Trend Line based on Future Date

[astitzel]

Hi!

I am building a burn up chart for a software development project scheduled to go live on Jan 1, 2022. I am trying to impose a trend line over the data set that calculates slope based on months to 1/1/2022 to see how progress tracks against a rough average velocity, but I can't figure out how to update the line to calculate based off of a date in the future. I've included a screenshot of the current chart below for reference.

Is is possible to restructure the formula for the trend line to instead calculate slope based on months to Jan 2022?

Thank you in advance!

Hi Astitzel,

I am afraid I don't have an answer to your question, I am really intrigued as to how you managed to achieve your trend line on your accumulated values.

I have used this formula:
linest_m(total aggr(if(sum([Hours Worked]),sum([Hours Worked])),Period),Period)*only({1}Period)+linest_b(total aggr(if(sum([Hours Worked]),sum([Hours Worked])),Period),Period)

But when I accumulated the values, the line was no longer lineal!

Can you share how you achieved your trend-line?
