You can type in your data by hand in the boxes below, or you can choose a CSV file and choose "populate data" to fill in the boxes automatically.

The CSV file has a very specific format. The first line should be: xlabel,<blank> , ylabel, <blank>. All Subsequent lines should be x, x uncertainty, y, y uncertainty.

You can download an example .csv file after clicking 'load data' below.

This graphing program will not work without x and y uncertainty estimates for each data point.

Enter your x label

Enter your x values (comma delimited)

Enter your x uncertainties (comma delimited)

Enter your y label

Enter your y values (comma delimited)

Enter your y uncertainties (comma delimited)

Once the all the data points and uncertainty estimates are entered into the above boxes correctly, click "Load Data" and a data table will appear to the right. If the data table looks correct you can move on to manual data fitting or auto data fitting.

y minimum value

y maximum value

How many fit parameters do you need?

Type in the fit function using R-Language syntax. Use 'x' as you independant variable and 'A', 'B', 'C', and 'D' as unknown constants that will be fit to your data. IT IS CRITICAL THAT THE NUMBER OF FIT PARAMETERS (ABOVE) EXACTLY MATCH THE NUMBER OF CONSTANT A, B, C, AND D THAT YOU USE IN YOUR FUNCTION. DOING OTHERWISE WILL CRASH THE PROGRAM.

Enter your fit fuction.

starting value of A

starting value of B

starting value of C

starting value of D

Choose "auto fit" if you want the computer to try to find the best values for the fit paramenters. Use "Manual Fit" to use the values you entered for the curve fit.
