Tool
The Crop tool enables you to trim the edges of a data set. Use it to remove unwanted data.
The time scale of the trimmed data is shifted so that it will start at
0
=
t
.
If you want the automatic curve fit equation to start at
0
=
t
, apply the crop tool before any type of
curve fitting
After applying the crop tool, the trimmed data set replaces the original set on the graph display and a
new icon is added to the Data Map under cropped data.
