According to Wien's Displacement Law, the peak emission wavelength (${\lambda }_{max}$) is inversely proportional to the absolute temperature ($T$). The relationship is expressed as ${\lambda }_{max}\propto \frac{1}{T}$. From the graph, the peak wavelengths follow the order ${\lambda }_{max,2}<{\lambda }_{max,3}<{\lambda }_{max,1}$. Therefore, the temperatures follow the inverse order: $T_2>T_3>T_1$.
