Any suggestions regarding creating and setting a best fit curve to an Excel Chart (Clustered Column) would be appreciated.

Thank you so much! I appreciate your efforts.

Of course, I performed an Internet Search before I posted here and got much of the same results as your search.

What I can discern is that a program CurveExpert (of which I am unfamiliar) is better suited than Excel to graph a Best Fit Curve over the data points of a chart. Following the exercise suggested at one site for Excel users came to nought- the curve was, obviously, not a best fit.

Unfortunately, I am stuck with Excel. Therefore, is it the consensus that I am, colloquially, "SOL"?

BTW- Thank you also for Jon Peltier's site address.

I'm a little confused by your response. In excel charts, a line (or curve) is nothing more than a series of data points. Creating such a series in your spreadsheet with a best fit curve formula/function/yourmethod then adding this to the chart simply is not that hard.

I noted how to do a combo chart in case you needed to add a line/curve.

What's missing?

The trouble is there is no Best Fit Curve Function in Excel- it simply does not exist.

However, I have already manually overcome the problem.

In any case, thank you for your efforts.

Have you tried adding a trendline from the menu:

That was the first thing I did. The results were obviously not correct.

This regarded experimental data that was portrayed on a column chart.

As I had a deadline, I merely drew in what I knew to be correct.

I do not know what the problem was, I hope it was merely isolated.

I have spoken to others regarding this and it has been pointed out that because Excel does not have a function of ignoring "wild" data points, it is not the best tool for this- however, this was not the case in my situation.

A bit frustrating, but it has passed. Perhaps if it comes up again on this list it may be better studied.
