Trendline decimal places not changing when edited

Question

I have three trendlines on a graph on excel. It has let me change the number of decimal places on the first line using the 'format trendline label'. The other two lines when doing the exact same thing as before it wont let me change the number of decimal places. When I type 2 in and press enter, nothing happens

Answer 1

Hello,

Are those two labels still the original equation labels or were they edited or copied at some point?

When Excel does not change the decimal places, it usually means the label is no longer linked to the trendline format.

Delete each affected trendline label, then turn it back on from Format Trendline by checking Display Equation on chart, and set the decimal places again under Number.

This resets the label and allows the formatting to apply correctly.
