Example 1
let Canvas = require('canvas'); let echarts = require('echarts'); echarts.setCanvasCreator(function () { // Small size is enough. return new Canvas(32, 32); });

contain: (coord: number) => boolean;

If axis extent contain given coord

method containData

containData: (data: ScaleDataValue) => boolean;

If axis extent contain given data

method getBandWidth

method getTicksCoords

getTicksCoords: (opt?: { tickModel?: Model; clamp?: boolean }) => TickCoord[];

method getDefaultOption

getDefaultOption: () => Opt;

[How to declare defaultOption]:

(A) If using class declaration in typescript (since echarts 5):

import {ComponentOption} from '../model/option.js';
export interface XxxOption extends ComponentOption {
    aaa: number
}
export class XxxModel extends Component {
    static type = 'xxx';
    static defaultOption: XxxOption = {
        aaa: 123
    }
}
Component.registerClass(XxxModel);

import {inheritDefaultOption} from '../util/component.js';
import {XxxModel, XxxOption} from './XxxModel.js';
export interface XxxSubOption extends XxxOption {
    bbb: number
}
class XxxSubModel extends XxxModel {
    static defaultOption: XxxSubOption = inheritDefaultOption(XxxModel.defaultOption, {
        bbb: 456
    })
    fn() {
        let opt = this.getDefaultOption();
        // opt is {aaa: 123, bbb: 456}
    }
}

(B) If using class extend (previous approach in echarts 3 & 4):

let XxxComponent = Component.extend({
    defaultOption: {
        xx: 123
    }
})

let XxxSubComponent = XxxComponent.extend({
    defaultOption: {
        yy: 456
    },
    fn: function () {
        let opt = this.getDefaultOption();
        // opt is {xx: 123, yy: 456}
    }
})

Data filter

method get

get: (dim: SeriesDimensionName, idx: number) => ParsedValue;

Get value. Return NaN if idx is out of range.
Should better to use data.getStore().get(dimIndex, dataIdx) instead.

method getApproximateExtent

getApproximateExtent: (dim: SeriesDimensionLoose) => [number, number];

PENDING: In fact currently this function is only used to short-circuit the calling of scale.unionExtentFromData when data have been filtered by modules like "dataZoom". scale.unionExtentFromData is used to calculate data extent for series on an axis, but if a "axis related data filter module" is used, the extent of the axis have been fixed and no need to calling scale.unionExtentFromData actually. But if we add "custom data filter" in future, which is not "axis related", this method may be still needed.
Optimize for the scenario that data is filtered by a given extent. Consider that if data amount is more than hundreds of thousand, extent calculation will cost more than 10ms and the cache will be erased because of the filtering.

method getByRawIndex

getByRawIndex: (dim: SeriesDimensionName, rawIdx: number) => ParsedValue;

Should better to use data.getStore().getByRawIndex(dimIndex, dataIdx) instead.

method getCalculationInfo

getCalculationInfo: <CALC_INFO_KEY extends keyof DataCalculationInfo<HostModel>>(
    key: CALC_INFO_KEY
) => DataCalculationInfo<HostModel>[CALC_INFO_KEY];

method getDataExtent

getDataExtent: (dim: DimensionLoose) => [number, number];

method getDimension

getDimension: (dim: SeriesDimensionLoose) => DimensionName;

Get concrete dimension name by dimension name or dimension index. If input a dimension name, do not validate whether the dimension name exits.
Parameter dim
Must make sure the dimension is SeriesDimensionLoose. Because only those dimensions will have auto-generated dimension names if not have a user-specified name, and other dimensions will get a return of null/undefined.
Because of this reason, should better use getDimensionIndex instead, for examples:
const val = data.getStore().get(data.getDimensionIndex(dim), dataIdx);
Concrete dim name.

method getDimensionIndex

getDimensionIndex: (dim: DimensionLoose) => DimensionIndex;

Get dimension index in data store. Return -1 if not found. Can be used to index value from getRawValue.

method getDimensionInfo

getDimensionInfo: (dim: SeriesDimensionLoose) => SeriesDimensionDefine;

Get type and calculation info of particular dimension
Parameter dim
Dimension can be concrete names like x, y, z, lng, lat, angle, radius Or a ordinal number. For example getDimensionInfo(0) will return 'x' or 'lng' or 'radius'

method getDimensionsOnCoord

getDimensionsOnCoord: () => SeriesDimensionName[];

concrete dimension name list on coord.

method getId

getId: (idx: number) => string;

Never null/undefined. number will be converted to string. Because: In all cases having encountered at present, id is used in making diff comparison, which are usually based on hash map. We can keep the rule that the internal id are always string (treat 2 is the same as '2') to make the related logic simple.

method getIndices

getIndices: () => globalThis.ArrayLike<number>;

method getItemGraphicEl

getItemGraphicEl: (idx: number) => Element;

method getItemLayout

getItemLayout: (idx: number) => any;

Get visual property of single data item

method getLayout

getLayout: (key: string) => any;

Get layout property.

method getMedian

getMedian: (dim: DimensionLoose) => number;

method getName

getName: (idx: number) => string;

Never be null/undefined. number will be converted to string. Because: In most cases, name is used in display, where returning a string is more convenient. In other cases, name is used in query (see indexOfName), where we can keep the rule that name 2 equals to name '2'.

method getRawDataItem

getRawDataItem: (idx: number) => OptionDataItem;

method getRawIndex

getRawIndex: (idx: number) => number;

method getStore

getStore: () => DataStore;
