NG2-Charts Can't bind to 'datasets' since it isn't a known property of 'canvas'

Try importing ChartsModule in your app.module.ts like this-

import { ChartsModule } from 'ng2-charts/ng2-charts';

imports: [
   .....
   ChartsModule
   .....
]

I had the very same problem. I found on github that you just have to insert the ChartsModule in the submodule as well. First you add in app.module.ts and the, in my case, reports.module.ts.

I'm working with ng2-charts + Angular 7 + Ionic 4, and I spent several hours searching for a solution. And this finally worked to me (after following the initial steps, of course, like installing ng2-charts and charts.js). Just import ChartsModule on the following files:

app.module.ts

import { ChartsModule } from 'ng2-charts';
...
imports: [ChartsModule]

yourPage.module.ts

import { ChartsModule } from 'ng2-charts';
@NgModule({
  imports: [
    IonicModule,
    CommonModule,
    FormsModule,
    RouterModule.forChild([{ path: '', component: YourPagePage }]),
    **ChartsModule**
  ]
})

I was trying to import it also in yourPage.page.ts, but the solution was to import it in yourPage.module.ts!

Try it out.
