LabPlot highlights unknown syntax in the y=f(x) field. This is useful to control the correctness of the input.
The list of the known functions can be found in corresponding section of this manual.
Switch to the Line tab on the xy-equation-curve properties pane and choose cubic spline (natural) from the Type drop down box.
