首先看下代码把
option = {
legend : {},
tooltip : {
trigger : 'axis',
showContent : false
},
dataset : {
source : [
[ 'product', '01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12' ],
[ 'tom', 41.1, 30.4, 65.1, 53.3, 83.8, 150 ],
[ 'jerry', 86.5, 92.1, 85.7, 83.1, 73.4, 55.1 ],
[ 'M', 50, 92.1, 50, 83.1, 73.4, 55.1 ],
[ 'C', 24.1, 67.2, 79.5, 86.4, 65.2, 82.5 ],
[ 'W', 55.2, 67.1, 69.2, 72.4, 53.9, 39.1 ]
]
},
echarts官方的是这样
然后我再下面调用function的时候是这样的
var ar =[['product', '2012', '2013', '2014', '2015', '2016', '2017'],['Matcha Latte', 41.1, 30.4, 65.1, 53.3, 83.8, 98.7],['Milk Tea', 86.5, 92.1, 85.7, 83.1, 73.4, 55.1],['Cheese Cocoa', 24.1, 67.2, 79.5, 86.4, 65.2, 82.5],['Walnut Brownie', 55.2, 67.1, 69.2, 72.4, 53.9, 39.1]];
option.dataset.source = ar;
myChart.setOption(option, true);
这样的话没反应 有没有大神知道是不是 option.dataset.source这个路径不对
还是echarts4 有新的规则了

求助

myChart.setOption({
dataset: {
source: [
['product', '2012', '2013', '2014', '2015', '2016', '2017'],
['Matcha Latte', 41.1, 30.4, 65.1, 53.3, 83.8, 98.7],
['Milk Tea', 86.5, 92.1, 85.7, 83.1, 73.4, 55.1],
['Cheese Cocoa', 24.1, 67.2, 79.5, 86.4, 65.2, 82.5],
['Walnut Brownie', 55.2, 67.1, 69.2, 72.4, 53.9, 39.1]
]
}
});
试一下这个代替你上面的那些内容。我也是刚学这个东西，对他感兴趣。

问题解决了 整体模板里面 套了个function 把这个function去掉就好了~~
