我正在尝试根据命名地图在我们的CartoDB帐户中可视化私有数据集。命名映射已创建并存在(使用 https://{username}/api/v1/map/named？api_key={api-key} 进行测试)。
config.json是这样的：

}
}
现在在 JavaScript 中，我尝试以这种方式显示它：
var layerSource = {
type: "torque",
options: {
auth_token: "our_token",
user_name: "our_user",
tile_style: css,
named_map: {
name: "deichbreschen_named_map"
}
}
};
cartodb
.createLayer(map, layerSource)
.addTo(map)
.on("done", function(layer) {
// add time slider on change
map.addLayer(layer);
})
.on("error", function(err) {
console.log("some error occurred: " + err);
});
但是我得到一个错误： 从命名映射渲染返回的扭矩层时出错
我做错了什么，有人可以提供一个简单的例子来说明我如何编写扭矩 CSS 来随着时间的推移呈现分类多边形吗？
扭矩.js仍然不支持多边形吗？这可能是原因吗？
想象一下，在我的源图层中，我有一个带有双精度值的字段 h，并使用颜色代码定义了分类间隔：
h <1.00 #XXYYZZ H <2.00 #AABBCC ...
这在扭矩上可能吗？
扭矩不支持(而且很可能永远不会)支持面或线图层，它仅适用于点数据集。
