To customize output of nodes in a workspace :

1. Record a macro of the customization (Graph or Spreadsheet) . You may optionally save the macro to disk or deploy to Enterprise if the customization needs to be re-used for other workspaces. Leave the macro open if it is not being saved.

2. Right-click on a node within the workspace. The node must be a node that produces a spreadsheet or downstream document.In the menu that follows, select the "Customize Output" option. The Node Customization window will appear with an option to select any node currently being used in the workspace.

3. Click on New Script in the bottom pane. Select the macro recorded in Step 1. Note that you may alternatively choose a specific graph/spreadsheet output and click on the "Record Customization Script..." button to record a new macro. 

4. Give the macro an appropriate name and select if it affects Graphs or Spreadsheet output click OK. Add more scripts if required (You may customize each output differently - For example : have all graph outputs in a certain format and have all spreadsheet outputs in a different format) 

5. Drag and drop the script from the bottom pane to the upper pane where nodes are listed. Drop the script where the node needs customization. In this example, the script named changing color in graphs is being dropped on 'All graph outputs' of node "2D Means with Error Plots"

6. Similarly drag and drop the scripts to outputs as desired. and then click on the  "Apply" button.  When the node/workspace is run next, the customization scripts will automatically be applied to the output.
