How to Make Sure the Range Selector in Plotly Only Appears Once in Your Dashboard

Creating an effective dashboard can become challenging, especially when it comes to managing visual elements like range selectors in Plotly subplots. If you’ve ever found yourself frustrated with repeated range selector buttons across your charts, you’re not alone. Many users encounter this issue, which can lead to a cluttered interface and a less-than-ideal user experience. In this guide, we'll explore a solution to this common problem and show you how to customize your Plotly charts for better clarity and usability.

The Problem

Imagine you have a dashboard featuring multiple subplots, and you've implemented a range selector to help users navigate through data over specific time periods. The issue arises when these range selector buttons appear in every subplot instead of just once at the top. This redundancy not only takes up valuable space but also distracts from the main visualizations.

In this case, the user specifically wants the range selector to appear only in the first subplot, avoiding repetition in subsequent rows.

The Solution

Step-by-Step Approach

To ensure that the range selector only appears once in your desired chart, we can make simple adjustments to the Plotly code. Below is a clear guide with revised code snippets to achieve this.

Define Your Subplots: Begin by creating your subplots as you normally would. For this example, we will create two rows of plots.

Explanation of Key Changes

rangeselector: This is the main component where you define the buttons. They will now only show up on the first subplot where the primary x-axis is defined.

row and col: Make sure to add row and col properties properly in your add_trace method to ensure that traces are assigned correctly without needing a range selector for each subplot.

Conclusion

By following these steps, you’ll create a cleaner, more user-friendly dashboard without the clutter of repeated range selector buttons. This approach not only enhances the aesthetic of your charts but also improves user navigation. Give it a try, and let your data visuals shine!
