Title
Does the graphic shape in the chart support custom SVG?
Description
How to customize the start and end icons in datazoom? Tried the configurable items in dataZoom.startHandler.style symbolType and didn’t find what I needed
Solution
Configure symbolType in the primitive style. The shape type of symbol supports passing in built-in types, and can also be set to a custom path string and svg image. The same configuration can be done for any symbol type primitive in VChart.
