/** * @class Ext.chart.axis.Category * @extend Ext.chart.axis.Axis * @alias axis.category * * A type of axis that displays items in categories. This axis is generally used to * display categorical information like names of items, month names, quarters, etc. * but no quantitative values. For that other type of information {@link Ext.chart.axis.Numeric Numeric} * axis are more suitable. * * As with other axis you can set the position of the axis and its title. For example: * * @example packages=[charts,ext-react] * import React, { Component } from 'react'; * import { ExtReact, Container } from '@sencha/ext-react'; * import { Cartesian } from '@sencha/ext-charts'; * * export default class MyExample extends Component { * * store = new Ext.data.Store({ * fields: ['name', 'data1', 'data2', 'data3'], * data: [ * { 'name': 'metric one', 'data1': 10, 'data2': 12, 'data3': 14 }, * { 'name': 'metric two', 'data1': 7, 'data2': 8, 'data3': 16 }, * { 'name': 'metric three', 'data1': 5, 'data2': 2, 'data3': 14 }, * { 'name': 'metric four', 'data1': 2, 'data2': 14, 'data3': 6 }, * { 'name': 'metric five', 'data1': 27, 'data2': 38, 'data3': 36 } * ] * }) * * render() { * return ( * <ExtReact> * <Cartesian * store={this.store} * series={[{ * type: 'area', * xField: 'name', * yField: ['data1', 'data2', 'data3'] * }]} * axes={[{ * type: 'category', * position: 'bottom', * fields: ['name'], * title: { * text: 'Sample Values', * fontSize: 15 * } * }]} * /> * </ExtReact> * ) * } * } * * In this example with set the category axis to the bottom of the surface, bound the axis to * the `name` property and set as title "Sample Values". */
