Question

我遵循nativescript-ui-samples-angular https://github.com/NativeScript/nativescript-ui-samples-angular 并且可以在运行应用程序时查看图表。当我在应用程序中使用相同的代码时，IOS和Android上没有显示图表。我不知道怎么了我会错过一些配置吗？谢谢

chart.component.html

<RadCartesianChart tkExampleTitle tkToggleNavButton>
    <CategoricalAxis tkCartesianHorizontalAxis lastLabelVisibility="Hidden" ios:firstLabelVisibility="Hidden"
        ios:plotMode="OnTicks">
    </CategoricalAxis>
    <LinearAxis tkCartesianVerticalAxis></LinearAxis>

    <AreaSeries tkCartesianSeries [items]="categoricalSource" categoryProperty="Country" valueProperty="Amount">
    </AreaSeries>
</RadCartesianChart>

chart.component.ts

import { Component,ElementRef, ViewChildren, QueryList, OnInit } from "@angular/core";
import { ObservableArray } from "tns-core-modules/data/observable-array";
import { DataService } from "./data.service";
import { Country } from "./country";

@Component({
    selector: "ns-charts",
    moduleId: module.id,
    templateUrl: "./chart.component.html",
    styleUrls: ['./chart.component.css']
})
export class ChartComponent implements OnInit {
    private _categoricalSource: ObservableArray<Country>;

    constructor(private _dataService: DataService) { }

    get categoricalSource(): ObservableArray<Country> {
        return this._categoricalSource;
    }

    ngOnInit() {
        this._categoricalSource = new ObservableArray(this._dataService.getCategoricalSource());
        console.log(this._categoricalSource);
    }
}

country.ts

export class Country {
    constructor(public Country?: string, public Amount?: number, public SecondVal?: number, public ThirdVal?: number, public Impact?: number, public Year?: number) {
    }
}

data.service.ts


import { Country } from "./country";
import { Injectable } from '@angular/core';

@Injectable()
export class DataService {

    getCategoricalSource(): Country[] {
        return [
            { Country: "Germany", Amount: 15, SecondVal: 14, ThirdVal: 24, Impact: 0, Year: 0 },
            { Country: "France", Amount: 13, SecondVal: 23, ThirdVal: 25, Impact: 0, Year: 0 },
            { Country: "Bulgaria", Amount: 24, SecondVal: 17, ThirdVal: 23, Impact: 0, Year: 0 },

            { Country: "USA", Amount: 18, SecondVal: 8, ThirdVal: 21, Impact: 0, Year: 0 }
        ];
    }
}

您必须在模块中导入图表模块。ts

import { NativeScriptUIChartModule } from "nativescript-ui-chart/angular";

本机脚本-图表未显示
