I am sourcing the legend text from the 1st row in the worksheet. It is a serial dilution, so it drops away fast through orders of magnitude. On the worksheet it is represented as 0.00000034731283 but I would love the legend to say "3.47 x 10-7" for example. The legend has decided to change to scientific notation once it goes below x 10-5 but I'd just like it all to be one way or the other.
