Convert graph to equatio (software)

In summary, the conversation discusses the need for software to convert a graph to an equation and offers suggestions such as using regression analysis with programs like MATLAB or Microsoft Excel's Curve Fitting Toolbox. The conversation also mentions the possibility of using a built-in Excel function for fitted basis functions.

Hi. I'm new to this forum. I would like to ask is there any software that can convert graph to equation. My graph is in xy graph. I need to create a new accurate equation to make data more precisely. Appreciate to anyone who can help.

That's an intractable problem in general. You might try performing regression; any statistics software will do it for you (e.g. MATLAB, R).
 
  • #3
if i have a set of data that able to draw graph, can i apply the data to generate the equation?
 
  • #4
If you have the xy data you can fit a function to it. If you have MATLAB I'd use the Curve Fitting Toolbox, cftool. It offers a nice GUI showing the data set and the fit, and offers several basis functions to choose from.

If you don't have matlab, Microsoft Excel can also do some basic regressions/curve fitting.

Btw, how to call that function out from microsoft excel after ploting the graph?

There's a built-in Excel function that will give you the weights for a fitted basis function; I don't remember what it is.
