Set discrete axes for number dimensions in PDI Data Explorer

To display Number dimensions in the line and area visualizations on a discrete axis, perform the following steps:

1. Navigate to the pentaho/design-tools/data-integration/system/karaf/config/web-client system directory and open the config.js file with any text editor.
2. Locate the Example Rule 10 - Disable the continuous number strategy code block, as shown in this example:

   // Example Rule 10 - Disable the continuous number strategy, to revert
   // to the old behavior (Before 8.2) that represents Number dimensions in a discrete axis.
   /*
   {
     select: { module: "pentaho/visual/role/adaptation/EntityWithNumberKeyStrategy" },
     apply: { isBrowsable: false }
   },
   */

3. Remove the /* marker and the */ marker to uncomment the EntityWithNumberKeyStrategy command.
4. Save and close the file, then refresh the browser.

Your line and area visualizations will display Number dimensions on a discrete axis and the scatter visualization will not be able to provide Number dimensions.
