Parallel Coordinate Post Processing

Visualize data trends.

Visualize Data Trends

Visualize all run data across multiple channels on a single plot in the Parallel Coordinate post processing tab.

A parallel coordinate plot is also known as a snake plot.

  1. From the Post Processing step, click the Parallel Coordinates tab.
  2. From the Channel selector, select the channel(s) to plot.
    Each channel is represented by a vertical line, or axis. By default, the min and max range for each selected channel is displayed at the top and bottom of an axis.

    Run data is represented as a horizontal, colored line passing through the axes.

  3. Analyze run data.
    Option Description
    Display evaluation index and run data Hover over a run line.

    The evaluation index and additional run data is displayed as tooltips.

    Highlight run line Left-click a run line in the plot.


    Click Show Table (located above the Channel selector) to open the Parallel Coordinate Table dialog. Each run displayed in the plot is represented in a table row. Select the rows which contain the run to highlight in the plot.
    Note: Highlighting is disabled when a large number of runs is displayed.
    Tip: The Show Table option enables you to control the table channels independent of the plotted channels.

    This can be useful, for example, if you are plotting objective or constraint values and want to only see the variables that correspond to them.

    Review trends in run data Click-and-drag your mouse to draw boxes around sets of lines.

    All of the lines included in the box remain displayed, while unselected lines disappear. A visual indicator appears, and displays the minimum and maximum values for the selected set of lines.

    Multiple boxes can be drawn around sets of line to review.

    To display all of the lines, right-click in the plot and select Reset Filter from the context menu.

    In Figure 1 run data was selected for a set of lines. In Figure 2, you can see that when Styling is low, Height is high.

    Filter run data Click Show Filter (located above the Channel selector) to open the Coordinate Filter dialog.
    • From the Filter column, select the input variables and output responses to plot.
    • From the Filter Min and Filter Max columns, enter values to filter.
    The filtering mechanisms used in the Parallel Coordinate tab are interoperable, meaning the run data you have selected using box selection in the work area will be selected in the Coordinate Filter dialog, and visa versa.
Configure the parallel coordinate plot's display settings by clicking (located above the Channel selector). For more information about these settings, refer to Parallel Coordinate Tab Settings.

Parallel Coordinate Tab Settings

Settings to configure the parallel coordinate plots displayed in the post processing step.

Access settings from the menu that displays when you click (located above the Channel selector).
Absolute Scale
Enable an absolute scale versus a relative scale, which is used by default.
Show min/max
Turn the display of min and max ranges on and off.
Show Constraints
Marks responses with constraint definition.
Show Best Points
Accentuate the best optimum run or runs. Dial tolerance value to add alternative optimum runs.
