Ok, I have solved it, it is just some syntax error.
instead of str_replace(' ', '\n', str)
i should use str_replace(' ', "\n", str)
문제
I want to have multiple line label for my barplot.
I have been using str_replace()
to replace all the whitespace into \r\n or \n
but none of it works. The label did not break into multiple lines.
Did anyone know how to make it right?
