我有一个Angular 7(Ionic 4)项目,我在那里试用Chart.js,需要能够自定义绘制饼图上的一些标签,因为我已经要求here。
有人告诉我需要使用一个单独的包来完成这个任务,但是我不能使用npm包来导入一个Angular 项目。
我有以下版本:
"chart.js": "^2.8.0",
"chartjs-plugin-datalabels": "^0.6.0",
....
"@angular/*": "^7.2.2",
"typescript": "~3.1.6"
我已经按照建议尝试了here,但是我得到了两个错误。
第一个vscode会产生下列错误:
此外,还添加了此处所述的额外内容。
在其他地方,据说导入如下:import 'chartjs-plugin-datalabels';
但是我随后得到了编译错误:
`[ng] ERROR in node_modules/chartjs-plugin-datalabels/types/index.d.ts(5,16): error TS2665: Invalid module name in augmentation. Module 'chart.js' resolves to an untyped module at 'D:/dev/ionic/chartjstest/node_modules/chart.js/dist/Chart.js', which cannot be augmented.`
我怎么才能让它工作呢?

You can import the directive like this:
You can use Plugins in your
ChartOptions
like this:Another way is to call it in your chart:
You can see it done here.
However, both ways declare it globally. The only way I could figure out not to see them in all charts is to not display them.
This also solves the Problem @NakulSharma has. You can see the plugin options here .
