    Fit Graph
In summary, the conversation discusses the need for a program that can perform various tasks related to graphing and creating best fit equations. These tasks include creating a spreadsheet based on samples taken from a freedrawn graph, creating a best fit equation for a freedrawn graph, and finding the best fit equation for given x-y arrays. The graph in question is non-linear with two curves and a linear line connecting them. The program CurveExpert was mentioned as a potential solution, although it may not have all the desired features.

I am looking for any program which would allow me to do one of the following:

1) Freedraw a graph and have a set number of samples taken from that graph and create a spreadsheet (x-y)

2) Freedraw a graph and have a best fit equation made

3) Given x-y arrays, create a best fit equation for them


IMPORTANT to know that the graph is non-linear, and consists of two curves and a linear line connecting the curves.

A program called CurveExpert formerly was available (downloadable). It was not fancy enough to do everything you listed, but at least you could select the points you want to include and enter them manually, and then use the commands and menus to find the best fit that you want.
 

Related to Freedraw graph to best fit equation

What is the purpose of freedraw graph to best fit equation?

The purpose of freedraw graph to best fit equation is to visually represent a set of data points and determine the best equation that fits those points. This can help in making predictions and understanding the relationship between the variables in the data.

How do you create a freedraw graph to best fit equation?

To create a freedraw graph to best fit equation, you will need to plot the data points on a graph and then use a drawing tool to draw a line or curve that best fits the points. This can be done manually or with the help of software or online tools.

What are the steps involved in using freedraw graph to best fit equation?

The first step is to gather and organize the data points that you want to plot on the graph. Then, you will need to choose a suitable scale for the axes and plot the points accordingly. Next, use a drawing tool to create a line or curve that best fits the data points. Finally, analyze the equation of the line or curve to understand the relationship between the variables.

Can freedraw graph to best fit equation be used for any type of data?

Yes, freedraw graph to best fit equation can be used for any type of data as long as there is a relationship between the variables. This method is commonly used in various fields such as statistics, economics, and science to analyze and interpret data.

What are the limitations of using freedraw graph to best fit equation?

One limitation is that the accuracy of the equation depends on the accuracy of the data points and the interpretation of the person creating the graph. Additionally, this method may not work well for complex data sets with multiple variables or non-linear relationships.
