Overlay Plot Control Panel

The control panel in the overlay plot is similar to the control panel in standard plots. However, the control panel in the overlay plot allows you to select multiple data sets to be displayed in a single plot.

The control panel tools include the following options:

Opens the Specify Life Lines window, which allows you to enter up to 10 unreliability values for each additional life line you would like to see plotted on life vs. stress plots.

Opens the Contours Setup window, which allows you to select the contour lines to be shown, the confidence levels represented by the lines and resolution. This option is available only for Contour plots. If an error in calculating the selected contour lines is encountered, this button will turn red. Use the Contours Setup window to adjust the settings.

This option is available only if the data sheet uses the MLE analysis method. If selected, it adjusts the y-axis plotting positions so that the data points are plotted directly on the MLE line (i.e., at the position where the failure time intersects the MLE line). The solution of the MLE line is obtained from the likelihood function and not from the plotting positions of the points; therefore, this plot setting does not affect the parameter estimates.

Opens the Use Stress Level window, which allows you to enter a use stress value for the selected stress type.

The folio tools are arranged on the left side of the control panel:

  Redraw Plot updates the plot to reflect any changes that have been made.

  Plot Setup opens the Plot Setup window, which allows you to customize most aspects of the plot including the titles, line styles and point styles.

  Edit Plot with RS Draw launches ReliaSoft Draw, which allows you to annotate your plot and view your plot in greater detail.

  Export Plot Graphics opens the Save As window, which allows you to save the current plot graphic in one of the following formats: *.jpg, *.gif, *.png or *.wmf.
