Gestapeltes Highcharts-Säulendiagramm

Highcharts Säulendiagramm

Das folgende Beispiel zeigt ein gestapeltes gruppiertes Balkendiagramm.

Wir haben die grundlegende Konfigurationssyntax von Highcharts bereits in den vorherigen Kapiteln kennengelernt. Sehen wir uns nun andere Konfigurationen an. Fügen Sie das Attribut series in drilldown hinzu:

Konfiguration

drilldown: Drilldown

drilldown wird verwendet, um einen Drilldown in die Daten durchzuführen und die konkreten Daten darin zu untersuchen.

drilldown: {
   series: drilldownSeries
}
