Special Tools
Crop Tool
The Crop tool enables you to trim the edges of a data set. Use it to remove
unwanted data or to apply manual curve fitting to a desired range of data
points.
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.
To trim all data up to a point
1. Position a cursor (see page 74) on the data point
2. Click on the
Graph
menu, then click
Crop
To trim all data outside a selected range
1. Use the cursors to select the range you want to keep
2. Click on the
Graph
menu, then click
Crop
