HI @rgomesf , can you post a shot of the example you request.

[rgomesf]

Hi @pissang . Sure. Here you go

Be able to format the lines as arrow would also be a nice feature.

This would be a useful feature. Is there any timeline for when this will be available?

Just wanted to throw this would also be valuable for me. I have a use case representing a taxonomy as a tree and it would be useful to add labels to the edges between parents and children to distinguish different types

I found a workaround! :) I hope it is good enough for you all.

I made the relationships to be nodes and I set the symbol of those nodes to "none".

Here is my chartOption data: { "name": "somenodelabel", "children": [ { "name": "somelinelabel", "symbol": "none", "collapsed": false, "children": [ { "name": "somenodelabel", "collapsed": false, "children": [] }, { "name": "somenodelabel", "collapsed": false, "children": [] } ] } ] }

Regarding the arrow at the end of the line, the only workaround I can think of is to create your own node symbol (property "symbol", png file is supported), you could therefore create for example a circle with a preceding arrow and if angle is a problem there is also a parameter for that ("symbolRotate").
