switch topics by method

I can pass in themes when I find init, but how to switch themes after initialization

you can see

in http://gallery.echartsjs.com/..

you can click directly to switch topics, but there is no relevant method found in the document

is there any other documentation related to echarts topic configuration?


var chart = echarts.init (dom, 'light'); / / when the table is initialized, it is switched to the light theme

in fact, you can know what to do by looking at the document.
