  Four-dimensional imaging of charge migration is crucial to understand several
ubiquitous processes in nature. Present work focuses on imaging of charge
migration in an oriented epoxypropane -- a chiral molecule. A linearly
polarised pulse at 45$^{\circ}$ in the $yz$-plane is used to induce the charge
migration, which is imaged by time-resolved x-ray diffraction. It is found that
the elastic as well as inelastic contributions to the total time-resolved
diffraction signals are significantly different for both enantiomers.
Furthermore, time-dependent inelastic signal resembles closely to the
time-derivative of the Fourier transformed electron density, which establishes
a connection between time-resolved x-ray diffraction and electronic continuity
equation.
