Issue Details
It should be possible to plot mathematical funtions in 2D charts.
Expected Behavior
For 3D charts, it is already possible to have mathematical functions in the chart options which will then be plotted. I think it would be nice to have that possibility for 2D charts as well. For example, I might have the formula for a polynomial regression over a timeseries and would like to plot it. At the moment, I would have to generate an array of points for that regression and create a new series from that array. It would be helpful to have a callback instead, which calculates the value from a given timestamp.
If this is already possible, please tell me how to do it.
Current Behavior

dygraphs can do it, see here: http://dygraphs.com/gallery/#g/plotter
