In the Highchart Gantt chart if we reduce the navigation handler width too much it will overlap the data when scrolling. Is there a way to set the minimum handler width to eliminate the issue?
You can use the xAxis.minRange
property to limit the minimum width of the range.
xAxis: {
minRange: 1000 * 60 * 60 * 24 * 30 // 1 month
}
