5.3.0 Charts and Tables (Views)
5.3.1.0 Array-Variable Chart
The Array-Variable chart shows data that is collected and calculated during each test cycle and stored in
arrays. This chart is used in several ways:
• As a runtime display activity
• As an analysis tool in the Fracture Analyzer application
• As an image in reports in the Reporter Add-In for Excel
An Array-Variable chart plots the entire variable array. The data is not cyclic or time-based. The Y axis of the
chart must be an array variable. The X axis can be an array variable or the index of the Y axis array. You can
add multiple traces to the Y axis, and you can add multiple Y axes. When the chart has multiple traces, a
legend on the chart identifies the individual traces.
You can create new numeric variables when you define additional traces. Click the variable
list item to display the New Numeric Variable window.
You can include Array-Variable charts in reports.
5.3.2.0 History Chart
Overview
The History chart shows minimum-maximum or peak-valley cycle data in relation to time or an index, such
as a data group, data point, or cycle number. 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.
Analysis
History charts are also available in the Fatigue Analyzer and Fracture Analyzer applications.
If more than one type of group is available, select a value from the drop-down list. The default value is Cycle.
Other variables listed in this box are variables specified in the Save Variables box of the Map Variables
window.
If an invalid cycle is selected for the chart, a warning icon appears with the error message, “Invalid cycle
values are not plotted.”
5.3.3.0 Hysteresis Chart
The Hysteresis chart shows the cyclic or group data produced during a test cycle.
