Step
Draws a horizontal line from each point to the x value of the following
point, and then a vertical line to that point. You can use Step without
showing points.
Note: The Connect Points, Needle, and Step options are mutually exclusive.

Plots a formula (stored in the Y column) as a smooth curve. To use this
function, store a formula in a column that is a function of a single X
column. Assign the formula to the Y role. For an example, see “Function
Plots” on page 346.
Displays the JMP color palette for assigning colors to connecting lines.
Displays the JMP marker palette for assigning markers to plotted points.
Assigns a color to all points of the selected variable.
Enables the choice of dashed, dotted, or other line styles.
Enables the choice of line widths.
Additional Examples of the Overlay Plot Platform
The following sections show several examples of different overlay plots.
Function Plots
Overlay Plot normally assumes you want a function plot when the Y column contains a formula. However,
formulas that contain random number functions are more frequently used with simulations, where function
plotting is not often wanted. Therefore, the Function Plot option is off by default when a random number
function is present, but on for all other functions.
To See an Example of a Function Plot
1. Open the sample data file Density Compare.jmp.
2. From the Graph menu, select Overlay Plot.
3. Assign gamma1, gamma3, and gamma5 as the Y variables.
4. Assign Xgamma as the X variable.
5. Click OK.
6. Turn of the Show Points option by selecting Y Options > Show Points from the red triangle menu.
