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.
