Charts
Lower-level visx chart primitives shared by HEMS graphs and custom Spark blocks.
Spark charts are built on visx. This section covers the primitives you reach for when assembling a custom plot, or when a HEMS chart is too opinionated.
Domain charts such as Power History Chart, Energy History Chart, Solar Forecast Chart, Energy Bar Graph, and Sankey Chart live under HEMS.
Line Chart
Multi-series time plot. Requires explicit width.
Bar Chart
Stacked categorical bars with optional line overlays.
Donut Chart
Segment ring with a center label and sublabel.
Series Legend
Toggleable legend used by the composed charts.
Chart Tooltip
Shared tooltip card, measurement, and clamp helpers.
