insert dynamics in the graphs. The dynamic can be to

- change the color of an object
- make objects invisible or insensitive
- draw texts
- change the shape of an object
- show analog value
- move, scale or rotate objects
- Sound and commands

To make it possible for the operator to affect the process, you insert actions to objects
in the process graph. By adding action to an object it can also be possible for the operator
to gain more information about the object, from a popup menu or by opening additional graphs
or curves. An action can be

- set values from pushbuttons
- popup menu
- open graphs
- execute commands
- tooltip
- help texts
- input focus
