Graph negatives values seems impossible about rickshaw HOT 7 CLOSED

Sample graph :

var data = [ { x: 0, y: -40 }, { x: 1, y: 3 }, { x: 2, y: -17 }, { x: 3, y: -42 } ];

var graph = new Rickshaw.Graph( {
element: document.querySelector("#chart"),
width: 580,
height: 250,
series: [ {
color: 'steelblue',
data: data
} ]
} );

graph.render();

The minimum graph value is hardcoded to 0 in all of the renders, for instance: https://github.com/shutterstock/rickshaw/blob/master/src/js/Rickshaw.Graph.Renderer.Line.js#L35

I've fixed it in my fork here: https://github.com/andrew/rickshaw/commit/7dc125e79326d94bdbf44d5337c78050757dd9c5

Any chance this change can be merged in the main project? We have a few data sets with negative values, would be very nice to have ...

I'll send a pull request

Thank you, much appreciated.

I've implemented a fix, where you can set a min-property on your graph. Being any number you wish, 'auto' (picks the lowest value in your current dataset), or just not define it (will fall back to the current default; 0).

Pull request sent, should apply to current HEAD.

This is merged in with 6a75eae

If you specify min: 'auto', in the Rickshaw.Graph constructor, you should be able to graph negative values.
