This is my typescript code: public barChartData: ChartConfiguration<'bar'>['data'] = { labels: [ '2006', '2007', '2008', '2009', '2010', '2011', '2012' ], datasets: [ { data: [ 65, 59, 80, 81, 56, 55, 40 ], label: 'Series A' }, { data: [ 65, 59, 80, 81, 56, 55, 40 ], label: 'Series B' }, { data: [ 28, 48, 40, 19, 86, 27, 90 ], label: 'Series C' } ] }; HTML code: <canvas baseChart [data]="barChartData" [options]="barChartOptions" [legend]="barChartLegend" [type]="'bar'"> </canvas> so into UI i set radio group, day, month, yearly. When i click the radio i call another method who return the datasets: setBar() { this.barChartData.datasets = [] this.barChartData.labels = [] if(this.statisticsRes.length > 0) { let labelsSet: string[] = [] if(this.optionTimer == environment.statisticTime.daily){ labelsSet = this.getLast24Hours(); } if(this.optionTimer == environment.statisticTime.monthly){ labelsSet = this.getLast30Days(); } if(this.optionTimer == environment.statisticTime.annual) { labelsSet = this.getLast12Months(); } this.barChartData.labels = labelsSet // BAR this.barChartData.datasets = [ { data: this.statisticsRes.map((o) => o.travelcounter).reverse(), label: 'Travelcounter' }, { data: this.statisticsRes.map((o) => o.odometer).reverse(), label: 'Odometer [m]' }, { data: this.statisticsRes.map((o) => o.countoutofservice).reverse(), label: 'Number of blocking errors' } ] // need here to update the charts } } i need to update the data, but there is no: this.barChartData.update() or similar. How i can do? Continue reading...
