Pictorial

Express state through the filled portion of a familiar shape.

sy-pictorial-chart

Use in dashboards and infographics explaining a small number of metrics.

Readers may confuse area with height. Include numeric values and units.

Base chart tier: Community. Features such as additional renderers and custom branding have separate entitlement requirements.

InputData description
