How to draw/find a Trendline in PowerBI August 2017 Preview App?

[Rck7]

Hi Friends,

I am trying to figure out a way to draw  a trendline for the number of Tokens used/month on my Clustered Column chart. I am not able to find the Trendline option on my Analytics pane. How would I be able to draw it for my chart?

Any help would be very much appreciated. 
Thank you.

@Rck7,

A trend line is only available with a continuous X axis. You may take a look at line chart and vote this idea up.
