Use Summary XY Plots to compare plotted results from two or more Scenarios. They are ideal for determining relative performance of design alternatives.
An example of a Summary XY Plot is a Design Study of a water manifold. Several designs are evaluated to determine which produces the most uniform distribution across the legs (before feeding into a discharge pipe). A cutting plane is created through the legs, and the velocity plotted on an XY plot.
The Plot is marked as a Summary Plot, and is then plotted from the Decision Center. The plot shows the velocity distributions from all of the Scenarios in the Design Study, making it very easy to see which is the most uniform.
To display a Summary XY Plot:
- When creating the XY Plot from the Results task, check the Summary box on the XY Plot Dialog. (For more about creating XY Plots...)
- The plot is listed in the XY Plot Data branch of the Decision Center.
- Right click on the XY Plot Data branch, and click Update critical values. If the warning symbol is displayed on a branch, the results in the model do not match the results in the plot. To resolve this, click Update critical values.
- The XY Plot window will open showing the plotted data from the scenarios.
Note: By default, each summary plot shows results from all scenarios. To select specific scenarios for a summary plot, right click on its branch, and pick Select scenarios... Select only the scenarios you wish to compare from the list.
- To change the plotted result quantity, select one from the menu at the top of the dialog.
