PV/QV Curves Results: Legacy Plots

 

Plotting functionality is almost identical for both the PV analysis and QV analysis (exceptions will be noted below). For PV analysis, the Plot tab is accessed from the PV Results tab of the PV Curves dialog. For QV analysis, the Plots tab is accessed from the QV Results tab of the QV Curves dialog. Any of the values selected to be monitored can be plotted using this display.

 

The page is broken into two basic sections: the left and right half. The right half of the display allows selection of the scenarios that should be included on a given plot. The left half allows selection of the quantities that will be charted on the plot.

Selecting Scenarios to Plot

The right half of the display gives a table of all scenarios that were studied. Change the Plot? field to YES to include a scenario in the current plot. The Plot? field is a toggleable field and can be changed from YES to NO and back again by double-clicking on the appropriate entry. Any scenario whose Plot? field is set to YES will be included on the same plot once the Plot button is clicked.

The Always include base case box should be checked if the base case scenario should be included in the plot along with any other scenarios selected. This option is not available for QV results plotting.

Before a plot can be created, the quantities to plot must also be set. The results for each selected element will be plotted for each of the selected scenarios.

Selecting Quantities to Plot

The left half of the display gives the various options for selecting what quantities should be plotted.

The Horizontal axis value drop-down contains any parameters that were monitored. Additionally, for the PV analysis, this drop-down also contains the independent quantities (Nominal Shift, Export, and Import) recorded during the analysis. If the Pre-contingency box is checked, the x values for each plotted scenario will come from the base case instead of the results of a given scenario. The Pre-contingency check box is not available for QV results plotting.

The Vertical axis value type drop-down contains a list of all the types of values that were monitored. The type selected in this drop-down will determine the actual elements that are listed in the Plot values for these elements table. To include an element in the plot, change the Plot? field to YES for that element. The Plot? field is a toggleable field and can be changed from YES to NO and back again by double-clicking on the appropriate entry. Any element whose Plot? field is set to YES will be included in the same plot once the Plot button is clicked.

Before a plot can be created, the scenarios to plot must also be set. The results for each selected element will be plotted for each of the selected scenarios.

Plot Title

Optional field that can be set to add a title to a plot and distinguish one plot from another.

Plot

After selecting the scenarios and values to plot, click this button to actually generate the plot. The plot will appear in its own window. The number of plots that can be created is limited only by computer system memory.

Right-clicking on a plot will expose a local menu with several options. The plot can be saved as a bitmap, Windows metafile, JPEF, or text file by clicking Save and selecting the appropriate file type. Copy will allow the plot to be copied and pasted into other applications. Print will send the plot to a printer that can be configured by selecting the Printer Setup option. Selecting Close will close the plot window.

Clear

Click this button to reset all of the Plot? fields to NO for both the scenarios to plot and the values to plot.
