Understanding Bar Charts in Looker Studio
A bar chart is a graphical representation of data using rectangular bars. The length of each bar corresponds to the value it represents. Bar charts are an excellent way to compare different categories, track changes over time, and analyze trends. Looker
Studio offers two main types of bar charts:
Standard Bar Chart
Stacked Bar Chart
Each type serves a unique purpose and is best suited for specific types of data analysis.
Features of Standard Bar Charts
The standard bar chart in Looker Studio consists of separate bars that compare values across different categories. The bars can be displayed horizontally or vertically.
Key Features:
Customizable Axes: Users can modify the X and Y axes to display different metrics and dimensions.
Bar Orientation: Can be set to vertical (column chart) or horizontal (bar chart).
Multiple Data Series: Allows users to compare multiple data series within a single chart.
Color Customization: Choose from a variety of colors to differentiate data points.
Sorting Options: Sort data based on ascending or descending order.
Drill-Down Capabilities: Users can click on bars to explore deeper insights into a dataset.
Tooltips: Hovering over a bar displays additional information for better understanding.
When to Use a Standard Bar Chart
A standard bar chart is best used when comparing different categories of data. For instance, sales by product category is an excellent use case. Each product category (e.g., electronics, clothing, home appliances) is represented by a separate bar, making it easy to see which category generates the most revenue.
Features of Stacked Bar Charts
The stacked bar chart is an extension of the standard bar chart where each bar is divided into multiple segments, representing different sub-categories of data.
Key Features:
Multiple Data Series in One Bar: Instead of displaying separate bars for each series, the stacked bar chart combines them into a single bar.
Full Stacking or 100% Stacking: Can be displayed as absolute values or as percentages.
Color-coded Segments: Different colors represent different sub-categories for better visualization.
Comparison Within Categories: Users can compare total values as well as sub-category distributions.
Custom Labels and Legends: Allows for better clarity and easy understanding of data.
When to Use a Stacked Bar Chart
Stacked bar charts are ideal when you need to break down a category into its components. A good example is monthly revenue by product category where each month is represented by a bar, and different product categories are stacked within the bar. This allows businesses to see both total revenue and how much each product category contributes.
Comparison: Standard Bar Chart vs. Stacked Bar Chart
Feature | Standard Bar Chart | Stacked Bar Chart |
Best for | Comparing different categories | Comparing total values and their sub-categories |
Data Series | Separate bars for each series | Multiple series stacked in one bar |
