Learning to Data

The chart type can be used to show patterns over time and relationships between variables. This is a comprehensive introduction to making them using two common libraries.

Layout multiple charts in a single view. Then adjust the scales appropriately for maximum comparability and a unified graphic.

Layering time series data or distributions with this method can change the feel and aesthetic versus a multi-line chart or small multiples. In some cases, frequency trails let you show more in less space.

Fill areas with varying line density to give more or less visual attention. With geographic maps, the technique is especially useful to adjust for population density.

Visualize rankings over time instead of absolute values to focus on order instead of the magnitude of change.
