How to plot stress contour if nodal values are known (FEM)?

Hello all, I am solving a FEM Problem and I want to plot stress contours using given information. I have a nodal coordinates X, a 1733*2 matrix. A quadrilateral elements nodal connectivity matrix T (Size 1651*4) and a Stress (/sigma_x) matrix, which basically store the values of stress at nodes (a 1651*4 matrix). How can I plot stress contours. Thanks in advance.
