Make area start at the bottom of the graph instead of 0 on Area chart?

[bjhorrell]

I would like to make my Area Chart start at the lowest Y value instead of 0 like this.
Is this possible, Thanks in advance.

You can set the lower bound explicitly, e.g. plot.getRangeAxis().setLowerBound(0).

Sorry, I meant the areas starting at the bottom of the graph, instead of revolving around 0 like they do in this picture.

Can you use one of the DatasetUtils to find the desired bound?

[bjhorrell]

I know what the lower bound of my graph is(in this case it's is -10). I just can figure out how to get my areas to start from there instead of 0.

AFAIK, the renderer can only display values in the dataset. Does a third dataset make any sense for this use-case? Cross-posted here.
