Viewing the Parallel Coordinate Graphs

You can use the Engineering Data Mining (EDM) tool to create parallel coordinate graphs that allow you to visualize all the input and output values for components that have at least two objectives.

  1. From the model explorer on the left side of the Runtime Gateway, select the component you want to examine, and click the Data Analysis tab.
  2. Click the EDM subtab.
    Isight displays the two parallel coordinate graphs on the EDM subtab.
  3. If you are analyzing an imported data file and you want to import a Pareto file, click the button located next to the button. The button appears only if you have imported a data file. For more information on importing a data file, see Importing Data from a File.

    Note: By default, file parameters are not shown. If the file parameter does not appear, click and select the Pareto file parameter. You can set a preference option to display all file parameters automatically (see Setting Preferences).

  4. Determine whether or not you want to normalize the data:
    • To normalize the data, click Normalize Data in the lower right corner of the tab. You might need to expand the Runtime Gateway to see the option. If selected, the data for each input and output are normalized by the range of the data. The data for all inputs and outputs are displayed across the full vertical range of the graphs.
    • To leave the data unnormalized, clear the Normalize Data check box. If not selected, the resulting range of the graphs is based on the smallest and largest values of all the input or output parameters. In this case, if one parameter range is 1 to 100 and another parameter range is 1 to 10, the second parameter is displayed over only 10% of the vertical range of the graph. This option allows the inputs or outputs to be compared by magnitude and range.
  5. Optional: You can control how the points appear in the graphs:
    • Set the sort options for the data in the tables by selecting the parameters on which to sort by clicking the arrow next to Run Number. . Run Number is the default. You can click to change the order of the sort (Ascending or Descending).
    • To move between runs, click the Current data point buttons of the tab. The text box shows the run for which the data is currently displayed.
    • To reduce the number of points displayed in the parallel coordinate graphs, click Data Filters in the lower left of the tab. Reducing the number of points displayed in the parallel coordinate graphs also reduces the number of points displayed on all other tabs.
    • To return the values in the graphs to their default settings, click the arrow next to and select Reset Sort.
  6. To save a data point, do the following:
    1. Click the point in either of the two graphs, right-click and select Export.
    2. Select how you want to save the data:

      Option Description
      Export to Image Save the graph as a *.jpeg, *.jpg, or *.png file.
      Export to Text File Save the graph data as a text file.
      Export to Excel Export the graph to an Excel worksheet and display it. From this point, you can manipulate the graph, as desired, using Excel. However, Excel has a 64 kilobyte row limit, which might impact your ability to export a graph.
      Export Selected to Text File Save the currently selected points to a text file.

    3. Navigate to the directory where you want to store the file, enter a file name and extension in the File Name text box, and click Save.
    The file is saved. Depending on the file type you can access it with any image viewing software or text editor.

Note: The Parallel Coordinate Graph supports parameters of types Integer, Double, and Boolean. It also supports String type parameters if the parameter has allowed values defined for it. If a String type parameter does not have allowed values defined for it, the parameter will not be included in the graph.
