Steps to Reproduce

The link is reproduced

Current Behavior

1. Line chart
2. A large amount of data, tens of thousands, cannot be sampled
3. Can't showSymbol, it will be very stuck
4. If a point is empty before and after, then this point will not be drawn

Expected Behavior

1. Hope this point can be drawn

Environment

- OS: windows
-Browser: edge
- Framework: vue

Any additional comments?

No response

Do you want showSymbol as true or false ? Of course, when false, no points are shown. There is no option for "lines without points" mixed with single points. One workaround is to identify those singular points and create a scatter series to show them separately.

1. If a point is empty before and after, then this point will not be drawn (=translation)

not true. In your example set showSymbol: true and the point for Wednesday will display

if i set showSymbol=true， my page will be very laggy。
i found a solution here： #18815
but it cannot work for me, because my xAxis type is time 😢

Good reference to #18815 . PR has been updated and works with type:'time'.
Demo Code .
So what I said - "There is no option for "lines without points" mixed with single points." - no longer applies, which is good news.
🤞 for PR to be approved (soon). Praise to @linghaoSu for pulling that off 🏆

You are right, modifiy directly will cause breaking change, so I add a new option showDisconnectSymbol , accepting 'auto' | true , default is 'auto' .

• 'auto' will follow the showSymbol behavior.
• true will show the disconnect symbol although showSymbol is false
