# Axis Position

Cartesian axes can be positioned on the `top`, `bottom`, `left`, or `right` edge of the chart.

## Axis Placement

The axis `position` property controls where the axis is rendered. By default, horizontal axes appear at the bottom of the chart and vertical axes appear on the left.

#### Axis Positions

[Live example: Axis Positions](https://www.ag-grid.com/charts/archive/14.2.0/vue3/axes-position/examples/axis-position-basic/)

```js
{
    axes: {
        x: {
            type: 'category',
            position: 'bottom',
            title: { text: 'Quarter' },

            position: 'right',

        },
    },
}
```

[Secondary Axes](https://www.ag-grid.com/charts/archive/14.2.0/vue/axes-secondary/) default to the opposite edge from the primary axis, but it is possible to have multiple axes on the same edge. These are displayed alongside each other.

## Axis Crossing Point

The `crossAt` option allows an axis to intersect a perpendicular axis at a specific axis value instead of the chart edge. This is useful for centring the chart origin or aligning axes to highlight particular thresholds.

The axis title, [labels](https://www.ag-grid.com/charts/archive/14.2.0/vue/axes-labels/) and [crosshair label](https://www.ag-grid.com/charts/archive/14.2.0/vue/axes-crosshairs/) can be positioned alongside the axis or at the edge of the chart.

createApp(ChartExample).mount("#app");
```

[Live example: CrossAt](https://www.ag-grid.com/charts/archive/14.2.0/vue3/axes-position/examples/axis-cross-at/)

```js
{
    axes: {
        x: {
            type: 'number',
            // place the bottom axis at '0' on the left axis scale
            crossAt: {
                value: 0,
                titlePlacement: 'crossing',
                labelPlacement: 'crossing',
                crosshairLabelPlacement: 'edge',
            },
        },
        y: {
            type: 'number',
            // place the left axis at '0' on the bottom axis scale
            crossAt: {
                value: 0,
                titlePlacement: 'crossing',
                labelPlacement: 'crossing',
                crosshairLabelPlacement: 'edge',
            },
        },
    },
}
```

In this example:

- Both axes have a `crossAt.value` set. It is also possible to set it on a single axis only.
- The `crossAt.titlePlacement`, `crossAt.labelPlacement` and `crossAt.crosshairLabelPlacement` properties control where these elements are placed.
- The `crossAt.value` must be of the same type as the perpendicular axis domain, such as `Number` or `Date`.
- The `crossAt` target value should be within the domain of the perpendicular axis.

When the target value leaves the visible range, such as by [Zooming](https://www.ag-grid.com/charts/archive/14.2.0/vue/zoom/), the axis will stick to the edge of the chart and remain in view. Set `sticky: false` to allow the axis to be moved out of view in this scenario.

## Band Alignment

The `bandAlignment` option controls the band layout when using [fixed width bars](https://www.ag-grid.com/charts/archive/14.2.0/vue/bars/#fixed-width).

#### Band Alignment

```ts
import { createApp, defineComponent, ref } from "vue";

  BarSeriesModule,
  CategoryAxisModule,
  LegendModule,
  ModuleRegistry,
  NumberAxisModule,
} from "ag-charts-enterprise";
import { getData } from "./data";
import clone from "clone";

ModuleRegistry.registerModules([
  BarSeriesModule,
  CategoryAxisModule,
  NumberAxisModule,
  LegendModule,
]);

const ChartExample = defineComponent({
  template: `

      },
      formatter: {
        y(params) {
          const value = params.value;
          const millions = value / 1000000;
          const accuracy = ["series-label", "axis-label"].includes(
            params.source,
          )
            ? 0
            : 1;
          return `${millions.toFixed(accuracy)}M`;
        },
      },
    });
