Constant stroke dash size when zooming MapChart
We can use setting strokeDasharray to make lines on a MapChart dashed. However, zooming in will also make dashes grow in size. This demo shows how we can add adapter which would maintain the same dash length across zooms.
lineSeries.mapLines.template.line.nonScalingStroke = true;lineSeries.mapLines.template.line.strokeDasharray = "5 3";lineSeries.mapLines.template.line.adapter.add("strokeWidth", function(strokeWidth, target){ target.strokeDasharray = (5 / chart.zoomLevel) + " " + (3 / chart.zoomLevel) return strokeWidth;});lineSeries.mapLines.template.line.nonScalingStroke = true;lineSeries.mapLines.template.line.strokeDasharray = "5 3";lineSeries.mapLines.template.line.adapter.add("strokeWidth", function(strokeWidth, target){ target.strokeDasharray = (5 / chart.zoomLevel) + " " + (3 / chart.zoomLevel) return strokeWidth;});
