Y轴的值不能写固定,但是data里面有负值的情况下,0坐标点不对齐,就会变得非常难看,怎么能让0坐标点对齐
配置项如下
var colors = ['#5793f3', '#d14a61', '#675bba'];
option = {
color: colors,
tooltip: {
trigger: 'axis'
},
grid: {
right: '20%'
},
toolbox: {
feature: {
dataView: {show: true, readOnly: false},
restore: {show: true},
saveAsImage: {show: true}
}
},
legend: {
data:['蒸发量','降水量','平均温度']
},
xAxis: [
{
type: 'category',
axisTick: {
alignWithLabel: true
},
data: ['1月','2月','3月','4月','5月','6月','7月','8月','9月','10月','11月','12月']
}
],
yAxis: [
{
type: 'value',
name: '蒸发量',
position: 'right',
axisLine: {
lineStyle: {
color: colors[0]
}
},
axisLabel: {
formatter: '{value} ml'
}
},
{
type: 'value',
name: '降水量',
position: 'right',
offset: 80,
axisLine: {
lineStyle: {
color: colors[1]
}
},
axisLabel: {
formatter: '{value} ml'
}
},
{
type: 'value',
name: '温度',
position: 'left',
axisLine: {
lineStyle: {
color: colors[2]
}
},
axisLabel: {
formatter: '{value} °C'
}
}
],
series: [
{
name:'蒸发量',
type:'bar',
data:[2.0, 4.9, 7.0, 23.2, 25.6, 76.7, 135.6, 162.2, 32.6, 20.0, 6.4, 3.3]
},
{

type:'bar',
yAxisIndex: 1,
data:[2.6, 5.9, -9.0, 26.4, 28.7, 70.7, 175.6, 182.2, 48.7, 18.8, 6.0, 2.3]
},
{

}
