Regression Line - Hover/Label Text



I wonder how %_slope is being calculated by Domo within the Hover or Label Text fields in the Regression Line Chart Properties.

When I tried to calculate the numbers within the last 3 months, the result is consistent with Domo's calculation of slope (%_slope).

However, I couldn't figure out why Domo's calculation of slope is inconsistent to mine when the numbers calculated is 4 months and up. Is there something more to the equation that I might have failed to consider?

Here's the regression line properties applied:

I ticked the 'Include Last Data Point' because I am using a filter to exclude the 'on-going' month anyway. Therefore, this should not be an issue esp that this property is applied to both cases above but their results are different.

    That is very strange. It looks like it's maybe including the difference in the number somehow. I tried a few different calculations to see if I could do some hinky math to ascertain what is happening, and no dice!

    I recommend opening a support ticket.

    Hi @DataMaven, Thank you for looking into this. I've done the same thing and I didn't come up with anything that would result to a slope of -1.3. I better file a support ticket for this now. Thank you.
