How to invalidate labels on line and column serieses in amcharts5

[Ashishvkale]

Below is the amchart4 code where line and columnseries labels were invalidated and updated to new data

this.lineSeries?.invalidateLabels()
for (const series of this.columnSeriesArray) series.invalidateLabels()

How can I achieve the same functionality in amchart5 ??

I wanted to truncate my label on my custom variable changes

label.adapters.add("oversizedBehavior", () => {
                if (this.truncateTitles) return "truncate"
                return "none"
            })
