Subject:Question about grid lines unit of measurement.

Hello.

What is the unit of measurement for grid lines? The documentation (http://code.google.com/apis/chart/#grid) states:

chg= <x axis step size>, <y axis step size>, <length of line segment>, <length of blank segment>

What is the "step size"? It does not appear to be pixels. What is this unit of measurement? What is the step size's relationship with the size of the chart?

On a related note, it would be nice if axis labels, range markers, and grid lines could be dealt with in a consistent fashion via the Chart API. In theory, this approach would solve the alignment problems between those entities.

Thank you.
