Parameters
- id: the object's ID, used by UISets. Required
- position: the object's position. Use the pixels or rows and columns coordinates format
- size: the chart's area's width and height
- attributes: list of UI attribute ids and values defining the chart's aspect and data. Setting this parameter is the same as setting each UI attribute with a UISet
Chart types
The type attributes defines the way the values are displayed.

Syntax
(chart!<id> <address>; <position>; <width>; <height>; <attributes>)
E.g.
(chart!chart1 x3y187; 312; 180; (type=line; values=0,10,24,12,7,35,42,1,23,4))
