I want draw a pie like this, and I want to store data in dataset:
option = {
dataset: {
dimensions: ['a', 'b'],
source: { a: 85, b: 79 }
},
series: [
{
name: 'template',
type: 'pie',
// get data from dataset
}
]
};
source is an object, so I can just reset the dataset when source was changed and dont need to do likeoption.series[0].data[0].value = ... for every value.
I was try to set encode.value = ['a', 'b'] or some other settings but it was not work. How can I do for this?
The source format of your dataset should be one of these 3 formats :
source: [
{name: 'a', value: 85},
{name: 'b', value: 79},
]
source: [
['name', 'value'],
['a', 85],
['b',79]
]
source: {
'name': ['a', 'b'],
'value': [85, 79],
}
For example :
var myChart = echarts.init(document.getElementById('main'));
option = {
dataset: {
source: [
{name: 'a', value: 85},
{name: 'b', value: 79},
]
},
series: [
{
name: 'template',
type: 'pie',
}
]
};
myChart .setOption(option)<html>
