Combining the data objects
In this section you will create a stress versus strain data object by combining the stress versus time and
strain versus time data object
.
To combine the data objects
In the Results Tree, double-click the XYData container
From the Create XY Data dialog box that appears, select Operate on XY data and click Continue
An
Operate on XY Data dialog box appears. The dialog box contains the following lists•
The XY Data field on the left contains a list of existing X–Y data objects•
The Operators field on the right contains a list of all the possible operations you can perform
on the data objects
From the Operators field, click combine(X,X). combine() appears in the expression text field at the top of the dialog box.
In the XY Data field, drag the cursor across both the Strain and the Stress data objects to select
both and click
Add to Expression near the bottom of the dialog box.
The expression
combine("Strain","Stress") appears in the expression text field. In this expression "Strain" will determine the X-values and "Stress" will determine the Y-values in
the combined plot.
From the buttons along the bottom of the Operate on XY Data dialog box, click Save As.
From the Save XY Data As dialog box that appears, enter the name Stress-Strain and click OK
The new data object
Stress-Strain appears in the XYData container.
Cancel the Operate on XY Data dialog box.
