Dual-Axis Line Chart

A Dual-Axis Line Chart is perfect for comparing two different metrics over the same time period. By using two Y-axes, this chart provides a clear visual distinction between the data sets, making it easier to identify relationships and trends.

How To Read the Visualization

The Dual-Axis Line Chart features two Y-axes, one on the left and one on the right, each representing a different metric. The X-axis typically shows time. Lines plot the data points for each metric, with one line corresponding to each Y-axis. This allows for the simultaneous analysis of two related but distinct trends.

Data Structure

• Measures: 2 (one for each Y-axis)
• Dimensions: 1 (usually time)

Best Practices / Limitations

• Clarity: Use clearly distinguishable colors and labels for the two lines to avoid confusion.
• Balance: Ensure that the scales of the Y-axes are appropriate to avoid misleading interpretations.
• Context: Provide context or annotations to highlight significant trends or correlations between the two metrics.
