A new method for determining an unknown structure by analizing powder diffraction pattern has been developed especially for the high pressure X-ray diffraction. The method is an extension of 'graphical method' for two dimensions (down to monoclinic structure). The method has been used successfully for Te(II), iodine, Cs(IV) and some sodium halides.
