Version: 3.2.0
One of these errors are shown when defining multiple visual maps as visualMap:[..]

I've reproduced this on this example: http://echarts.baidu.com/demo.html#map-china-dataRange
when using multiple map series + line series (visual-map-error.js attached inside
visual-map-issue.zip)

I'm defining multiple visual maps so I can style them differenlty:

However, If I add the line series, the error occurs.
It can be fixed by defining one visual map only (visual-map-working.js attached inside
visual-map-issue.zip)

However, the line gets also styled as per visualMap settings:

In 3.1.x, it was possible to define visual maps for specific series where undefined series worked as when visual map is not supported (can style them)
