我想在我的dc.js图表上添加标记集群，并陷入此错误。个别代码正在运行，但将它与饼图，条形图和地图，标记不显示。未捕获TypeError：dc.leafletMarkerChart不是函数

和错误是：
Uncaught TypeError: dc.leafletMarkerChart is not a function
at drawMarkerSelect (bubble.html:118)

'dc.leafletMarkerChart'是dc.js这就是[直流插件]（https://github.com/Intellipharm/dc-addons#leafletjs）库的一部分的延伸部，但我没有看到包含该脚本。 （另一个选项，大致相同，是[dc.leaflet.js]（https://github.com/dc-js/dc.leaflet.js））。 – Gordon
错误解决了我将小册子的代码放入图表中，因此出现此错误 –
