Why Combo charts (bar + line) in Tableau? - Purpose & Use Cases

The Big Idea

What if you could instantly see how sales and profits dance together in one simple chart?

The Scenario

Imagine you have sales data and profit margins for each month. You try to show both in one report by creating separate charts and then manually comparing them side by side.

The Problem

This manual way is slow and confusing. You have to look back and forth between charts, making it easy to miss important trends or relationships. Updating data means redoing everything.

The Solution

Combo charts let you combine bars and lines in one view. You can see sales as bars and profit margin as a line on the same timeline, making comparisons clear and quick.

Before vs After

✗ Before

Create bar chart for sales
Create line chart for profit margin
Place side by side

✓ After

Use combo chart
Set bars for sales
Set line for profit margin

What It Enables

Combo charts make it easy to spot how two related numbers move together over time in one clear picture.

Real Life Example

A store manager sees monthly sales as bars and profit margin as a line on one chart, quickly spotting months where sales were high but profits dropped.

Key Takeaways

Manual separate charts are hard to compare.

Combo charts combine bars and lines in one view.

This helps spot relationships and trends easily.
