You can use the Query toolset to obtain information about curves in an X–Y plot. As you position the cursor over an X–Y curve in the current viewport, ABAQUS/CAE highlights the nearest curve point and displays the curve legend text, the point's sequence identification, and the X- and Y-coordinates of the point in the Probe Values dialog box. You can choose to display only the curve points that comprise an X–Y data object or to interpolate to display arbitrary points along the curve.
To help locate X– and Y–data points you may want to produce an X–Y plot with curve symbols visible before using the Query toolset. For more information, see “Customizing the symbols used on an X–Y curve,” Section 29.6.5.
To probe X–Y plots:
Locate the Probe Values dialog box.
From the main menu bar, select Tools
Query or click the 
tool in the toolbar. Select Probe values in the dialog box that appears; then click Apply. The Probe Values dialog box appears.
At the top of the dialog box, toggle Interpolate between points to enable or disable the display of probe values for arbitrary points along the curve.
When you enable interpolation, ABAQUS/CAE displays the sequence identification of arbitrary points by listing the bracketing X–Y data object points in parentheses.
In the Probe Values field, click table rows to toggle probe display.
Move the cursor to probe the X–Y plot in the current viewport.
As you position the cursor over a curve point, ABAQUS/CAE displays the values of the items you have requested in the Probe Values table in the Probe Values dialog box.
To select and accumulate values of interest, and to allow subsequent writing of these values to a file, click mouse button 1 while positioning the cursor over a curve point.
ABAQUS/CAE stores the legend text, sequence identification, and X- and Y-coordinates of the current point into the Selected Probe Values table.
To delete data from the Selected Probe Values table or to clear or sort the table, click mouse button 3. For more information, see “Entering tabular data,” Section 3.2.7.
To save the data you have selected, click Write to File. For more information, see Chapter 35, “Generating tabular data reports.”
To exit probe mode, do one of the following:
Click the cancel 
button in the prompt area.
Click Cancel in the Probe Values dialog box.
Click mouse button 2.
Produce a plot in some other (e.g. undeformed, deformed) mode.
