Description

Item

Click the check box(es) and then specify the amplitude or mean values to
manually set the amplitude or mean display range for the X axis.

The Expand Only feature was developed for auto-scaling such that when the
range expanded during auto-scaling, this option prevented the range from
contracting when the command stopped.

Expand Only

Click the check box to allow a range to automatically expand if the data exceeds
the maximum and minimum ranges. The chart does not rescale to a smaller
range.

Specifying the Maximum and Minimum for an axis avoids auto-scaling, however,
also checking Expand Only implies that you want to auto-scale if the data is
outside the specified range.

Toggle between linear scale and log scale for the axis. Select the check box for
logarithmic scale. Leave the box blank for linear scale.

About History Charts

The History Chart plots any variable in relation to the cycle number or block number (that is, the Counter
variable in the Block Information of DAQ). The Y-axis presents data values and the X-axis presents index
values.

History charts are typically one of the first views used for checking test data. For example, strain peak and
strain valley may provide the first signal-strength indicator. History peak and valley curves can also be the
starting points for checking stress and load results.

You can include an image of a History Chart in reports.
