我必须绘制30天数据的融合图表。但由于数据点过多，滚动条即将出现。所以我只想绘制每个第n个标签。为了减少我的x轴尺寸。
融合图表代码在这里：
var ecuChart = new FusionCharts({
//type: 'mscolumn3d',
type: 'scrollline2d',
//type: 'msarea',
renderAt: 'ecuGraphBody',
width: "265",
height: "100%",
dataFormat: "json",
dataSource: {
"chart": {
"subcaption": "Graph",
"xAxisname": "day",
"yAxisName": " $/Hour",

"showLegend": "1",
"numberprefix": "$",
"legendPosition": "bottom",

//"palettecolors": "#f8bd19,#008ee4,#33bdda,#e44a00,#6baa01,#583e78",

},
"categories": [
