title: Dots
description: Point markers for line, area, and composed charts.

## Usage

Compose a `<Dot />` inside a `<Line />` (or `<Area />`) to render a resting marker at every data point, and an `<ActiveDot />` for the marker shown while that point is hovered. Both read the series color and style from the chart context.

```tsx
import { EChartsLineChart } from "@/components/evilcharts/charts/echarts-line-chart";

<EChartsLineChart data={data} config={chartConfig} xDataKey="month">
  <EChartsLineChart.Line dataKey="desktop">
    <EChartsLineChart.Dot variant="border" />
    <EChartsLineChart.ActiveDot variant="default" />
  </EChartsLineChart.Line>
</EChartsLineChart>;
```

## Variants

Control the marker style with the `variant` prop on the `<Dot />` (or `<ActiveDot />`) part.

`ping` is ECharts-only — a solid core wrapped in a translucent halo.

## API Reference

Both `<Dot />` (the resting marker) and `<ActiveDot />` (the hovered marker) accept the same props and are composed inside a `<Line />` or `<Area />`.


  ### `variant`

type: `"default" | "border" | "colored-border" | "ping" | "none"` · default: `"default"`

Visual style of the point marker. `<Dot>` sets the resting marker; `<ActiveDot>` sets the marker shown on hover.
