How to display point label in line chart?

[shivduttp]

I am trying to use this plugin for my line charts, but the tags are not being inserted after each element like in the example on chartist shows. (https://gionkunz.github.io/chartist-js/plugins.html#point-label-plugin). I have included the plugin JS file in project, also modified angular-cli.json to include JS file, modified tsconfig.app.json & tsconfig.spec.json to set allowJs as true but still no luck. Not sure if i am missing anything. - tsconfig.app.json

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "module": "es2015",
    "baseUrl": "",
    "allowJs":true,
    "types": []
  },
  "exclude": [
    "test.ts",
    "**/*.spec.ts"
  ]
}

tsconfig.spec.json

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/spec",
    "module": "commonjs",
    "target": "es5",
    "baseUrl": "",  
    "allowJs":true,
    "types": [
      "jasmine",
      "node"
    ]
  },
  "files": [
    "test.ts"
  ],
  "include": [
    "**/*.spec.ts",
    "**/*.d.ts"
  ]
}

angular-cli.json

"scripts": [
          "../node_modules/jquery/dist/jquery.js",
          "../node_modules/bootstrap/dist/js/bootstrap.js",

                    this.startAnimationForLineChart(dailySalesChart);
