Bar charts use the amCharts 5 `XYChart` and `ColumnSeries` classes. All three Anvil2 themes apply design-token-based colors and chart styling automatically.

<Note>
  For design guidelines on bar charts, see [Bar Charts design guidelines](/docs/web/data-visualization/bar-charts).
</Note>

## Vertical bar chart

A basic vertical bar chart uses a `CategoryAxis` on the x-axis and a `ValueAxis` on the y-axis.

<LiveCode showCode example="ext-charts-bar-vertical" fullWidth screenshot>
  ```tsx lines expandable theme={null}
  import { useLayoutEffect } from "react";
  import * as am5 from "@amcharts/amcharts5";
  import am5themes_Animated from "@amcharts/amcharts5/themes/Animated";
  import * as am5xy from "@amcharts/amcharts5/xy";
  import { ThemeMonochrome } from "@servicetitan/anvil2-ext-charts/am5";

  function App() {
    useLayoutEffect(() => {
      const data = [
        { country: "USA", value: 2025 },
        { country: "China", value: 1882 },
        { country: "Japan", value: 1809 },
        { country: "Germany", value: 1322 },
        { country: "UK", value: 1122 },
      ];

      const root = am5.Root.new("chartdiv");
      root.setThemes([am5themes_Animated.new(root), ThemeMonochrome.new(root)]);

      const chart = root.container.children.push(
        am5xy.XYChart.new(root, {
          panX: true,
          panY: true,
          wheelX: "panX",
          wheelY: "zoomX",
          paddingLeft: 0,
          paddingRight: 1,
        }),
      );

      // X axis (categories)
      const xRenderer = am5xy.AxisRendererX.new(root, {
        minGridDistance: 30,
        minorGridEnabled: true,
      });
      xRenderer.grid.template.setAll({ location: 1 });

      const xAxis = chart.xAxes.push(
        am5xy.CategoryAxis.new(root, {
          maxDeviation: 0.3,
          categoryField: "country",
          renderer: xRenderer,
          tooltip: am5.Tooltip.new(root, {}),
        }),
      );

      const yAxis = chart.yAxes.push(
        am5xy.ValueAxis.new(root, {
          maxDeviation: 0.3,
          renderer: am5xy.AxisRendererY.new(root, { strokeOpacity: 0.1 }),
        }),
      );

      // Series
      const series = chart.series.push(
        am5xy.ColumnSeries.new(root, {
          name: "Series 1",
          xAxis: xAxis,
          yAxis: yAxis,

          sequencedInterpolation: true,
          categoryXField: "country",
        }),
      );

      series.columns.template.setAll({
        tooltipText: "{categoryX}: {valueY}",
        tooltipY: am5.percent(10),
      });

      series.data.setAll(data);

      return () => root.dispose();
    }, []);

    return <div id="chartdiv" style={{ minWidth: "55rem", height: "500px" }} />;
  }

  export default App;
  ```
</LiveCode>

## Horizontal bar chart

To create a horizontal bar chart, swap the axes: use a `CategoryAxis` on the y-axis and a `ValueAxis` on the x-axis. Set `categoryYField` and `valueXField` on the series instead of `categoryXField` and `valueYField`.

<LiveCode showCode example="ext-charts-bar-horizontal" fullWidth screenshot>
  ```tsx lines expandable theme={null}
  import { useLayoutEffect } from "react";
  import * as am5 from "@amcharts/amcharts5";
  import am5themes_Animated from "@amcharts/amcharts5/themes/Animated";
  import * as am5xy from "@amcharts/amcharts5/xy";
  import { ThemeMonochrome } from "@servicetitan/anvil2-ext-charts/am5";

  function App() {
    useLayoutEffect(() => {
      // Reverse data so highest values appear at the top
      const data = [
        { country: "USA", value: 2025 },
        { country: "China", value: 1882 },
        { country: "Japan", value: 1809 },
        { country: "Germany", value: 1322 },
        { country: "UK", value: 1122 },
      ].reverse();

      const root = am5.Root.new("chartdiv");
      root.setThemes([am5themes_Animated.new(root), ThemeMonochrome.new(root)]);

      const chart = root.container.children.push(
        am5xy.XYChart.new(root, {
          panX: true,
          panY: true,
          wheelX: "panY",
          wheelY: "zoomY",
          paddingLeft: 0,
          paddingRight: 1,
        }),
      );

      // Y axis (categories — swapped from vertical)
      const yRenderer = am5xy.AxisRendererY.new(root, {
        minGridDistance: 30,
        minorGridEnabled: true,
      });
      yRenderer.grid.template.setAll({ location: 1 });

      const yAxis = chart.yAxes.push(
        am5xy.CategoryAxis.new(root, {
          maxDeviation: 0.3,
          categoryField: "country",
          renderer: yRenderer,
          tooltip: am5.Tooltip.new(root, {}),
        }),
      );
      yAxis.data.setAll(data);

      // X axis (values — swapped from vertical)
      const xAxis = chart.xAxes.push(
        am5xy.ValueAxis.new(root, {
          maxDeviation: 0.3,
          renderer: am5xy.AxisRendererX.new(root, { strokeOpacity: 0.1 }),
        }),
      );

      // Series — uses categoryYField and valueXField for horizontal orientation
      const series = chart.series.push(
        am5xy.ColumnSeries.new(root, {
          name: "Series 1",
          xAxis: xAxis,
          yAxis: yAxis,
          valueXField: "value",
          sequencedInterpolation: true,
          categoryYField: "country",
        }),
      );

      series.columns.template.setAll({
        tooltipText: "{categoryY}: {valueX}",
        tooltipY: am5.percent(90),
      });

      series.data.setAll(data);

      return () => root.dispose();
    }, []);

    return <div id="chartdiv" style={{ minWidth: "55rem", height: "500px" }} />;
  }

  export default App;
  ```
</LiveCode>

The theme detects horizontal orientation when `categoryYField` or `valueXField` is set on the series.

## Grouped bar chart

Grouped bar charts display multiple series side by side for each category. Create a separate `ColumnSeries` for each data group.

<LiveCode showCode example="ext-charts-bar-grouped" fullWidth screenshot>
  ```tsx lines expandable theme={null}
  import { useLayoutEffect } from "react";
  import * as am5 from "@amcharts/amcharts5";
  import am5themes_Animated from "@amcharts/amcharts5/themes/Animated";
  import * as am5xy from "@amcharts/amcharts5/xy";
  import { ThemeCategorical } from "@servicetitan/anvil2-ext-charts/am5";

  function App() {
    useLayoutEffect(() => {
      const data = [
        { year: "2021", europe: 2.5, namerica: 2.5, asia: 2.1, lamerica: 1.0 },
        { year: "2022", europe: 2.6, namerica: 2.7, asia: 2.2, lamerica: 0.5 },
        { year: "2023", europe: 2.8, namerica: 2.9, asia: 2.4, lamerica: 0.3 },
      ];

      const root = am5.Root.new("chartdiv");
      root.setThemes([am5themes_Animated.new(root), ThemeCategorical.new(root)]);

      const chart = root.container.children.push(
        am5xy.XYChart.new(root, {
          panX: false,
          panY: false,
          paddingLeft: 0,
          wheelX: "panX",
          wheelY: "zoomX",
          layout: root.verticalLayout,
        }),
      );

      // Legend
      const legend = chart.children.push(
        am5.Legend.new(root, {
          centerX: am5.p50,
          x: am5.p50,
        }),
      );

      // X axis with cell padding for grouped columns
      const xRenderer = am5xy.AxisRendererX.new(root, {
        cellStartLocation: 0.1,
        cellEndLocation: 0.9,
        minorGridEnabled: true,
      });
      xRenderer.grid.template.setAll({ location: 1 });

      const xAxis = chart.xAxes.push(
        am5xy.CategoryAxis.new(root, {
          categoryField: "year",
          renderer: xRenderer,
          tooltip: am5.Tooltip.new(root, {}),
        }),
      );
      xAxis.data.setAll(data);

      const yAxis = chart.yAxes.push(
        am5xy.ValueAxis.new(root, {
          renderer: am5xy.AxisRendererY.new(root, { strokeOpacity: 0.1 }),
        }),
      );

      // Create one series per data group
      function makeSeries(name: string, fieldName: string) {
        const series = chart.series.push(
          am5xy.ColumnSeries.new(root, {
            name: name,
            xAxis: xAxis,
            yAxis: yAxis,
            valueYField: fieldName,
            categoryXField: "year",
          }),
        );

        series.columns.template.setAll({
          tooltipText: "{name}, {categoryX}: {valueY}",
          width: am5.percent(90),
          tooltipY: 0,
        });

        series.data.setAll(data);
        legend.data.push(series);
      }

      makeSeries("Europe", "europe");
      makeSeries("North America", "namerica");
      makeSeries("Asia", "asia");
      makeSeries("Latin America", "lamerica");

      return () => root.dispose();
    }, []);

    return <div id="chartdiv" style={{ minWidth: "55rem", height: "500px" }} />;
  }

  export default App;
  ```
</LiveCode>

## Stacked bar chart

Stacked bar charts show how parts contribute to a whole. Set `stacked: true` on each `ColumnSeries`.

<LiveCode showCode example="ext-charts-bar-stacked" fullWidth screenshot>
  ```tsx lines expandable theme={null}
  import { useLayoutEffect } from "react";
  import * as am5 from "@amcharts/amcharts5";

  function App() {
    useLayoutEffect(() => {
      const data = [
        { year: "2021", europe: 2.5, namerica: 2.5, asia: 2.1, lamerica: 1.0 },
        { year: "2022", europe: 2.6, namerica: 2.7, asia: 2.2, lamerica: 0.5 },
        { year: "2023", europe: 2.8, namerica: 2.9, asia: 2.4, lamerica: 0.3 },
      ];

      const root = am5.Root.new("chartdiv");
      root.setThemes([am5themes_Animated.new(root), ThemeMonochrome.new(root)]);

      const chart = root.container.children.push(
        am5xy.XYChart.new(root, {
          panX: false,
          panY: false,
          wheelX: "panX",
          wheelY: "zoomX",
          paddingLeft: 0,
          layout: root.verticalLayout,
        }),
      );

      const legend = chart.children.push(
        am5.Legend.new(root, {
          centerX: am5.p50,
          x: am5.p50,
        }),
      );

      const xRenderer = am5xy.AxisRendererX.new(root, {
        cellStartLocation: 0.1,
        cellEndLocation: 0.9,
        minorGridEnabled: true,
      });
      xRenderer.grid.template.setAll({ location: 1 });

      const xAxis = chart.xAxes.push(
        am5xy.CategoryAxis.new(root, {
          categoryField: "year",
          renderer: xRenderer,
          tooltip: am5.Tooltip.new(root, {}),
        }),
      );
      xAxis.data.setAll(data);

      const yAxis = chart.yAxes.push(
        am5xy.ValueAxis.new(root, {
          min: 0,
          renderer: am5xy.AxisRendererY.new(root, { strokeOpacity: 0.1 }),
        }),
      );

      // Create stacked series — set stacked: true on each ColumnSeries
      function makeSeries(name: string, fieldName: string) {

            name: name,
            xAxis: xAxis,
            yAxis: yAxis,
            valueYField: fieldName,
            categoryXField: "year",
          }),
        );

        series.columns.template.setAll({
          tooltipText: "{name}, {categoryX}: {valueY}",
          tooltipY: am5.percent(10),
        });

        series.data.setAll(data);
        legend.data.push(series);
      }

      makeSeries("Europe", "europe");
      makeSeries("North America", "namerica");
      makeSeries("Asia", "asia");
      makeSeries("Latin America", "lamerica");

      return () => root.dispose();
    }, []);

    return <div id="chartdiv" style={{ minWidth: "55rem", height: "500px" }} />;
  }

  export default App;
  ```
</LiveCode>

## Using different themes

Change the theme import to apply a different color palette. The chart structure stays the same.

### Monochrome theme

Use `ThemeMonochrome` for data with a natural order or progression, or when displaying 4 or fewer variables. This is the default theme used in the examples above.

```tsx theme={null}
import { ThemeMonochrome } from "@servicetitan/anvil2-ext-charts/am5";

root.setThemes([
  am5themes_Animated.new(root),
  ThemeMonochrome.new(root),
]);
```

### Categorical theme

Use `ThemeCategorical` when displaying 5 or more distinct series that need maximum color differentiation.

```tsx theme={null}
import { ThemeCategorical } from "@servicetitan/anvil2-ext-charts/am5";

root.setThemes([
  am5themes_Animated.new(root),
  ThemeCategorical.new(root),
]);
```

<Warning>
  The categorical palette colors do not all meet 3:1 contrast against each other. When using `ThemeCategorical`, include direct labeling on bars to meet [accessibility requirements](/docs/web/data-visualization/accessibility).
</Warning>

### Semantic theme

Use `ThemeSemantic` when data represents status values. Colors follow the order: Success, Neutral, Warning, Danger.

```tsx theme={null}
import { ThemeSemantic } from "@servicetitan/anvil2-ext-charts/am5";

root.setThemes([
  am5themes_Animated.new(root),
  ThemeSemantic.new(root),
]);
```

## Tooltips

The theme applies tooltips that match the Anvil2 [Tooltip](/docs/web/components/tooltip/design) styling across all chart types.
