Echarts Partially introduced error: TypeError: Cannot read property ‘findAxisModel’ of undefined

When introducing dependencies locally in echarts, if there are dependencies that need to be used, an error will be reported if they are not introduced. For example, when using histogram + polar coordinates to display a ring chart, if Ploar is not introduced, an error will be reported in the title. At this time, just introduce this dependency:

require("echarts/lib/component/polar")
