Chart Area

Area charts built on unovis-vue. One ChartArea handles single or multi-series data, with optional gradient fills and stacking.

Default

A single-series gradient area.

Multiple overlapping series, each with its own gradient fill.

Series stacked on top of each other (stacked prop).

Solid multi-series fills with both axes labelled.

Add a legend and per-series icons via the config.

Filter the visible range with a select.

A gradient area over a dashed horizontal grid.

Stacked gradient areas with per-series dashed outlines.

A step curve filled with a dotted SVG pattern.

A glowing line and dot markers via SVG filters.

Stacked areas filled with crosshatch SVG patterns.
