How to change the start point of trend line?

[qzqzjcjp]

I made a chart with trend lines. The trend lines both start from the middle of green bar and yellow bar. I want to change them to start from the middle of blue bar and green bar.*How to do this? Thank you.
I have attached the data.

Hello,

By default a trendline starts in the center of the first data set, but you can tweak it a bit.

Format the trendlines and enter a number in the Backwards forecast setting. A value of 0.2 should do the trick.
