Introducing Charts. A collection of chart components that you can copy and paste into your apps.

Charts are designed to look great out of the box. They work well with other components are are fully customizable to fit your project.

Component

We use LayerChart under the hood.

We designed the Chart component with composition in mind. You build your charts using LayerChart components and only bring in custom components, such as ChartTooltip, when and where you need it

<script lang="ts">
  import * as Chart from "$lib/components/ui/chart/index.js";
  import { BarChart } from "layerchart";
 
  const data = [
    // ...
  ];
</script>
 
<Chart.Container>
  <BarChart {data} x="date" y="value">
    {#snippet tooltip()}
      <Chart.Tooltip />
    {/snippet}
  </BarChart>
</Chart.Container>

We do not wrap LayerChart. This means you're not locked into an abstraction. When a new LayerChart version is released, you can follow the official upgrade path to upgrade your charts.

The components are yours.

Copy and paste the following code into your project.

Your First Chart

Let's build your first chart. We'll build a bar chart with an axis, grid, tooltip, and legend.

Start by defining your data

The following data represents the number of desktop and mobile users for each month.

Note: Your data can be in any shape. You are not limited to the shape of the data below. Use the dataKey prop to map your data to the chart.

lib/components/example-chart.svelte

<script lang="ts">
  const chartData = [
    { month: "January", desktop: 186, mobile: 80 },
    { month: "February", desktop: 305, mobile: 200 },
    { month: "March", desktop: 237, mobile: 120 },
    { month: "April", desktop: 73, mobile: 190 },
    { month: "May", desktop: 209, mobile: 130 },
    { month: "June", desktop: 214, mobile: 140 },
  ];
</script>

Define your chart config

The chart config holds configuration for the chart. This is where you place human-readable strings, such as labels, icons, and color tokens for theming.

lib/components/example-chart.svelte

<script lang="ts">
  import * as Chart from "$lib/components/ui/chart/index.js";
 
  const chartConfig = {
    desktop: {
      label: "Desktop",
      color: "#2563eb",
    },
    mobile: {
      label: "Mobile",
      color: "#60a5fa",
    },
  } satisfies Chart.ChartConfig;
</script>

Build your chart

You can now build your chart using LayerChart components. We're using the BarChart component in this example, which is one of LayerChart's "Simplified Charts".

These components handle a lot of the common chart scaffolding for you, while allowing you to customize them to your liking.

<script lang="ts">
  import { cn, type WithElementRef } from "$lib/utils.js";
  import type { HTMLAttributes } from "svelte/elements";
  import ChartStyle from "./chart-style.svelte";
  import { setChartContext, type ChartConfig } from "./chart-utils.js";

  const uid = $props.id();

  let {
    ref = $bindable(null),
    id = uid,
    class: className,
    children,
    config,
    ...restProps
  }: WithElementRef<HTMLAttributes<HTMLElement>> & {
    config: ChartConfig;
  } = $props();

  const chartId = `chart-${id || uid.replace(/:/g, "")}`;

  setChartContext({
    get config() {
      return config;
    },
  });
</script>

<div
  bind:this={ref}
  data-chart={chartId}
  data-slot="chart"
  class={cn(
    "flex aspect-video justify-center overflow-visible text-xs",
    // Overrides
    //
    // Stroke around dots/marks when hovering
    "[&_.lc-highlight-point]:stroke-transparent",
    // override the default stroke color of lines
    "[&_.lc-line]:stroke-border/50",

    // by default, layerchart shows a line intersecting the point when hovering, this hides that
    "[&_.lc-highlight-line]:stroke-0",

    // by default, when you hover a point on a stacked series chart, it will drop the opacity
    // of the other series, this overrides that
    "[&_.lc-area-path]:opacity-100 [&_.lc-highlight-line]:opacity-100 [&_.lc-highlight-point]:opacity-100 [&_.lc-spline-path]:opacity-100 [&_.lc-text]:text-xs [&_.lc-text-svg]:overflow-visible",

    // We don't want the little tick lines between the axis labels and the chart, so we remove
    // the stroke. The alternative is to manually disable `tickMarks` on the x/y axis of every
    // chart.
    "[&_.lc-axis-tick]:stroke-0",

    // We don't want to display the rule on the x/y axis, as there is already going to be
    // a grid line there and rule ends up overlapping the marks because it is rendered after
    // the marks
    "[&_.lc-rule-x-line:not(.lc-grid-x-rule)]:stroke-0 [&_.lc-rule-y-line:not(.lc-grid-y-rule)]:stroke-0",
    "[&_.lc-grid-x-radial-line]:stroke-border [&_.lc-grid-x-radial-circle]:stroke-border",
    "[&_.lc-grid-y-radial-line]:stroke-border [&_.lc-grid-y-radial-circle]:stroke-border",

    // Legend adjustments
    "[&_.lc-legend-swatch-button]:items-center [&_.lc-legend-swatch-button]:gap-1.5",
    "[&_.lc-legend-swatch-group]:items-center [&_.lc-legend-swatch-group]:gap-4",
    "[&_.lc-legend-swatch]:size-2.5 [&_.lc-legend-swatch]:rounded-[2px]",

    // Labels

    // Tick labels on th x/y axes

    "[&_.lc-tooltip-rects-g]:fill-transparent",

  {...restProps}
>
  <ChartStyle id={chartId} {config} />
  {@render children?.()}
</div>

<script lang="ts">
  import * as Chart from "$lib/components/ui/chart/index.js";
  import { scaleBand } from "d3-scale";
  import { BarChart } from "layerchart";
 
  const chartData = [
    { month: "January", desktop: 186, mobile: 80 },
    { month: "February", desktop: 305, mobile: 200 },
    { month: "March", desktop: 237, mobile: 120 },
    { month: "April", desktop: 73, mobile: 190 },
    { month: "May", desktop: 209, mobile: 130 },
    { month: "June", desktop: 214, mobile: 140 }
  ];
 
  const chartConfig = {
    desktop: {
      label: "Desktop",
      color: "#2563eb"
    },
    mobile: {
      label: "Mobile",
      color: "#60a5fa"
    }
  } satisfies Chart.ChartConfig;
</script>
 
<Chart.Container config={chartConfig} class="min-h-[200px] w-full">
  <BarChart
    data={chartData}
    xScale={scaleBand().padding(0.25)}
    x="month"
    axis="x"
    seriesLayout="group"
    tooltip={false}
    series={[
      {
        key: "desktop",
        label: chartConfig.desktop.label,
        color: chartConfig.desktop.color
      },
      {
        key: "mobile",
        label: chartConfig.mobile.label,
        color: chartConfig.mobile.color
      }
    ]}
  />
</Chart.Container>

We now have a group-stacked bar chart with an x axis and a grid.

Adjusting the Axis Ticks

Our bar chart is currently displaying the full month name for each tick on the x axis. Let's shorten it to just the first three letters.

Add a custom formatter to the x axis

The props prop is how you can pass custom props to the various components that make up the chart. Here we're passing a custom formatter to the x axis.

<Chart.Container config={chartConfig} class="min-h-[200px] w-full">
  <BarChart
    data={chartData}
    xScale={scaleBand().padding(0.25)}
    x="month"
    axis="x"
    tooltip={false}
    seriesLayout="group"
    series={[
      {
        key: "desktop",
        label: chartConfig.desktop.label,
        color: chartConfig.desktop.color,
      },
      {
        key: "mobile",
        label: chartConfig.mobile.label,
        color: chartConfig.mobile.color,
      },
    ]}
    props={{
      xAxis: {
        format: (d) => d.slice(0, 3),
      },
    }}
  />
</Chart.Container>

<script lang="ts">
  import * as Chart from "$lib/components/ui/chart/index.js";
  import { scaleBand } from "d3-scale";
  import { BarChart } from "layerchart";
 
  const chartData = [
    { month: "January", desktop: 186, mobile: 80 },
    { month: "February", desktop: 305, mobile: 200 },
    { month: "March", desktop: 237, mobile: 120 },
    { month: "April", desktop: 73, mobile: 190 },
    { month: "May", desktop: 209, mobile: 130 },
    { month: "June", desktop: 214, mobile: 140 }
  ];
 
  const chartConfig = {
    desktop: {
      label: "Desktop",
      color: "#2563eb"
    },
    mobile: {
      label: "Mobile",
      color: "#60a5fa"
    }
  } satisfies Chart.ChartConfig;
</script>
 
<Chart.Container config={chartConfig} class="min-h-[200px] w-full">
  <BarChart
    data={chartData}
    xScale={scaleBand().padding(0.25)}
    x="month"
    axis="x"
    tooltip={false}
    seriesLayout="group"
    series={[
      {
        key: "desktop",
        label: chartConfig.desktop.label,
        color: chartConfig.desktop.color
      },
      {
        key: "mobile",
        label: chartConfig.mobile.label,
        color: chartConfig.mobile.color
      }
    ]}
    props={{
      xAxis: {
        format: (d) => d.slice(0, 3)
      }
    }}
  />
</Chart.Container>

So far we've only used the BarChart component from LayerChart. They look great out of the box thanks to some customizations in the chart component.

To add a tooltip, we'll use the custom Chart.Tooltip component from chart.

Add the `Chart.Tooltip` component to the chart

We'll replace the tooltip={false} prop with the tooltip snippet where we'll place the Chart.Tooltip component.

<Chart.Container config={chartConfig} class="min-h-[200px] w-full">
  <BarChart
    data={chartData}
    xScale={scaleBand().padding(0.25)}
    x="month"
    axis="x"
    seriesLayout="group"
    series={[
      {
        key: "desktop",
        label: chartConfig.desktop.label,
        color: chartConfig.desktop.color,
      },
      {
        key: "mobile",
        label: chartConfig.mobile.label,
        color: chartConfig.mobile.color,
      },
    ]}
    props={{
      xAxis: {
        format: (d) => d.slice(0, 3),
      },
    }}
  >
    {#snippet tooltip()}
      <Chart.Tooltip />
    {/snippet}
  </BarChart>
</Chart.Container>

<script lang="ts">
  import * as Chart from "$lib/components/ui/chart/index.js";
  import { scaleBand } from "d3-scale";
  import { BarChart } from "layerchart";
 
  const chartData = [
    { month: "January", desktop: 186, mobile: 80 },
    { month: "February", desktop: 305, mobile: 200 },
    { month: "March", desktop: 237, mobile: 120 },
    { month: "April", desktop: 73, mobile: 190 },
    { month: "May", desktop: 209, mobile: 130 },
    { month: "June", desktop: 214, mobile: 140 }
  ];
 
  const chartConfig = {
    desktop: {
      label: "Desktop",
      color: "#2563eb"
    },
    mobile: {
      label: "Mobile",
      color: "#60a5fa"
    }
  } satisfies Chart.ChartConfig;
</script>
 
<Chart.Container config={chartConfig} class="min-h-[200px] w-full">
  <BarChart
    data={chartData}
    xScale={scaleBand().padding(0.25)}
    x="month"
    axis="x"
    seriesLayout="group"
    series={[
      {
        key: "desktop",
        label: chartConfig.desktop.label,
        color: chartConfig.desktop.color
      },
      {
        key: "mobile",
        label: chartConfig.mobile.label,
        color: chartConfig.mobile.color
      }
    ]}
  >
    {#snippet tooltip()}
      <Chart.Tooltip />
    {/snippet}
  </BarChart>
</Chart.Container>

Add Legend

Set the `legend` prop to `true`

The legend prop is used to show a legend for the chart. We are working with LayerChart to add a payload similar to the tooltip so we can more easily create a custom legend.

<Chart.Container config={chartConfig} class="min-h-[200px] w-full">
  <BarChart
    data={chartData}
    xScale={scaleBand().padding(0.25)}
    x="month"
    axis="x"
    seriesLayout="group"
    legend
    series={[
      {
        key: "desktop",
        label: chartConfig.desktop.label,
        color: chartConfig.desktop.color,
      },
      {
        key: "mobile",
        label: chartConfig.mobile.label,
        color: chartConfig.mobile.color,
      },
    ]}
    props={{
      xAxis: {
        format: (d) => d.slice(0, 3),
      },
    }}
  >
    {#snippet tooltip()}
      <Chart.Tooltip />
    {/snippet}
  </BarChart>
</Chart.Container>

<script lang="ts">
  import * as Chart from "$lib/components/ui/chart/index.js";
  import { scaleBand } from "d3-scale";
  import { BarChart } from "layerchart";
 
  const chartData = [
    { month: "January", desktop: 186, mobile: 80 },
    { month: "February", desktop: 305, mobile: 200 },
    { month: "March", desktop: 237, mobile: 120 },
    { month: "April", desktop: 73, mobile: 190 },
    { month: "May", desktop: 209, mobile: 130 },
    { month: "June", desktop: 214, mobile: 140 }
  ];
 
  const chartConfig = {
    desktop: {
      label: "Desktop",
      color: "#2563eb"
    },
    mobile: {
      label: "Mobile",
      color: "#60a5fa"
    }
  } satisfies Chart.ChartConfig;
</script>
 
<Chart.Container config={chartConfig} class="min-h-[200px] w-full">
  <BarChart
    data={chartData}
    xScale={scaleBand().padding(0.25)}
    x="month"
    axis="x"
    seriesLayout="group"
    legend
    series={[
      {
        key: "desktop",
        label: chartConfig.desktop.label,
        color: chartConfig.desktop.color
      },
      {
        key: "mobile",
        label: chartConfig.mobile.label,
        color: chartConfig.mobile.color
      }
    ]}
  >
    {#snippet tooltip()}
      <Chart.Tooltip />
    {/snippet}
  </BarChart>
</Chart.Container>

Done. You've built your first chart! What's next?

Chart Config

The chart config is where you define the labels, icons and colors for a chart.

It is intentionally decoupled from chart data.

This allows you to share config and color tokens between charts. It can also works independently for cases where your data or color tokens live remotely or in a different format.

<script lang="ts">
  import MonitorIcon from "@lucide/svelte/icons/monitor";
  import * as Chart from "$lib/components/ui/chart/index.js";
 
  const chartConfig = {
    desktop: {
      label: "Desktop",
      icon: MonitorIcon,
      // A color like 'hsl(220, 98%, 61%)' or 'var(--color-name)'
      color: "#2563eb",
      // OR a theme object with 'light' and 'dark' keys
      theme: {
        light: "#2563eb",
        dark: "#dc2626",
      },
    },
  } satisfies Chart.ChartConfig;
</script>

Theming

Charts has built-in support for theming. You can use css variables (recommended) or color values in any color format, such as hex, hsl, or oklch.

CSS Variables

Define your colors in your css file

src/routes/layout.css

:root {
  --background: oklch(1 0 0);
  --foreground: oklch(0.145 0 0);
  /* ... */
  --chart-1: oklch(0.646 0.222 41.116);
  --chart-2: oklch(0.6 0.118 184.704);
}
 
.dark {
  --background: oklch(0.145 0 0);
  --foreground: oklch(0.985 0 0);
  /* ... */
  --chart-1: oklch(0.488 0.243 264.376);
  --chart-2: oklch(0.696 0.17 162.48);
}

Add the color to your `chartConfig`

<script lang="ts">
  const chartConfig = {
    desktop: {
      label: "Desktop",
      color: "var(--chart-1)",
    },
    mobile: {
      label: "Mobile",
      color: "var(--chart-2)",
    },
  } satisfies Chart.ChartConfig;
</script>

hex, hsl or oklch

You can also define your colors directly in the chart config. Use the color format you prefer.

<script lang="ts">
  const chartConfig = {
    desktop: {
      label: "Desktop",
      color: "#2563eb",
    },
  } satisfies Chart.ChartConfig;
</script>

Using Colors

To use the theme colors in your chart, reference the colors using the format var(--color-KEY).

Components

<Bar fill="var(--color-desktop)" />

Chart Data

const chartData = [
  { browser: "chrome", visitors: 275, color: "var(--color-chrome)" },
  { browser: "safari", visitors: 200, color: "var(--color-safari)" },
];

Tailwind

<Label class="fill-(--color-desktop)" />

A chart tooltip contains a label, name, indicator and value. You can use a combination of these to customize your tooltip.

You can turn on/off any of these using the hideLabel, hideIndicator props and customize the indicator style using the indicator prop.

Use labelKey and nameKey to use a custom key for the tooltip label and name.

Chart comes with the <Chart.Tooltip> component. You can use this component to add custom tooltips to your chart.

Props

Use the following props to customize the tooltip.

Prop	Type	Description
`labelKey`	string	The config or data key to use for the label.
`nameKey`	string	The config or data key to use for the name.
`indicator`	`dot` `line` or `dashed`	The indicator style for the tooltip.
`hideLabel`	boolean	Whether to hide the label.
`hideIndicator`	boolean	Whether to hide the indicator.
`label`	string	A custom label for the tooltip
`labelFormatter`	function	A function to format the label.
`formatter`	Snippet	A snippet to provide flexible rendering of the tooltip.

Colors

Colors are automatically referenced from the chart config.

Custom

To use a custom key for tooltip label and names, use the labelKey and nameKey props.

<script lang="ts">
  const chartData = [
    { browser: "chrome", visitors: 187, color: "var(--color-chrome)" },
    { browser: "safari", visitors: 200, color: "var(--color-safari)" },
  ];
 
  const chartConfig = {
    visitors: {
      label: "Total Visitors",
    },
    chrome: {
      label: "Chrome",
      color: "var(--chart-1)",
    },
    safari: {
      label: "Safari",
      color: "var(--chart-2)",
    },
  } satisfies ChartConfig;
</script>
 
<Chart.Tooltip labelKey="visitors" nameKey="browser" />

This will use Total Visitors for label and Chrome and Safari for the tooltip names.
