# Interaction Modes

This sample shows how to use the tooltip position mode setting.

```js chart-editor
// <block:actions:2>
const actions = [
  {
    name: 'Mode: index',
    handler(chart) {
      chart.options.interaction.axis = 'xy';
      chart.options.interaction.mode = 'index';
      chart.update();
    }
  },
  {
    name: 'Mode: dataset',
    handler(chart) {
      chart.options.interaction.axis = 'xy';
      chart.options.interaction.mode = 'dataset';
      chart.update();
    }
  },
  {
    name: 'Mode: point',
    handler(chart) {
      chart.options.interaction.axis = 'xy';
      chart.options.interaction.mode = 'point';
      chart.update();
    }
  },
  {
    name: 'Mode: nearest',
    handler(chart) {
      chart.options.interaction.axis = 'xy';
      chart.options.interaction.mode = 'nearest';
      chart.update();
    }
  },
  {
    name: 'Mode: x',
    handler(chart) {
      chart.options.interaction.mode = 'x';
      chart.update();
    }
  },
  {
    name: 'Mode: y',
    handler(chart) {
      chart.options.interaction.mode = 'y';
      chart.update();
    }
  },
  {
    name: 'Toggle Intersect',
    handler(chart) {
      chart.options.interaction.intersect = !chart.options.interaction.intersect;
      chart.update();
    }
  },
];
// </block:actions>

// <block:setup:1>
const DATA_COUNT = 7;
