要将柱状图伸长一点,可以通过调整`grid`组件的属性来实现。具体来说,可以增加`grid.bottom`属性的值,使得图表向上移动,从而留出更多空间放置`yAxis[1]`的数值标签。示例如下:
```javascript
const option = {
tooltip: {
show: true
},
legend: {
show: false,
},
grid: {
top: 5,
bottom: 20, // 增加 bottom 属性的值
right: 0,
},
xAxis: {
show: false,
type: 'value',
},
yAxis: [
{
type: 'category',
inverse: true,
axisLine: {
show: false,
},
axisTick: {
show: false,
},
axisPointer: {
label: {
show: true,
margin: 30,
},
},
data: dataList.map((item) => item.name),
axisLabel: {
margin: 40,
fontSize: 14,
align: 'left',
color: '#31373D',
rich: {
a1: {
color: 'rgba(0, 0, 0, 0)',
backgroundColor: {
image: img1,
},
width: 30,
height: 30,
align: 'center',
borderRadius: 2,
},
a2: {
color: 'rgba(0, 0, 0, 0)',
backgroundColor: {
image: img2,
},
width: 30,
height: 30,
align: 'center',
borderRadius: 2,
},
a3: {
color: 'rgba(0, 0, 0, 0)',
backgroundColor: {
image: img3,
},
width: 30,
height: 30,
align: 'center',
borderRadius: 2,
},
b: {
color: '#000000',
backgroundColor: '#F4F5FC',
width: 30,
height: 30,
align: 'center',
borderRadius: 50,
