Side-by-Side Plots Control Panel

The control panel in a side-by-side plot shares several options with the control panel in standard plots. In addition, the control panel in the side-by-side plot allows you to select multiple plots to be displayed in a single window.

The appearance of the side-by-side plot control panel with a Weibull++ folio varies depending on whether you choose to vary plot types or distributions. The options available in each case are presented next.

The appearance of the side-by-side plot control panel with an ALTA folio varies depending on whether you choose to vary plot types, distributions or models. The options available in each case are presented next.

Keep Aspect Ratio maintains the ratio of the horizontal size to the vertical size of the plot graphic when you resize the plot sheet.
Use Logarithmic Axes plots the function on a log-log paper.
Confidence Bounds opens the Confidence Bounds Setup window, which allows you to specify the type of confidence bounds you would like to show on your plot.
Life Lines

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.

Contours Setup

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.

In the Scaling area, the X Scaling box shows the minimum and maximum values for the x-axis. You can change these values if the check box beside the value range is not selected. If it is selected, the application will automatically choose appropriate values for the range.

Weibull++ options:

- Vary allows you to select whether to display multiple plot types or multiple distributions. The options available below depend on your selection for this option. (Note that for degradation and warranty folios, the plots are based on the standard data set created from the folio.)
- - If you select to vary plot types, the Plot Types area allows you to select up to nine plot types to be displayed in the side-by-side plot. All will be plotted using the distribution currently used in the data sheet.
  - If you select to vary distributions, the Plot Type area allows you to select one plot type to be displayed in the side-by-side plot. The Distributions area allows you to select up to eleven distributions to be displayed in the side-by-side plot, in the selected plot type. Note that regardless of your choices, the side-by-side plot will display only those distributions that can be successfully calculated and you will receive error messages for any unsuccessful calculations.

ALTA options:

- Vary allows you to select whether to display multiple plot types, multiple distributions or multiple models. The options available below depend on your selection for this option. (Note that for degradation folios, the plots are based on the standard data set created from the folio.)
- - If you select to vary plot types, the Plot Types area allows you to select up to twelve plot types to be displayed in the side-by-side plot. All will be plotted using the distribution and model currently used in the data sheet.
  - If you select to vary distributions, the Plot Type area allows you to select one plot type to be displayed in the side-by-side plot. The Distributions area allows you to select up to three distributions to be displayed in the side-by-side plot, in the selected plot type. Note that regardless of your choices, the side-by-side plot will display only those distributions that can be successfully calculated and you will receive error messages for any unsuccessful calculations. All will be plotted using the model currently used in the data sheet.
  - If you select to vary models, the Plot Type area allows you to select one plot type to be displayed in the side-by-side plot. The Models area allows you to select up to five models (or, in ALTA PRO, nine models) to be displayed in the side-by-side plot, in the selected plot type. Note that regardless of your choices, the side-by-side plot will display only those models that can be successfully calculated and you will receive error messages for any unsuccessful calculations. All will be plotted using the distribution currently used in the data sheet.
- At the bottom of the control panel, the Associated Data Sheet area displays the folio and the data sheet that is associated with the side-by-side plot. Click the folio name to open it

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

Redraw Plot updates the plot to reflect the 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, colors, sizes, etc.

Associate Data Sheet opens the Select Data Sheets window, which allows you to select the data set to be associated with the side-by-side plot.
