scale

scale

In interaction mode scale allows display and graphically read some informations with the means of 2D and 3D scales.
Default is continuous click, see the mouse(s) option to change the mode.

When invoked first time scale(id)type propr(p) ... creates the object type scale type with properties propr(p) ....
Then scale(id)type displays the scale each time it is invoked.
Thoses properries can be changed by scale(id)type propr(p) ... at any time.

Linear scale

scale

       Displays a scale in window (0,0, 100,115), and returns a float between 0.0 and 1.0 when clicking in the box, otherwise returns NIL.
The following Options allow to specify the parameters.

Scale options

scale("eee"): left displays the text "eee".
Notes:
the scale as well as its text, are displayed between x1 and x2, so it is necessary to provide texts the same dimension for scales displayed on several lines.
space and coma are illegal characters in the name of a scale.
