[Solved] Charts: Surface charts

Hi

I know how to plot a surface chart. Is there anyway I can fit a equation to the data? Any ideas are highly appreciated.

Thanks

Hi lambuhere1,

You obviously know that Add Trend Line is not an option.

Maybe you could supply more information about what sort of equation you wanted to use and why? An example perhaps.

Cheers
Andy

Hi Andy

Great to hear from you. I had a plot of 3D Surface plot with the necessary data. It shows in 3D format according to the data supplied. Now I need to fit a equation for this surface generated. I know its a tough job. But is there any way we can fit a surface equation for this plot.

I hope I am clear on this. If not, do let me know

Thanks

Hi lambuhere1,

Maybe you could post a workbook with the chart & data you have. (email direct if confidentiallity required)

I will have a look, but don't get to hopeful

Cheers

Hi lambuhere1,

I haven't discovered a solution.
Although this might be worth a look.

You will have to re-arrange your data and add the x and y values.

Also, as your example looks a lot like Tushar's example :wink1: I suggest it might be worthwhile sending him an email. He may know of an approach or even an addin.

Cheers
