我改写了这个方法，将就凑合一下吧
function formatTpl(tpl, paramsList, encode) {
if (!isArray(paramsList)) {
paramsList = [paramsList];
}
var seriesLen = paramsList.length;
if (!seriesLen) {
return '';
}
var $vars = paramsList[0].$vars || [];
for (var i = 0; i < $vars.length; i++) {
var alias = TPL_VAR_ALIAS[i];
tpl = tpl.replace(wrapVar(alias), wrapVar(alias, 0));
}
for (var seriesIdx = 0; seriesIdx < seriesLen; seriesIdx++) {
for (var k = 0; k < $vars.length; k++) {
var val = paramsList[seriesIdx][$vars[k]];
if (zrUtil.isObject(val)) {
if(paramsList[seriesIdx].componentSubType=='pie'){
for( var key in val){
if(val[key]
!=paramsList[seriesIdx].name){
val =val[key]
}
}
}
}
tpl = tpl.replace(
wrapVar(TPL_VAR_ALIAS[k], seriesIdx),
encode ? encodeHTML(val) : val
);
}
}
return tpl;
}
-----------------只有当dataset只有两维数据才有效。如果数据维度多了，这个循环可能就指向的是错误 的数据了
