Analyzing Flatness Measurement Data
Analyzing Flatness Measurement Data
The Analyze Data: FLATNESS screen presents a graphical data display
and a numerical analysis of the measurement data set. You can display
data in two formats: isometric and numeric.
•
To view data in the graphic format, select Isometric Plot from the
option box above the Save Data button in the lower left corner of the
screen.
•
To view data in the numeric format, select Numeric Graph from the
option box above the Add Text button in the lower left corner of the
screen.
As with Analyze Data screens for all other measurements, you can use
this screen to display the measurement dataset. To do this, select Show
Data (or press Alt D).
Understanding the isometric format
The isometric format shows the measurement grid with an isometric plot
of the measurement data as shown in Figure 9-14. The functions available
with this format are explained below.
Rotating the grid and plot
At the bottom of the screen, below the Autoscale checkbox, are four
rotation buttons. Use these to rotate the grid and plot vertically and
horizontally to show different views of the display.
Because rotating the grid and plot can hide line identification letters and
make it difficult to know how the grid and plot are oriented, the three axes
below the AZ Scale box show the current orientation of the grid and plot.
As you rotate the grid and plot, the three axes rotate.
