Using crosshairs and flags to display x-, y-, and z-values

What are crosshairs?

Crosshairs are a tool that displays the x- and y-values of any point on a graphs such as a scatterplot. As you move the mouse pointer, the crosshairs location and coordinates update. Crosshairs are a quick and easy way to explore your graph.

Example of crosshairs

In this example, the crosshairs are at x = 1.30570 and y = 5.16129. These coordinates appear in the upper left corder of the graph.

Display crosshairs

  • With the graph active, choose Editor > Crosshairs.

What is a flag?

A flag is at type of graph annotation that displays the precise x-, y-, and z-values for any point on a contour plot that you get with a DOE analysis. Use a flag to determine the response value for a particular combination of factor or component levels. Flags are permanent annotations on the graph; therefore, they are useful for reports and presentations.

Example of a flag

This contour plot shows the effect of injection temperature and injection pressure on the strength of insulation. A flag identifies a particular point on the graph.

Display a flag

  1. Right-click a contour plot from a DOE analysis and choose Plant Flag.
  2. Move the mouse to locate the crosshairs where you want them, then click to plant the flag.
Tip

For added precision, you can plant a flag in conjunction with crosshairs. First, use crosshairs to find the exact coordinates at which you want to plant a flag. Then right-click and choose Plant Flag.
