y-stretch-to-zero attribute

Used By:linegraph
See:x-stretch-to-zero xaxis-at-zero y

Whether to always include the value "zero" on the y axis.

As an example, if your Line graph plots values from y=10 to y=30, the range of values on the y axis will go from 10 to 30 if this option is false, or from 0 to 30 if it's true.
