Parametric Extrusion 1D and Parametric Extrusion 2D
Use a Parametric Extrusion 1D () or Parametric Extrusion 2D () dataset to extend another dataset by using a parameter, such as time, as a dimension. Select these from the More Datasets and More 2D Datasets submenus.
Settings
From the Level transformation list, select None (the default) to use no transformation of the extrusion level, or select Expression to enter an expression in the Transformation expression field. The default expression is level, which is a predefined variable for the extrusion level (that is, no transformation). You can instead use an expression that is a function of level, such as log10(level) for a logarithmic transformation to create a directivity plot, for example.
Select the Level scale factor check box to edit the field. The default factor value is 1. The level scale factor applies to the transformed levels. The Separate levels check box is selected by default for plotting data for each equidistant point in time, for example.
