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 graph, such as on a scatterplot. As you move the mouse pointer, the crosshairs location and coordinates update. Crosshairs are a quick and easy way to explore data on 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 corner 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.

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.
