@mzy2240 http://www.echartsjs.com/option.html#series-lines.label.position label.position set middle,

mzy2240 commented 5 years ago

Wow thanks man. However, I already have other text labels in the middle of the lines, so this may not work for me. Any other ideas? Thanks!

cuijian-dexter commented 5 years ago

@mzy2240 What effect do you want?I think you can add arrows through label.rich.

mzy2240 commented 5 years ago

For example, I want the arrow in the middle of the lines, while the labels will be above the lines.
