Method: Rubyvis::Mark#scale

Defined in:
lib/rubyvis/mark.rb

#scale ⇒ Object

The current scale factor, based on any enclosing transforms. The current scale can be used to create scale-independent graphics. For example, to define a dot that has a radius of 10 irrespective of any zooming, say:

<pre>dot.shape_radius(lambda { 10 / self.scale})</pre>

Note that the stroke width and font size are defined irrespective of scale (i.e., in screen space) already. Also note that when a transform is applied to a panel, the scale affects only the child marks, not the panel itself.
