The paper of Cockburn and Shu [1] explains this. If the solution is $$u_h(x) = u_i + u_{xi} \phi(x), \qquad \phi(x) = \frac{x - x_i}{\Delta x/2}$$ Then the limiter is $$u_{xi} = minmod(u_{xi}, u_i - u_{i-1}, u_{i+1}-u_i)$$ Does your solution representation look as in the first equation above ? Also, the solution with normalised Legendre basis will look ...
