Chart Component – Charts

Implementation
Chart Props
Tooltip Config
Tooltip Point Config

Common Examples

The Chart component renders an ECharts option with Anvil2 styling. Import EChartsOption from the kit to keep chart configuration on the supported public API.

import {
  Chart,
  type EChartsOption,
} from "@servicetitan/anvil2-charts-kit";
import "@servicetitan/anvil2-charts-kit/styles.css";

const option: EChartsOption = {
  xAxis: { type: "category", data: ["North", "South", "East", "West"] },
  yAxis: { type: "value" },
  series: [{ type: "bar", data: [1200, 980, 1450, 1100] }],
};

function ExampleComponent() {
  return <Chart option={option} />;
}

Chart defaults to appearance="light" and variant="monochrome". Set appearance to match the surrounding theme.

Tooltips

Pass renderTooltip to provide tooltip content. The chart controls placement and keeps the tooltip within the plot.Omit renderTooltip when the chart does not need a tooltip. Format each value for its product context.

Palette utilities

Use variant when colors follow the palette’s index order. The variant applies fills, borders, patterns, markers, corner treatments, and hover behavior.

<Chart option={option} variant="categorical" />

Use chartPalette when an option needs a specific palette entry. chartStepItemStyle converts monochrome and semantic steps into ECharts itemStyle values.

import {
  chartPalette,
  chartStepItemStyle,
} from "@servicetitan/anvil2-charts-kit";

const palette = chartPalette("light", "semantic");

const option: EChartsOption = {
  series: [
    {
      type: "bar",
      data: [1200],
      itemStyle: chartStepItemStyle(palette.danger.primary),
    },
  ],
};

Consumer-defined itemStyle values override variant styling.

<Chart
  option={option}
  variant="monochrome"
  width={480}
  height={300}
/>
