Divide space according to the number of fields, then use data to visualize in these subspaces.

Getting Started

import { Chart } from '@antv/g2';

const chart = new Chart({
  container: 'container',
  width: 300,
  height: 720,
  paddingLeft: 50,
  paddingBottom: 60,
});

const repeatMatrix = chart
  .repeatMatrix()
  .data({
    type: 'fetch',
    value: 'https://assets.antv.antgroup.com/g2/weather.json',
    transform: [
      {
        type: 'map',
        callback: ({ date, ...d }) => ({
          ...d,
          date: new Date(date).getMonth() + '',
        }),
      },
    ],
  })
  .encode('y', ['temp_max', 'precipitation', 'wind'])
  .encode('x', 'date');

repeatMatrix
  .line()
  .transform({ type: 'groupX', y: 'mean' })
  .encode('color', 'location')
  .scale('y', { zero: true });

chart.render();

Options

The underlying implementation of repeatMatrix is consistent with mark, so many configuration options are the same.

Property	Description	Type	Default
data	Refer to data for related information	`Data`
encode	Channel settings, see table below
padding	Padding size	`number`	0
paddingLeft		`number`	0
paddingRight		`number`	0
paddingTop		`number`	0
paddingBottom		`number`	0
margin	Margin	`number`	0
marginLeft		`number`	0
marginRight		`number`	0
marginTop		`number`	0
marginBottom		`number`	0
title	Refer to title for related information
scale	Refer to scale for related information

All configurations corresponding to repeatMatrix can be set using the API, for example:

chart.repeatMatrix().data([1, 2, 3]).encode('x', ['f1', 'f2', 'f3']);

encode

For repeatMatrix, there are unique encode channels.

Channel	Description	Type	Default
x	Specify the field list in the x direction for x-axis splitting	`string[]`
y	Specify the field list in the y direction for y-axis splitting	`string[]`
