Chapter 15: Creating Graphs GUI: Utility Menu> PlotCtrls> Style> Graphs Labeling the curves. For POST26 plotted-variable graphs, the labels applied to your curves are established when you choose one of the following: Command(s): NSOL, ESOL GUI: Main Menu> TimeHist Postpro> Define Variables Main Menu> TimeHist Postpro> Elec&Mag> Circuit> Define Variables For all other types of graphs, including array parameter (*VPLOT) curves, the default label will be the item or parameter name specified in the display action command. For these curves, you can use the /GCOLUMN command (Utility Menu> PlotCtrls> Style> Graphs) to change the curve labels. The /GCOLUMN command allows any text or character string to be used as a curve label. Adding user-defined graphics and text. You can add extra graphics and text to your displays using the annotation functions by choosing Utility Menu> PlotCtrls> Annotation. See Annotation (p. 263) of this manual for additional details. 15.2.3. Defining X and Y Variables and Their Ranges The following subsections detail how to define X and Y variables and their ranges. 15.2.3.1. Defining the X Variable In POST26 plotted-variable graphs, by default, the program uses TIME (or, for harmonic response analyses, frequency) for the X variable. TIME does not always have to represent chronological time. In setting up a time-independent analysis, you can arbitrarily define TIME to be equal to the value of some other item of interest (such as input pressure). To define a different parameter (other than TIME) against which the Y variable is to be displayed, use the NSOL, ESOL, and XVAR commands or their GUI equivalents. 15.2.3.2. Defining the Part of the Complex Variable to Be Displayed When plotting harmonic-response results in POST26, you need to decide what part of the complex variable (amplitude, phase angle, real part, or imaginary part) to display in your graph. Make your choice using the PLCPLX command (Main Menu> TimeHist Postpro> Settings> Graph). 15.2.3.3. Defining the Y Variable The various graphics "action" commands define the Y variable. Sometimes, these commands refer to labels that have been defined in other commands. For instance, PLPATH uses labels defined in the PDEF, PVECT, PCALC, PDOT, and PCROSS commands. PLVAR also uses labels defined in the NSOL and ESOL commands. PLSECT, FSPLOT, and *VPLOT, on the other hand, identify the Y variable directly. (For the GUI equivalents to these commands, see their descriptions in the Command Reference.) 15.2.3.4. Setting the X Range The /XRANGE command (Utility Menu> PlotCtrls> Style> Graph) enables you to graph only a portion of the full range of X-variable data. This command allows you to "zoom" in or out on a particular segment of your curve. 260 Release 13.0 - © SAS IP, Inc.

15.2.3.5. Defining the TIME (or, For Harmonic Response Analyses, Frequency) Range The PLTIME command (Main Menu> TimeHist Postpro> Settings> Graph) enables you to establish a range of TIME for graph displays. ANSYS always displays TIME in the Z-axis direction. If XVAR = 1, TIME is also displayed in the X-axis direction. PLTIME or its equivalent then also sets the abscissa scale range. (A range established by /XRANGE takes precedence over one defined by PLTIME.) 15.2.3.6. Setting the Y Range 15.2.3. Defining X and Y Variables and Their Ranges By default, your graph will contain the full range of available Y-variable data. Use the /YRANGE command (Utility Menu> PlotCtrls> Style> Graph) to define a smaller or larger range. The NUM argument allows you to selectively define different ranges for different curves (providing you have established separate Y-axis scales). Release 13.0 - © SAS IP, Inc.
