Subject: Legend containing maths symbol and values of variables
In-Reply-To: <971536df0903232124u3e304ce0gb648217052cee8c@mail.gmail.com>
I tried sprintf and paste, which solves one of my problem i.e.
replacing the variable name by its value. However, >= is not renderend
correctly as the inequality symbol.
