Density Plot
Density plots show the distribution of a numeric variable through a continuous curve, where the area under the curve represents the probability of the variable falling within a particular range. The plot is created by applying kernel density estimation to the data.

Examples
Distribution of measurement values for categories A and B
Chart Visualization
This example includes an interactive chart visualization with 12 data points.
Chart type: density
Usage
Best Used For
- Visualizing the shape of continuous data distributions
- Comparing multiple distributions on the same scale
- Identifying modes (peaks) and skewness
- Smoother alternative to histograms
Data Requirements
[Object]
Limitations
Important Considerations
- ⚠Appearance depends on kernel and bandwidth selection
- ⚠Can smooth over fine details or gaps present in histograms
- ⚠Requires sufficient data points for accurate estimation
- ⚠Interpretation of the Y-axis (density) can be less intuitive than frequency (histogram)
