Any metric or non-metric units can be represented by points on the plotted line.
Scatter Graph
A line graph.
A line graph is a type of chart which displays information as a series of points which are joined together. The line joining the points may be straight or in the form of a smoothed curve.A line chart can be used to display information about two or more variables where one variable is plotted along the horizontal axis and the rest are plotted against the vertical axis or axes.

A scatter graph on the data you already have, then place a regression line ( line of best fit) across the points and predict the information based on this line. It obviously isn't accurate and is only a prediction and if there is no correlation in the plotted points and no line of best fit can be placed on there can be no prediction made.

To calculate the potential difference from a graph, you need to determine the vertical distance between two points on the graph that correspond to different potential values. This vertical distance represents the potential difference between those two points. You can measure this distance using the scales on the axes of the graph.
