Producing a 1D Scalar Plot

Procedures:

• It is first necessary to input a data FILE. This activates the Window/Slicer Widget (depicted below).
• Then, select a FIELD.
• At the Window/Slicer Widget, "fix" or "average" all coordinates except one. If this variable is a vertical coordinate such as height, it will become the ordinate in your 1D plot. If the variable is a horizontal coordinate such as X or Y, it will become the abscissa in your 1D plot. Adjust the range of the free variable using the appropriate slider bar (see also WINDOW).

NOTE: The number of variables that you allow to vary determines the number of dimensions contained in the plot. For example, if two coordinates are "free", then IVE will create a two-dimensional plot. If you "fix" or "average" all coordinates, then a Value Info Window is activated, displaying the value of the field at the fixed point you have specified.

• Once you have selected the coordinate for the 1D plot, the IVE Main Window is automatically changed to a one-dimensional mode. Make sure that "Line Plot" is displayed, unless you wish to plot a Skew T, Log P diagram of a temperature profile (see Plotting a Temperature Profile on a Skew T, Log P Diagram).

• An 1D Properties Window (pictured below) will also appear automatically when you select the coordinate for the 1D plot. The properties window allows you to specify axis ranges, scales, and tic intervals. Both linear and logarithmic axis scales are available in IVE and can be selected by clicking on the appropriate diamond-shaped button. The range and domain as well as Major and minor axis tic intervals can be specified by clicking on the apropriate boxes and inputting the desired values. If "d" or "default" is entered in any box, IVE automatically determines a value for your plot.

• Finally, when all parameters have been set, click on "New Plot" in the IVE Main Window to display the plot, or "Overlay Plot" to overlay an existing plot (see PLOT and OVERLAY PLOT).
