This article provides a step-by-step guide on how to display the plane number in Tecplot as you move a plane, enhancing your data visualization and analysis workflow. We'll cover several methods and troubleshooting tips.

Understanding the Challenge

Tecplot doesn't inherently display a plane's numerical index directly as you interactively move it. However, we can achieve this functionality through clever use of Tecplot's scripting capabilities or by leveraging its zone-based labeling features in conjunction with careful manipulation.

Method 1: Using Tecplot's Macro Language (Recommended)

This method offers the most dynamic and precise control. It involves creating a macro that updates a text annotation based on the plane's position and index. While requiring some programming knowledge, the result is a highly customized and efficient solution.

Step-by-Step Guide:

1. Access the Macro Window: In Tecplot, open the macro window (usually found under the "Tools" or "Macros" menu).

2. Write the Macro: The macro will need to:

   • Detect the currently active plane.
   • Retrieve the plane's index (its number in the list of planes).
   • Update a text annotation with this index. This annotation should be positioned appropriately to remain visible as the plane moves.

   Here's a sample macro (Note: this is a simplified example and may need adjustments depending on your Tecplot version and dataset):

   // Get the active plane
   activePlane = GetActivePlane()
   
   // Get the plane index (adjust as needed for your specific setup)
   planeIndex = activePlane.Index
   
   // Update the text annotation (replace "PlaneNumberAnnotation" with your annotation's name)
   SetTextAnnotation("PlaneNumberAnnotation", "Plane Number: " + planeIndex)
   

3. Create a Text Annotation: Before running the macro, create a text annotation in your Tecplot layout. Name this annotation something descriptive, like "PlaneNumberAnnotation," matching the name used in the macro.

4. Assign the Macro to a Button (Optional): For ease of use, assign the macro to a button or keyboard shortcut.

5. Test and Refine: Run the macro and move the plane. The annotation should dynamically update with the current plane number. You might need to adjust the macro code and annotation position for optimal visibility.

Method 2: Utilizing Zone Labels (Less Dynamic)

This method offers a simpler, albeit less dynamic, approach. It relies on pre-labeling zones and relies on visual identification rather than numerical display during plane movement.

Step-by-Step Guide:

1. Label Zones: Before moving planes, manually label each zone with its corresponding plane number. Use Tecplot's zone labeling features to add this information to each zone.

2. Move the Plane: As you move the plane, the associated zone label will remain visible, providing a visual indication of the plane's index. However, this label might shift position and become difficult to interpret if your plane cuts through many zones.

Troubleshooting Tips

• Macro Errors: Carefully check the macro code for syntax errors. Tecplot's macro language has specific syntax rules, so errors can easily disrupt functionality.
• Annotation Visibility: Ensure the text annotation is correctly positioned and its size is large enough for easy visibility.
• Active Plane: Verify that the macro correctly identifies the currently active plane.

Conclusion

While Tecplot doesn't offer a built-in feature to directly display a plane number during movement, utilizing macros provides a powerful and flexible solution. The macro-based approach offers a significantly improved user experience over the alternative zone labeling method, particularly when dealing with complex datasets and frequent plane manipulation. Remember to adjust the provided macro code to fit your specific dataset and Tecplot configuration.
