- An ECharts React panel containing category dates and a smooth value series in a plain option object. It uses a warm amber palette, dotted horizontal grid lines, an axis-triggered tooltip and a transparent background.
- Canvas chart rendering without a separate WebGL engine. A ResizeObserver resizes the panel with its container, and cleanup disposes the chart instance. The component has a minimum height and accepts a className for placement.
- A separate Recharts balance-card example with headline balance, daily change, peak/trough labels, a selected reference date and custom hover formatting. This is an alternate example, not the usage entry for the ECharts panel.
- Editable component files and a visual contract covering palette, type, radius, icons and motion. Series and category labels remain data-shaped configuration that can be replaced, with project adaptation and local-asset guidance.
Before you choose
Choose this for a compact magnitude trend over labeled observations. Before styling it, define whether the value means balance, revenue or another measure and which period it covers. Then check that the line, axis, hover value and any summary all describe the same unit; a polished financial card is misleading if those values disagree.
