Powerchart回归线

我目前正在实施Highcharts的以下趋势线插件:

http://www.highcharts.com/plugin-registry?search=trendline Highcharts regression Date: 2014-05-23 This allows you to add regression lines to any series. Supports: linear, polynomial, logarithmic, exponential and loess. Calculates the r-value. 

有谁知道是否有一种方法来添加Power回归线? 看来,这可能是我在Excel中最常见的(多项式,对数,指数,幂)分组。

我怎么可以添加这个?
