Data visualization is a powerful way to communicate insights, trends, and performance metrics. Whether you’re working in finance, marketing, or any data-driven field, visualizing data can make complex information easier to understand. Metabase, an open-source business intelligence (BI) tool, simplifies the process of accessing and visualizing data. This guide will take you through the steps of setting up Metabase, connecting to a data source, building queries, and creating visualizations and dashboards.
What is Metabase ?
Metabase is a user-friendly tool that enables data exploration and visualization. It provides a straightforward interface for querying databases, generating charts, and creating dashboards. Metabase supports various databases like MySQL, PostgreSQL, MongoDB, and more.
What is a Dashboard ?
A dashboard is a visual display of key information and data, often used to track, analyze, and present business metrics, trends, and insights in a user-friendly way.
A dashboard is a grid of cards that can display:
Questions: Visuals like charts, tables, or maps.
Text and Header Cards: For titles or explanations.
Link Cards: Navigating to other dashboards or websites.
You can add filter widgets to apply filters across multiple visuals and customize interactions, such as what happens when users click on charts or tables.
How to Create a Dashboard in Metabase
Dashboards are an essential part of data analysis, providing an easy-to-understand visual summary of key metrics. Metabase, an open-source business intelligence (BI) tool, makes creating and sharing dashboards straightforward. In this post, we will walk you through the process of building a dashboard in Metabase, including adding visualizations, customizing layouts, and sharing insights.
Why Use Dashboards in Metabase?
Dashboards are used to bring together multiple data visualizations into a single, interactive view. With Metabase, you can:
Combine different charts and tables in one place.
Allow stakeholders to explore data without writing queries.
Make data-driven decisions with real-time insights.
Customize filters and layout to focus on specific KPIs (Key Performance Indicators).
Prerequisites
Before you start, make sure you have:
A running Metabase instance.
Access to a connected data source (e.g., MySQL, PostgreSQL, or any other supported database).
Step-by-Step Guide to Creating a Dashboard
Step 1: Access the Dashboard Section
Log into Metabase.
From the homepage, click on the + NEW tab in the top navigation menu.
Click Dashboard to start creating your dashboard.
Step 2: Give Your Dashboard a Name
Metabase will prompt you to name your dashboard. Choose a name that describes the purpose or key metrics the dashboard will display (e.g., "Sales Performance Dashboard" or "Marketing Overview").
Step 3: Add Your Questions (Data Visualizations)
In the top-right corner of your dashboard, click the “New” button, and from the dropdown menu, select “Question”.
select the database name followed by the table name for which you want to create a question
This will open the question builder where you can create new data visualizations.
Step 4: Join Tables (if required)
If your query spans multiple tables, you can join the tables within the question builder.
Click on “Join Data” and select the related table you want to join with your primary table.
Specify the join condition (e.g., using a foreign key) to connect the tables. Ensure you are joining tables based on a common field (e.g., user_id, order_id) to get meaningful data.
Step 5: Summarize Your Data:
click on the “Summarize” button to aggregate or group your data.
This step allows you to generate summary metrics like totals, averages, counts, etc., based on your data fields.
Example: If you're looking at sales data, you might want to summarize it by sum of sales amount grouped by month or product category.Summarize Options:
Sum: Total of a numerical field (e.g., total sales).
Count: Number of entries (e.g., number of orders).
Average: Average of a numerical field (e.g., average transaction value).
Group by: Group data by a specific field (e.g., group sales by region or product type).
Step 6: Choose a Visualization Type
Bar chart, line chart, pie chart, table, or map, depending on the data.
Once your data is summarized, select a visualization type that best suits your data presentation needs. Metabase offers a variety of chart types, including:
Bar Chart: Ideal for comparing quantities across categories.
Line Chart: Great for tracking changes over time.
Pie Chart: Useful for showing proportions of a whole.
Table: To display raw data.
Map: For geographical visualizations.
Step 7: Save the question to the Dashboard
Save the Question
Once you're satisfied with the question and visualization, click “Save”.
Name your question appropriately (e.g., “Monthly Sales by Region”) for easy identification later.
Add the Questions to Your Dashboard
After saving, you will have the option to add the question directly to your dashboard.
Click “Add to Dashboard”, and the visualization will appear as a new tile on the dashboard layout.
Step 8: Add Dashboard Filters
Filters allow viewers to interact with the dashboard by selecting different parameters like dates, categories, or locations. Here’s how you add filters:
Click the Add a filter button in the top right of the dashboard.
Choose the type of filter you want to add:
Date filter
Category filter
Location filter, etc.
Once added, link the filter to specific questions on the dashboard. For example, if you add a date filter, you can configure it to update all the charts and tables that show data over time.
Step 9: Customize Your Visualization
After selecting your visualization, you can further customize it:
Change the chart’s colors.
Modify axis labels and legends for clarity.
Add tooltips to provide more context when users hover over data points.
Step 10 : Sharing and Collaboration
After creating your dashboard, you’ll want to share it with others or collaborate with your team.
Sharing a Dashboard Link
Click the Share button at the top right of the dashboard.
You’ll see options to share a direct link with colleagues. Set permissions (e.g., view-only) to control access.
Embedding Dashboards
Metabase provides the option to embed dashboards in external websites or applications. This is useful if you want to integrate the dashboard into internal tools or share it publicly.
In the Share menu, click Embed this dashboard.
You’ll get an iframe code that you can embed into a Atman Applications.
Conclusion
Creating a dashboard in Metabase is a straightforward process that can deliver immediate value. With the right combination of data visualizations, filters, and customization, you can build powerful dashboards that help your team make data-driven decisions. Whether you’re tracking sales, monitoring website traffic, or analyzing customer data, Metabase makes it easy to pull insights from your database and present them in a visually appealing format.
