Histogram Plot

To plot histograms of results after a Probabilistic Analysis:

  1. Select Histogram Plot from the toolbar or the Statistics menu.

  2. In the Histogram Plot dialog, select the data you would like to plot. The following data can be plotted:

  1. The Number of Bins used to create the histogram, can be customized if desired.

  2. You can also highlight data on the plot, according to user-defined criteria, by selecting the Highlight Data checkbox, and defining your criteria. See below for details.

  3. Select the Plot button to generate the Histogram plot.

  4. Once a plot is generated, there are many different options available, if you right-click the mouse on the plot. See below for details.

Highlight Data

To highlight any subset of data on the histogram:

  1. Select the Highlight Data checkbox in the Histogram Plot dialog.

  2. Select a Random Variable.

  3. Select an operator (< , <= , > , >= , Range).

  4. Enter the numerical value(s) defining the data you would like to see highlighted.

  5. Optional – you can use TWO variables together, combined with either a logical AND or logical OR operator, to create a more complex selection criterion.

  6. When you select the Plot button, data which fits your selection criteria, will be highlighted on the histogram in RED. The highlight criterion will be listed at the top of the histogram.

EXAMPLE: plot a Histogram of an input Random Variable (e.g. a material property), and then define a Highlight Data criterion of Factor of Safety < 1. This will show the distribution of failed analyses, relative to the overall distribution of the material property.

Histogram – Input Data Random Variables

If you are plotting a Histogram of one of your input data Random Variables, then the following information will be displayed on the plot.

NOTE: this information will only be listed if the Input Distribution is displayed on the Histogram. The display can be toggled on or off by selecting the Input Distribution option from the right-click menu.

Histogram – Factor of Safety

If you are plotting a Histogram of Safety Factor, then the following information will be displayed on the plot.

NOTE: this information will only be listed if the Best Fit Distribution is displayed on the Histogram. The display can be toggled on or off by selecting the Best Fit Distribution option from the right-click menu.

Right Click Options

Many different options are available if you right-click on a Histogram. For example:

Experiment with the different options available in the right-click menu.
