Es ist möglich, in HighCharts auf derselben Linie verschiedenfarbige Datenpunkte zu haben.Highcharts Mehrfache Balkenfarben im X-Bereich
Ich habe es geschafft mehrere Punkte auf der gleichen Linie zu erhalten, indem die Highcharts X-Range example folgende und mit:

tooltip: {
pointFormat: '<span style="color:{point.color}">\u25CF</span> {series.name}: <b>{point.yCategory}</b><br/>'
}
});
H.seriesTypes.xrange = H.extendClass(columnType, {

Demo: JSFiddle Example
ich durch den Zusatz „Farbe ist auch die Farbe der Balken geändert: ' # BF0B23 '", jedoch möchte ich die 3 Balken in" Item 1 "in verschiedenen Farben darstellen. Irgendwelche Ideen, wenn das möglich ist?
Excellent Dank, ich dachte, dass ich die Dokumentation gelesen habe, dass die Farbe in einer Reihe Ebene angewandt wurde, aber das macht durchaus Sinn. – ca8msm
