Use this alternative if you want to display lines based on X and Y coordinates that already exist in two columns of your analysis. For example, coordinate values could be calculated from the input data using a statistical calculation in a data function and the output result could be presented as coordinate values for a curve.
When the line is drawn from column values it is also possible to show predictive values, if these are available:
Note that lines cannot be drawn when categorical scales are used on the axes.
