echartsInstance.setOption更新graphic报错

[ybbdaidai]

One-line summary [问题简述]

barChart中监听legendselectchanged事件并用echartsInstance.setOption更新graphic时报错。错误信息是Uncaught TypeError: Cannot set property '__alive' of undefined。

• 调试后发现：更新的option中只有graphic，如果换成title就不会出错。
• 感觉和下面的逻辑相关，如果可以，我想知道下graphic与其他 type 的不同，为什么要额外判断?

zrUtil.each(option, function(o, mainType) {
    mainType !== 'graphic' && (this.__lastOnlyGraphic = false);
}, this);

/* -------------------------------------------------------------------------------------- */

if (this.__lastOnlyGraphic) {
    each(this._componentsViews, function(componentView) {
        var componentModel = componentView.__model;
        if (componentModel && componentModel.mainType === 'graphic') {
            componentView.render(componentModel, ecModel, this._api, payload);
            updateZ(componentModel, componentView);
        }
    }, this);
    this.__lastOnlyGraphic = false;
} else {
    updateMethods.update.call(this, payload);
}
