We have a relative volatile business where weekdays volumes are dramatically higher than weekends and the daytime is dramatically higher than the night time As such when we generate a daily line chart we have a chart that looks like super fast heart beat with lots of peaks and valleys.
We were thinking that it would be great if we could add a 'trend line' to the chart and include the 'equation' for that trend line on the chart. Very similar to how Excel does it.

I think this is a super valuable tool (the equation) that helps quantify the growth (slope) of the line. I'm thinking the comparison of two lines (segment a vs. segment b) with two lines and two equations where equation A shows +1% growth while equation B shows a -2% growth. Proving mathematically that the variance between the two segments is 3%
