Overview

Concrete panel classes for configuring Evidently monitoring dashboard visualizations provided by the Evidently library.

Description

Dashboard panel classes from the legacy UI module:

• DashboardPanelCounter: Displays a single aggregated value (NONE/SUM/LAST)
• DashboardPanelPlot: Displays time-series plots (LINE/BAR/SCATTER)
• DashboardPanelDistribution (alias DashboardPanelHistogram): Distribution histograms
• DashboardPanelTestSuite: Test result aggregation panels
• PanelValue: Helper that references a specific metric field for panel display

Usage

Import panel classes and add them to a Project's dashboard via project.dashboard.add_panel().
