Abstract: The present invention relates to a method for generating a font-based sparkline, the sparkline being composed of two or more than two glyphs, said glyphs comprising one or more lines or consisting of one or more lines, which lines have two margins defining the thickness of the lines, the method comprising the step of providing at least one shaping element having a contour which at least in part is rounded and locating said shaping element at a position at which neighboring lines of two adjoining glyphs terminate, wherein said shaping element is located so that at least a portion of said contour is in alignment or in approximate alignment with at least one of the margins of one or both of said neighboring lines.
