chart-geo with angular about chartjs-chart-geo HOT 7 CLOSED

re angular: this is just a plugin that extends chart.js so you can use tools like ng2-chartjs which embed chart.js in Angular.

Based on that I created the Choropleth map from the example in Angular in https://codesandbox.io/s/angular-chartjs-geo-npzhk?file=/src/app/app.component.ts

from chartjs-chart-geo.

@sgratzl thanks a lot! I will use your example!

Hi @sgratzl sorry for reopen this issue!

So I try to use your example and I solution my problem with this new simple example. If someone would like know how create map country with angular just use it.

Hi @sgratzl
I've tried to reproduce your example in my project but I'm getting error which says
"choropleth" is not a chart type.

Is there a specific place where I should register choropleth as new chart type or I'm doing something wrong?

my chartjs version is 2.9.3 and chartjs-chart-geo version is 2.1.0

from chartjs-chart-geo.

Well, I simply forgot to add following import
import "chartjs-chart-geo";

Sorry for bothering you :)
