我正在使用fl_chart库来绘制折线图。到目前为止我所做的是，
return LineChartData(
gridData: FlGridData(
show: false,
drawVerticalLine: false,
getDrawingHorizontalLine: (value) {
return FlLine(
strokeWidth: 0,
);
},
getDrawingVerticalLine: (value) {
return FlLine(
strokeWidth: 0,
);
},
),
titlesData: FlTitlesData(
show: true,
rightTitles: SideTitles(
showTitles: true,
interval: 3,
rotateAngle: 330,
getTextStyles: (context, value) => const TextStyle(
color: Color(0xffffffff),
fontWeight: FontWeight.w400,
fontSize: 10,
),
getTitles: (value) {
return yAxis[value.toInt()];
},
reservedSize: 30,
margin: 5,
),
topTitles: SideTitles(showTitles: false),
bottomTitles: SideTitles(
showTitles: true,
reservedSize: 18,
rotateAngle: 320,
interval: 3,
getTextStyles: (context, value) => const TextStyle(
color: Color(0xffffffff),
fontWeight: FontWeight.w400,
fontSize: 10),
getTitles: (value) {
print("xAxis values $value - ${xAxis[value.toInt()]}");
return xAxis[value.toInt()];
},
margin: 8,
),
leftTitles: SideTitles(showTitles: false),
),
borderData: FlBorderData(
show: true,
border: Border.all(color: const Color(0xFFFFFFFF), width: 1)),
minX: 0,
minY: 0,

从上面的响应整数值是时间戳，我希望以“yy-MMM”格式显示 x 轴。
我在用响应绘制 FlSpots 时遇到问题。我尝试使用正确绘制的硬代码值。现在我想将响应值设置为 FlSpot。flSpot 仅接受双精度值。
