Select a comma-separated values file holding the data you wish to plot and/or fit. You may use either commas or tabs as the delimiter between columns. The first row of the CSV file must hold the column labels, which are then used to label the x and y axes. You may surround algebraic variables and Greek letters with dollar signs; e.g., $\theta$ (°) or $L$ (cm) or $T^2$ (s$^2$) or $L_{\rm string}$ (cm). Some characters are special and need to be escaped with a leading backslash, including #. If you run into trouble, try removing non alphanumeric characters from your column labels.

Optional keys — separate pairs with commas
