php jpgraph barplot with multiple line label

Question

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?

Answer 1

Ok, I have solved it, it is just some syntax error.

instead of str_replace(' ', '\n', str)

i should use str_replace(' ', "\n", str)
