Describe the feature request

For all time graphs, it would be nice to be able to have finer-grain control over how the legend is displayed (e.g. which side it appears, the type, like whether it's like the CPU one or normal ones, hiding it, etc).

It would be useful to have the memory and network charts legends on the left too, maybe even by default, since right now it often happens you don't see anything until a few minutes after it happened because the chart lines are hidden by the legend.

I'll add my request here since it seems more appropriate here than in a separate issue. I'd be nice to have an option to choose to show either the box of info in mem/net, over using the graph. Especially so if using a tiling wm such as I, and you've got a lot of windows open. That way when the window for btm gets shrunk I'd see the number like this
rather than just seeing a graph which isn't all the useful when in small window.

I completely agree this comment. So I make available that the chart can have a left legend at ratatui v0.25(ratatui-org/ratatui#378).

I tested that chart draw a legend on left side. How about it?

I'd say it's definitely more useful, thanks @lyuha!

I read the refactoring commit(77777ef).
Now the TimeChart has an option to configure it's legend position. However, Bottom doesn't have any config option about a legend position.

Is there any plan about this?
Add options like cpu's left_side in config file, add key layout section in config? or have any other?

[ClementTsang]

Yep, was planning on adding this at some point.

Is there anything that I help this work?

[ClementTsang]

If you want you can try to make a PR, but it's mostly figuring out how the config/arg option would look really.
