create customize trendlines

B

beth

How do you create customize trendlines (w/o doing any
additional spreadsheet calculations)? For example, Excel
gives you the option of plotting y=m(lnx)+b. I might like
to plot y=m(logx)+b instead. Does anyone know any easy
way to do this using the trendline option (I've seen
graphing programs where you can edit existing curve fits
or creat new ones.)?

Thanks!
