前端：
var _DataSet = DataSet,
DataView = _DataSet.DataView;
前端获取列表
var temp_data = ‘{{ ret_char_data_root|safe }}‘;
console.log(data,typeof(data));
这时temp_data 是个字符串
var data =JSON.parse(temp_data); 转成json对象
console.log(data,typeof(data));
此时已经是object了。不能直接使用
JSON.parse(‘{{ ret_char_data_root|safe }}‘)。要中转一下。
var dv1 = new DataView();
dv1.source(data).transform({
type: ‘percent‘,
field: ‘money‘,
dimension: ‘type‘,
as: ‘percent‘
});
var chart1 = new G2.Chart({
container: ‘mountNode1‘,
forceFit: true,
height: window.innerHeight
});
chart1.source(dv1, {
percent: {
formatter: function formatter(val) {
val = val * 100 + ‘%‘;
return val;
}
}
});
chart1.coord(‘theta‘);
chart1.tooltip({
showTitle: false,
itemTpl: ‘<li><span style="background-color:{color};" class="g2-tooltip-marker"></span>{name}: {value}</li>‘
