from hours I've been looking for a solution to add trendlines to an existing chart built with Chart.js

I think we can only add logarithmic trendline on Chart.js ?

I don't want to draw a trendline from scratch, but add 2 trendlines based on existing data of these 2 lines ; please see this fiddle example :
