// Seu código ECharts aqui
const gaugeData = [{

];
let myChart = echarts.init(document.getElementById('gaugeChart'));
const option = {
series: [{
type: 'gauge',
clockwise: false,
startAngle: 140,
endAngle: -90,
min: 0,
max: 100,
pointer: {
show: true
},
axisLabel: {
color: 'red'
},
progress: {
show: true,
overlap: false,
roundCap: true,
clip: false
},
data: gaugeData
}]
};
myChart.setOption(option);
</script>

我尝试将
itemStyle: {backgroundColor: 'transparent'}
设置在 progress: {...}
内,但不起作用。如何在仪表echarts中调整它?
从文档(https://echarts.apache.org/en/option.html#xAxis.axisLine.lineStyle.opacity)中,这将使用
axisLine.lineStyle
选项进行配置:
const option = {
series: [{
type: 'gauge',
clockwise: false,
startAngle: 140,
endAngle: -90,
min: 0,
max: 100,
pointer: {
show: true
},
axisLabel: {
color: 'red'
},
axisLine: {
lineStyle: {
opacity: 0, //See here
}
},
progress: {
show: true,
overlap: false,
roundCap: true,
clip: false
},
data: gaugeData
}]
};
如果您愿意,您还可以选择调整宽度,您可以从链接的文档中查看其他选项。
