Hello, I am working on a URL shortener. I am using Ng2GoogleChartModule in
my AnalyticsComponent.
I have a table where I have multiple short URL. When I choose the first URL
and see the analytics of the first URL
first time when my component is initialized it displays the data in the geo
chart but when I go back to my data table and
redirect to another short URL. I am getting this error *ERROR Error:
Uncaught (in promise): Error: Row 0 has 0 columns,*
but must have 2* (*I am also attaching the screenshot of the error which I
am getting in my browser console*).*
Here is my component.ts file
import { Component, OnInit } from '@angular/core';
import { ActivatedRoute, Router } from '@angular/router';
import { UsersLinksService } from '../../Services/users-links.service';
@Component({
selector: 'app-analytics',
templateUrl: './analytics.component.html',
styleUrls: ['./analytics.component.css'],
})
export class AnalyticsComponent implements OnInit {
constructor(private route: ActivatedRoute, private usersLinks:
UsersLinksService, private router: Router) {}
public geoChartData = { chartType: 'GeoChart', dataTable: [['Country',
'Click'], []] };
ngOnInit() {
const url = this.route.snapshot.paramMap.get('shortUrl');
this.usersLinks.linkCountry(url).subscribe((country: any) => {
if (country.length === 0) {
return false;
} else {
for (let index = 0; index < country.length; index++) {
this.geoChartData.dataTable[1].push(country[index]._id.TotalCountry.
countryName, country[index].clicks);
}
}
}, error => {this.errorMsg = error; });
}
}
This is my components.html
<div style="display: block">
<google-chart [data]="geoChartData"></google-chart>
</div>
