Creating Animated 3D Surface Plots with Plotly in Python

3D visualizations are a powerful way to present data, and when combined with animation, they can become incredibly engaging. If you’ve ever wanted to create an animated 3D surface plot using Plotly in Python, you might run into a couple of common issues. In this guide, we’ll explore these problems and provide you with a step-by-step solution.

The Challenge

When attempting to create an animated 3D surface plot, you might face two significant issues:

Frame Update Problem: The figure only updates at the second frame when you press play.

Multiple Frame Visibility: All previous frames remain visible, leading to a cluttered plot.

These challenges can be frustrating, but don’t worry! We’ll walk through a solution that will allow you to animate your 3D surface plots seamlessly.

Solutions to Common Problems

Understanding the Code Structure

To begin addressing the issues, let's take a look at the provided code snippet for animating a 3D surface plot with Plotly:

Key Modifications

To solve the problems outlined above, you need to make a few key changes:

Remove Redundant Traces from the For Loop:

The method fig.add_trace(trace) inside the loop is adding all surface traces on top of each other, making every frame visible.

Instead, you should only add the trace of the first frame.

Adding the First Frame Trace:

After creating the frames, add only the first trace outside the loop. Here’s how you can modify the code:
