A method for presentation of image sequence data is disclosed. The intensity of the image sequence data is used to derive the navigation guide. Each representative data may correspond to an average pixel value, a median pixel value, a minimum value, or a maximum value of the sub-image or said one or more images. Each representative data may also comprise a term proportional to a mathematical product of adjusted color values. The series of representative data can be plotted along with highlighting an area between a curve corresponding to the series of representative data and a coordinate axis by filling the area with a highlight color. Each representative data may comprise a minimum value and a maximum value associated with the sub-image, or one or more images.
