speed calculation in time graph
It would be very useful to calculate the speed of change in the y axis at every point in the time series. Something like this:
chart.series[0].points[0].y.speed(year)
speed(Year) would calculate the rate of change per year, or month or day of the Yaxis variable,
you could also implement acceleration
chart.series[0].points[0].y.acceleration(year)
