multibar

Multibar is a term used in data visualization and interface design to describe an element that uses multiple bars to convey information. The exact meaning of multibar varies by context, and it is not a standardized term across fields.

In data visualization, multibar can refer to a multibar chart, a variant of the bar chart that displays several series within each category. This can take the form of grouped bars, where bars for different series appear side by side, or stacked bars, where series values are stacked in a single bar. Multibar charts are used to compare multiple data series across categories such as time periods, regions, or demographic groups.

In user interface design, a multibar may describe a toolbar, status bar, or control panel that aggregates several independent controls or indicators into one horizontal or vertical bar. Such multibars are common in dashboards, editors, and software applications where space efficiency and quick access to tools are important.

In physical or digital meters, multibar displays show several separate bars representing different metrics or levels, for example in audio level meters or system health indicators.

Limitations: Because multibar is not a precise, widely standardized term, its meaning can be ambiguous. When precision is required, it is common to use more specific terminology, such as grouped bar chart, stacked bar chart, or toolbar.
