**TITLE**
[Feature] In a split graph, if showSymbol is set to false, can a point be displayed when both sides of a data item are null?
**BODY**
### What problem does this feature solve?
Our team really likes the effect of setting showSymbol to true, which gives our charts a clean look and good interaction at the same time.
But this has a bad point, that is, if both sides of a data item are null, then this data item will not have any display, such as the following [example](https://echarts.apache.org/ examples/zh/editor.html?c=line-smooth&code=PYBwLglsB2AEC8sDeAoWsAeBBDEDOAXMmurGAJ4gCmRA5AMYCGYVA5sAE7m0A0J6AE2aMiAbVoBZGL1i0AKgFcqM2gHUqAlXIAWClQDEOEFQGVmphdFoBdEgF8-6cjnxFUpMpRqyAbowA2SrT2PLAkYMDA_pAgbvxkRqysVBx0jLh4wegOJHgpEFSEsKLx7h6weNrAAO4m5AC2AEZRRABmAXmO5UJgIsUAHABMAAyh0Ar-_qEAnMMAjGMTU7Bzg7OhcwDMm6MrmyPWXR4U1HT-ENDKR6R49ZFg2kRgHErxdiS2dgDcQA)：

Therefore, I would like to ask if it is possible to display a small dot in the place where the inflection point of the stitching is located for identification, so that users can perceive that there is actually data here:
It's nice to see how the Grafana app handles the problem:

Then I looked through the ECharts documentation and issues list, but couldn't find an easy way to do it. Of course it can be done in some complicated way, but I'm wondering if there is or can be an easy way to do it. If you already have it, please let me know.
### What does the proposed API look like?
Well, not sure what the way I want it to be, maybe we can discuss one, if it doesn't exist yet.
