[v5]what the base type for .line() .interval

[coader]

I have a chart and it whould dynamic change type:
let mark:????
if (type=='line')
mark=chart.line()
else if (type=='interval')
mark=chart.interval()

how to define the mark type in typescript?

[pearmini]

That's a good issue. The base type of mark should be exported. @pepper-nice

And it may change the name from MarkBase to Mark.

tks, it will be useful to encapsulate chart as vue component
