possible that the trigger event may fall between two sampling points to compensate for any trigger event that falls between two sampling points an interpolated data point between the triggering event measurement and a previous sampled measurement may be generated typically the interpolation may be linear but any interpolation method may be used a time t represented by each pixel on the display device may then be computed using the equation t t c t 0 p where t c is a total sampling acquisition time and t 0 is a time offset between the trigger event location and the first point sampled after the trigger event and p is the number of pixels on an x axis of the display t may be a floating point number since t c t 0 is not guaranteed to be a multiple of p the number g of points that need to share a pixel can be obtained using the equation gi round twi where i 1 to n where n is the display width in pixels and where twi is the end time of wi and is calculated as twi t i where i 1 to n amplitude of waveform data at an interpolated time of the trigger event location may be added in the first set w 1 that.
