将angular 2数据绑定到predix组件

Question

我正在尝试开发一个在angular 2中使用predix组件绘制图形的页面。目前，我正在尝试一个静态的json数据来显示在图表中。但是我不能绑定数据，因此图形不会显示在页面中。在控制台中，它们也不是错误的。当我将chartData json值直接提供给px-vis-timeseries标记时，它将显示图形。因此，将数据绑定到predix组件是一个问题。我对angular 2和predix都是新手。所以我不知道如何绑定this.Can，有人能帮我一下吗？@珍妮，你有什么想法吗？我看到你也有一个类似的帖子，如果你有答案，请提前帮助我，谢谢…

app.component.ts文件

@Component({
  selector: 'my-app',
  template: `
    <div>
        <h2 id="title_tag" >Timeseries - Chart</h2>
        <px-vis-timeseries
          prevent-resize
          width = "1200"
          height = "800"
          include-all-series
          render-to-canvas
          selection-type= "xy"
          chart-data='{{chartData}}'
          series-config='{{seriesConfig}}'
          x-axis-config='{"title":"Date"}'
          y-axis-config='{"title":"Single","titleTruncation":false,"unit":"F","axis1":{"title":"Temperature","titleTruncation":false,"unit":"C"}}'
          disable-navigator>
        </px-vis-timeseries>
    </div>
  `

})

export class AppComponent{
    var chartData = '[{"x":1397102460000,"y0":11.4403,"y1":96.5,"y2":0.56,"y3":0.56},{"x":1397139660000,"y0":13.1913,"y1":96.5,"y2":0.4,"y3":0.4},{"x":1397177400000,"y0":12.8485,"y1":96.5,"y2":0.43,"y3":0.43},{"x":1397228040000,"y0":10.975,"y1":96.5,"y2":0.33,"y3":0.33},{"x":1397248260000,"y0":12.9377,"y1":96.5,"y2":0.47,"y3":0.47},{"x":1397291280000,"y0":13.3795,"y1":96.5,"y2":0.41,"y3":0.41},{"x":1397522940000,"y0":16.4446,"y1":96.5,"y2":0.32,"y3":0.32},{"x":1397542800000,"y0":12.2771,"y1":96.5,"y2":0.35,"y3":0.35},{"x":1397640960000,"y0":13.0709,"y1":96.5,"y2":0.34,"y3":0.34},{"x":1397663100000,"y1":88.8,"y2":0.28,"y3":0.28},{"x":1397700000000,"y0":12.6198,"y1":95.2,"y2":0.49,"y3":0.49},{"x":1397753040000,"y0":11.0486,"y1":96.5,"y2":0.35,"y3":0.35},{"x":1397772540000,"y0":14.6892,"y1":96.5,"y2":0.21,"y3":0.21},{"x":1397794860000,"y0":14.3738,"y1":96.5,"y2":0.42,"y3":0.42},{"x":1397813580000,"y0":10.4259,"y1":76.5,"y2":0.58,"y3":0.58},{"x":1397890680000,"y0":13.4261,"y1":96.5,"y2":0.37,"y3":0.37},{"x":1397932020000,"y0":13.0062,"y1":96.5,"y2":0.27,"y3":0.27},{"x":1397973480000,"y0":14.475,"y1":96.5,"y2":0.35,"y3":0.35}]';

Answer 1

这是因为ng-reflect属性与angular 2绑定一起，这将不会成功绑定，为了移除ng-reflect绑定数据，如下所示，

Attr.chardata=‘chartData’
