How to make bottom line dashed?

Question

I have SfCartesianChart and I want to make a bottom line dashed. How to make it?

This is my code:

SfCartesianChart(
  plotAreaBorderWidth: 0,
  plotAreaBorderColor: Colors.white24,
  primaryXAxis: DateTimeAxis(
    majorGridLines: const MajorGridLines(
    width: 0.5,
    color: Colors.transparent,
    ),
  ),
  primaryYAxis: NumericAxis(
    majorGridLines: const MajorGridLines(width: 1, color: Colors.white24, dashArray: <double>[5, 5]),
      minimum: 0,
      maximum: 100
    ),
)

Answer 1

Have you tried playing with the dashArray property on the AxisLine? I.e.:

primaryXAxis: DateTimeAxis(
  majorGridLines: const MajorGridLines(
    width: 0.5,
    color: Colors.transparent,
    ),
  axisLine: AxisLine(
    color: Colors.red, 
    dashArray: <double>[2.0, 1.0],
  ),
),
