Graph menu commands
The Graph menu provides commands that control which graph is available for inspection using the Interactive-Graph view. It also provides a command for resetting the graphs in the Four-Graph view to their default values, and a command for copying data to the Windows clipboard.
|Spatial Graphs||This selection provides a menu of choices for interactive graphs that display spatial information (functions of position). If the information you seek is not included in this list, many more functions are available for a Defined Graph.|
|Temporal Graphs||This selection provides a menu of choices for interactive graphs that display temporal information (functions of time). Some functions not included in this list can be accessed for a Defined Graph.|
|Defined Graph||This selection opens a dialog box which allows you to specify x and y functions for any graph, selected from 75 available functions. These functions provide a much more detailed look at the operation of the device than is available from the predefined graphs.|
|Auxiliary Graph||This command opens a dialog box for selecting a spatial function and a position within the device. Once this information has been entered, any subsequent transient solutions will store the value of that function at that position as a function of time. The data can then be viewed as using the Auxiliary selection from the Temporal Graph menu.|
|Experimental||This command opens a dialog box for selecting data from an external file. The data can be viewed on a user-defined graph with “Experimental Data” as one of the data types. The experimental data file should be a tab-delimited text file. No unit conversion is performed on this data – it’s your responsibility to ensure that the data is sensible.|
|Default Graphs||This command is only active in Four-Graph view, in which case it resets the four graphs to the default selections. When graphs are chosen for interactive examination, they are added to the four-graph view, displacing the default graphs that were there initially. This is done to make it easy to return to those graphs, by double-clicking on them in the Four-Graph view. However, if your attention shifts to a new issue, you will likely want to restore the default graphs, which are chosen to provide a balanced overview of the device's operation.|
|Previous History Graph, Next History Graph||Whenever a simulation is completed, the current interactive graph is saved (to a maximum of 100 graphs). You can view these ‘history’ graphs using the Graph menu or the Page Up/Page Down keys.
By flipping through these graphs, you can visually compare simulation results. This feature is especially useful for batch runs.
|Retain zoom for history graphs||If this is OFF, the previous (history) graphs will be auto-scaled, so that they are fully visible. Unfortunately, this means that the axes can change, making it hard to compare different results. If Retain Zoom is ON, the axes will not change. You can zoom into a part of the curve, then see how that portion differs from other simulation results. You can zoom out to see the full graph.|
|Reset history graphs||Removes all the accumulated history graphs, allowing you to start afresh.|
|Copy Data||This command for copying data to the Windows clipboard for export to other programs is enabled in two situations. First, it is enabled for the Interactive-Graph view, in which case this command copies the data that is currently displayed on the graph. Second, it is enabled in Parameter view if Batch Mode is being used, in which case this command copies the data from the batch table to the clipboard.|
