Add data visualization to your Bubble app using chart plugins like Chart.js or Chartmaster. This tutorial covers installing a chart plugin, connecting it to database data, configuring bar, line, pie, and donut charts, and making them responsive across screen sizes.
Overview: Creating Charts and Graphs in Bubble
Visualizing data with charts makes dashboards and reports more useful. This tutorial shows how to add charts to your Bubble app using plugins, connect them to live database data, and configure different chart types.
Prerequisites
- A Bubble account with data to visualize
- A chart plugin (Chart.js or Chartmaster)
- Basic understanding of Data Types and searches
Step-by-step guide
Install a chart plugin
Install a chart plugin
Go to the Plugins tab and search for Chart.js or Chartmaster. Install your preferred option. Chart.js is free and widely used. Chartmaster offers more chart types. Both create visual elements you can drag onto pages.
Expected result: A chart plugin installed and ready to use.
Add a chart element to your page
Add a chart element to your page
In the Design tab, click + and search for the chart element from your plugin. Drag it onto the page. Set a size of at least 400x300px. Choose the chart type: Bar for comparisons, Line for trends, Pie for proportions, or Donut for category breakdowns.
Expected result: A chart element on your page ready for data configuration.
Connect the chart to database data
Connect the chart to database data
In the chart element properties, set the Data source to a search. For a sales chart: Do a search for Orders grouped by month. Set the X-axis to the month and Y-axis to the sum of amounts. Most chart plugins accept lists of values for labels and data points that you can construct from searches.
Pro tip: Use :group by with aggregation (sum, count, average) to prepare data for charts directly in the search expression.
Expected result: The chart displays live data from your database.
Customize chart appearance
Customize chart appearance
Configure colors, labels, legends, and tooltips in the chart element properties. Set custom colors for each data series. Add axis labels. Enable tooltips that show values on hover. For brand consistency, use your app colors from Style Variables.
Expected result: A professionally styled chart matching your app design.
Make charts responsive
Make charts responsive
Set the chart element to 100% width of its parent group. Most chart plugins automatically resize. Add a min-height to prevent the chart from collapsing on mobile. Test at different breakpoints to ensure readability.
Expected result: Charts scale appropriately across desktop, tablet, and mobile.

Why it's a problem: Not aggregating data before passing to charts
How to avoid: Use :group by with sum/count aggregation in your search expression.
Why it's a problem: Overloading charts with too many data points
How to avoid: Limit to 10-15 categories. Group smaller values into an Other category.
Why it's a problem: Using the wrong chart type
How to avoid: Use Line for trends over time, Bar for comparisons, Pie for proportions of a whole.
Best practices
- Use :group by aggregation for chart data preparation
- Limit categories to 10-15 for readability
- Choose chart types based on data relationships
- Use consistent brand colors across all charts
- Add axis labels and legends for clarity
- Make charts responsive with percentage widths
