I have a problem. I have a list of data that I output grouped. Now I want
to output the values e.g. erzeugenGes to a barchart. Chart modules itself
works. Fail only at the grouped data for evaluation. Enclosed my code and
list
1,2,3,4,5,6,7,8,9,10,11,12 are the Month for the ChartLabels
1: [{…}] 2: [{…}] 3: [{…}] 4: [{…}] 5: [{…}] 6: [{…}] 7: [{…}] 8: [{…}] 9:
Array(1) 0: {jahr: 2020, monat: 9, erzeugungGes: 901.04, verbrauchGes:

getData() { this.ds.getAuswertungJahr().subscribe(res => { this.daten =
res; this.data = this.daten.reduce((r, a) => { console.log("a", a);
console.log('r', r); r[a.monat] = [...r[a.monat] || [], a]; return r; },
{}); console.log("group", this.data); this.barChartData[0].data = []; for
(let i = 0; i < this.data.lenght; i++) {
this.barChartData[0].data.push(this.data[i]); } })
