Stacked Area Chart

This chart visualizes numerical values from multiple columns as stacked areas. Different stacking types can be chosen to guide the user's interpretation: The node can display Stacked Area Charts, Percentage Area Charts and Stream Graphs. Different interpolation methods can be chosen to give the graph an organic appearance.

The node supports custom CSS styling. You can simply put CSS rules into a single string and set it as a flow variable 'customCSS' in the node configuration dialog. You will find the list of available classes and their description on our documentation page.
