Method: Scale#clear_scale

Defined in:
lib/scale.rb

#clear_scale ⇒ Object

You’ll need to call this function only if you’re planning to draw a second chart in the rendered picture. Calling this function will clear the current scaling parameters thus you’ll need to call again the draw_scale function before drawing any new chart.
