ALTA Degradation Plot Sheet

After you analyze the degradation data in the ALTA degradation analysis folio, you can click create plots of your results by choosing Degradation > Analysis > Plot or by clicking the Plot icon on the Main page of the control panel.

The Plot Type area on the plot sheet of the control panel allows you to select the type of plot you wish to view and the units of measurement you want the x-axis of the plot to be displayed in. The plot types available include all of the ALTA plots. These are generated by analyzing the extrapolated failure times at the accelerated stress levels.

In addition to the ALTA plots, you can view the following plots, which pertain specifically to the extrapolation of failure times from the degradation measurements.

Degradation vs. Time (Linear) plots the degradation of each test unit over time, using a linear scale for time and degradation. A thick horizontal line marks the critical degradation level (i.e., the level at which a unit is considered failed) that was specified on the Main page of the control panel. You can use this plot to visualize how failure times were extrapolated for each unit.
Degradation vs. Time (Log) plots the same information as the Degradation vs. Time (Linear) plot, but using logarithmic axes for time and degradation.

The Unit IDs area of the control panel will display the unit IDs you entered in the data sheet of the folio. To remove a test unit from the plot, clear the associated check box.
