How to break this limit?

问题

This is a limt when using label.new. So has some way for break this limit? I just achieve the follow goal.

The following code can achieve goals but has limits.

label.new(bar_index, high, '1', textcolor=color.red, style=label.style_none)
label.new(bar_index, high, '2\n', textcolor=color.green, style=label.style_none)
label.new(bar_index, high, '3\n\n', textcolor=color.blue, style=label.style_none)
