Setting Postprocessing Preferences

You can control postprocessing options for contour or surface graphs on the Runtime Gateway.

  1. From the Design Gateway Edit menu, click Preferences.

  2. Expand Gateway, click Postprocessing, and set the following options as desired:

    Option Description
    Clip Z-Axis Values to Actual Data Range Remove values that are outside the data range. When creating a three-dimensional surface from a set of data points, some Z-axis values may extend past the actual data range. If you select this option, Isight removes the values that are outside the data range from the graph.

    Note: You can alter this value when creating a contour or surface graph. For more information, see Creating Graphs for Components.
    Data Fitting Method Select the technique used to create a three-dimensional surface from a set of data points:
    • Simple Fit. Generate a surface that passes through all of the actual data points. Simple Fit is the fastest and least complex technique. However, it can be inaccurate in regions where no data exist, particularly on the edges of the regions being viewed. By default, this option is selected.
    • RSM Approximation. Automatically create an Response Surface Model (RSM) approximation with quadratic polynomial order for the selected data points. Isight creates a surface graph of this quadratic approximation. You can use this option to smooth out the noise in the data. If the range of inputs is large and/or the shape of the underlying data is very complicated, significant differences can result between the underlying data points and the displayed surface graph. This option is more complex and time-consuming than the Simple Fit method.
    • RBF Approximation. Automatically create a Radial Basis Function (RBF) approximation for the selected data points. Isight creates a surface graph of this RBF approximation. You can use this option to smooth out the noise in the data. RBF approximation is capable of following complicated data more closely than the RSM approximation, which reduces the potential differences between the underlying data points and the displayed surface graph. This option is the most complex and time-consuming and can slow down the responsiveness of the Runtime Gateway while the graph is created.

      Note: You can alter this value when creating a contour or surface graph (see About Data Fitting Methods).
