Target length vs. depth graph
For a target length variable, the Target Length vs. Depth graph shows a scatter plot of the estimated target length against depth.
Warning: Depth is plotted using Target_on_axis_depth not Target_true_depth.
To display a Target length vs. Depth graph for a selection:
-
Make a selection.
-
On the Shortcut (right-click) menu, point to Graph Selection, and then click Length vs. Depth.
To display a Target Length vs. Depth graph for a region:
-
Select an existing region or define a new region.
Note: If you wish to graph a bad data region, you must clear the Exclude bad regions option on the Analysis page of the Variable Properties dialog box.
-
On the Shortcut (right-click) menu, point to Graph Region and then click Length vs. Depth.
