背景：

以柱状图（来自Echarts 插件）为例，如果X轴data数据过长，影响图表体验，为此需要省略部分内容

superset-frontend\plugins\plugin-chart-echarts\src\Timeseries\transformProps.ts

import {
  getBaselineSeriesForStream,
  getPadding,
  getTooltipTimeFormatter,
  getXAxisFormatter,
  getXAxisEllipsisFormatter,
  transformEventAnnotation,
  transformFormulaAnnotation,
  transformIntervalAnnotation,
  transformSeries,
  transformTimeseriesAnnotation,
} from './transformers';

let xAxis: any = {
    type: xAxisType,
    name: xAxisTitle,
    nameGap: convertInteger(xAxisTitleMargin),
    nameLocation: 'middle',
    axisLabel: {
      hideOverlap: true,
      formatter: xAxisFormatter,
      rotate: xAxisLabelRotation
