Alluvial Chart

An alluvial chart, as the name suggests, is a type of chart that represents a unidirectional stream of water branching out to form tributaries. An alluvial chart is basically a form of the Sankey chart that represents a flow chart that changes over time or dimensions. The width of the stream indicates the data values. An alluvial chart can be used to compare, correlate, distribute, identify trends over time, and shift in group composition. The blocks within the alluvial chart represent the dimensional values for each dimension used. The height of each block represents the cluster size, and the thickness of each stream is proportional to the data values connecting both connected blocks.

Note

• Keep the number of nodes/blocks to a manageable level to maintain clarity and avoid clutter.
• Differentiate entities with distinct colors and provide clear labels to ensure the chart is easy to read and interpret.
• Properly label the chart to explain what the values and timeframe.

Dont's

• Do not include too many nodes/blocks in the alluvial chart.
• Do not use alluvial chart when there is no proper hierarchical order.

4. Under the Configuration tab, select the Basic Configuration option to access the essential settings for the alluvial chart.
5. Select the Datasource from Source which the chart will pull the data from the option.
6. Choose the Measure(s) that represents the numerical values you want to display based on the type of the alluvial chart.
7. Choose the Dimension(s) that represents the categorical values you want to display based on the type of the alluvial chart.
8. Use the Date (optional) to include a date dimension in your chart, useful for showing trends over time.
9. Enable Hide Zero Values option (optional) to hide bars that have a value of zero.

Chart Customization

Customizing the alluvial chart allows you to tailor the widget appearance to meet your theme. With improved customization you can enhance the clarity on the data points, the chart aesthetics and set interactivity filters making your dashboard visually appealing also effectively communicating your data insights.

The basic customizations available for the alluvial chart are as below

• General Modify the chart’s general appearance, including the background color, borders, shadows, and drill-out choices.
• Title Enable and customize the chart title’s text, font, color, and alignment.
