Fill Chart dynamically with variables from Component

i am new to Angular so i think i'm missing something.



i have 3 variables in my component, those variables are being filled after calling .subscribe method on an observable object.



like this



this.interRetard = this.technicienService.getInterRetard(id).subscribe(data => {
this.interRetard = data;
});


the interRetard variable contains a number, i can display its value in the html by doing {{interRetard}} .



the problem is that when i try to display it with console.log() it says :



Subscriber {closed: false, _parent: null, _parents: null, _subscriptions: Array(1), syncErrorValue: null, …}


and i need it to give me the exact value like it is displaying it in the html so i can assign it to the chart like this



public doughnutChartData:number = [this.interRetard ,  5, 10];


Thank you.

    You seem to be using this.interRetard 2 times. Once to hold the subscription returned by the subscribe, and again when you assign data to it inside the subscribe.

    this.interRetard is being assigned twice in your statement. You only need to assign it inside the subscribe callback.
