Angular 6 Ngx-charts, xAxis date sorting is wrong

问题

I need to sort x-axis ticks of the chart. I tried to use [xAxisTicks], but it didn't work. I couldn't find any example related with xAxisTicks. I tried to assign a variable inside of it like:

values = ["2012","2013","2014","2015","2016"];

Another interesting thing is, My series is already sorted but it still shows unsorted.

Chart object (series)

See chart's x-Axis

Unless you're using a time series (see https://github.com/swimlane/ngx-charts/issues/434 ), the series 'names' are just strings and don't appear to get sorted when the series don't contain the same sets of 'names'. You can, however, adjust the data to fill in the 'missing' series entries,

export var multi = [
  {
    "name": "memzuc",
    "series": [
      {
        "name": "201801",  // Added
        "value": 0
      },
      {
        "name": "201802",  // Added
        "value": 0
      },
      {
        "name": "201803",
        "value": 350855
      },
      {
        "name": "201804",
        "value": 351673
      },
      {
        "name": "201805",
        "value": 368720
      },
      {
        "name": "201806",
        "value": 366941
      },
      {
        "name": "201807",
        "value": 387829
      },
    ]
  },

  {
    "name": "cwb",
    "series": [
      {
        "name": "201801",
        "value": 342300
      },
      {
        "name": "201802",
        "value": 337298
      },
      {
        "name": "201803",
        "value": 350855
      },
      {
        "name": "201804",
        "value": 359973
      },
      {
        "name": "201805",
        "value": 2179919
      },
      {
        "name": "201806",  // Added
        "value": 0
      },
      {
        "name": "201807",  // Added
        "value": 0
      }
    ]
  }
];
