Sets the use stress value to be plotted (does not affect results of calculations). Double. The Index parameter is an integer that specifies the stress index, where 0 = first stress, 1 = second stress, etc.

## Example

The following example demonstrates how to create a use level probability plot for an ALTA single-stress analysis.

VBA

'Add code to create an ALTA data set and analyze it.
...

'Declare a new WAPlots object.
Dim APlot As New WAPlots

'Add the analyzed data set to the plot.

'Create a use level probability plot for use stress = 200.
'This example assumes that an image control called "Image1" already exists in the active Excel sheet.
Set Image1.Picture = APlot.CreatePlotVB6(WAPlotType_UseLevelProbability)

VB.NET

'Add code to create an ALTA data set and analyze it.
...

'Declare a new WAPlots object.
Dim APlot As New WAPlots

'Add the analyzed data set to the plot.
