Feature request: more responsive label for pie charts #4082

[Wenli Zhang <ov...@gmail.com>]

Hi all,

Here's a frequently requested feature on GitHub, a more responsive label
design for pie charts. See
https://github.com/apache/incubator-echarts/issues/4082 for more detail.

In this email, we'd like to discuss about the potential methods to improve
it.

Here are some of my ideas for a start.

1. Restrict labels not to be outside the container
2. For long labels, we can add '\n' at certain position (fixed length? only
labels cannot be put inside the container?)
3. A bold attempt to put labels more far away (may cause labelLine length
altered)

Any more idea?
