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
