WAPlotSettings Class

Specifies various plot settings that will be used when a plot is created.

In Weibull++/ALTA, most of these settings are accessible from the Show/Hide Plot Items window and the plot sheet's control panel.

Properties

Confidence Bounds

• ConfBounds_SideSelected (as ConfBoundsSides) Sides of the confidence bounds.
• ConfBounds_TypesSelected (as ConfBoundsTypes) Type of the confidence bounds.
• ConfidenceLevel (as double) Confidence level.
• ContourConfLevel (as double) Confidence level for contour line plot.

Target Reliability

• ShowTargetReliability (as boolean) Whether to show the target reliability line.
• TargetReliability (as double) The value of target reliability.
• ShowTargetTime (as boolean) Whether to show the target time line.
• TargetTime (as double) The value of target time.
• ShowTargetMarker (as boolean) Whether to show the a marker on the intersection of the target reliability and time lines.

Scaling

• AutoscaleX (as boolean) Whether the X-scale is calculated automatically.
• AutoscaleY (as boolean) Whether the Y-scale is calculated automatically.
• Xmax (as double) X-scale end. Only used if AutoscaleX is false.
• Xmin (as double) X-scale start. Only used if AutoscaleX is false.
• Ymax (as double) Y-scale end. Only used if AutoscaleY is false.
• Ymin (as double) Y-scale start. Only used if AutoscaleY is false.

Show/Hide Items

• ShowLeftCensoredPoints (as boolean) Whether to show left censored points on X-axis.
• ShowLinesAroundInterval (as boolean) Whether to show vertical lines around an interval line.
• ShowNumberInGroup (as boolean) Whether to show the number of points in the group for grouped data.
• ShowParameterBar (as boolean) Whether to show the parameter bars as probability plot.
• ShowParameterScales (as boolean) Whether to show the parameter scales as probability plot.
• ShowSuspensionPoints (as boolean) Whether to show suspension points on X-axis.

Axis Labels

• PlotXPrecision (as integer) Precision for labels on X-axis.
• PlotXTolerance (as integer) Tolerance for labels on X-axis.
• PlotYPrecision (as integer) Precision for labels on Y-axis.
• PlotYTolerance (as integer) Tlerance for labels on Y-axis.

Failures/Suspensions Histogram Setting

• HistogramInterval (as double) Interval in histogram plots. Set it to 0 to use the automatically calculated interval.

Plot Legend

• UserCompany (as string) Company name that appears on the plot.
• UserName (as string) User name that appears on the plot.

Other Options

• AdjustMLEPoints (as boolean) Whether to adjust MLE points.
• StraightenGammaLine (as boolean) Whether to streighten the probability line for Gamma and G-Gamma distributions.
