7.3.7 Changing the curve labels
Each measurement curve displayed in WinCHAP has a corresponding label that
is used to identify the curve. By factory default, the curve label automatically
used for each curve contains its source type, source amplitude, and the scaling
used for the measurement. If desired, however, you can change this curve label
to be whatever you want it to be. You can create custom labels that will be used
by default for all tests, and you can change the labels just for a specific test.
To create
custom labels for multiple curves:
1. Open the View menu and select Custom Curve Labels. This will open the
Set Curve Labels window.
2. Select Custom Labels at the bottom of the window under Curve Labels.
3. Enter the custom labels you want to use for Curves 1-12.
4. Click Apply Changes. This will apply the custom labels to all the curves
for this particular test.
5. Open the Tools menu and select Save Custom Labels as Default if you
want to use these custom labels for all future tests. Otherwise these
changes will only be used for the open test.
To create a custom label for an individual curve:
1. Right click on the curve label you want to change.
2. Select Change Label. This will open the Change Curve Label window.
3. Enter the new label into the provided box.
4. Click OK. This will close the window and change the label of the
response curve.
