A combined resistivity and hard x-ray diffraction study of superconductivity and charge ordering in $mathrm{Ir_{1-x}Pt_xTe_2}$, as a function of Pt substitution and externally applied hydrostatic pressure, is presented. Experiments are focused on samples near the critical composition $x_csim 0.045$ where competition and switching between charge order and superconductivity is established. We show that charge order as a function of pressure in $mathrm{Ir_{0.95}Pt_{0.05}Te_{2}}$ is preempted - and hence triggered - by a structural transition. Charge ordering appears uniaxially along the short crystallographic (1,0,1) domain axis with a $mathrm{(frac{1}{5},0,frac{1}{5})}$ modulation. Based on these results we draw a charge-order phase diagram and discuss the relation between stripe ordering and superconductivity.
