I have seen examples of data providers, but I have not seen one that allows to plot simple functions. For example, how do I plot something like: f(x) = sin(x)

I already figured out how to edit a point's location by setting allow drag's boolean value to true. However, I haven't figured out how to allow drag but only along one axis. For example, I would like to change the Y-value only when I drag a point. Is this possible? If so, how?
