  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 $x_c\sim
0.045$ 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.
