Patent ID: 8466918

Claim:
A method for generating, by a computer, a font-based sparkline, comprising the steps of: a computer program causing the computer to display the sparkline by locating two or more than two glyphs out of a plurality of predefined glyphs side by side so as to form said sparkline, each of said glyphs out of said plurality of predefined glyphs having a predefined visible portion comprising at least one predefined line having two margins defining the thickness of the lines, wherein in each glyph out of said plurality of predefined glyphs the predefined line comprised in said visible portion of said glyph has a first terminating portion and a second terminating portion, wherein the end of at least one out of said first terminating portion or said second terminating portion is formed by a shaping element, such that the line and the shaping element form an integral part of said predefined visible portion of said glyph, wherein the shaping element has a rounded contour formed by a circle or part of circle having a radius which corresponds or approximately corresponds to half of the thickness of the line and wherein said contour is in alignment with the margins of the terminating portion of the line, wherein each glyph out of said plurality of predefined glyphs has a predefined left border and right border, which borders define the transition from one glyph to an adjoining glyph, a predefined bounding area having a left boundary and a right boundary, which boundaries are the left and right limits of the predefined visible portion of the glyph, as well as a predefined left side bearing which is the space between the left border of the glyph and the left boundary of the bounding area and a predefined right side bearing which is the space between the right border of the glyph and the right boundary of the bounding area, wherein the predefined left border and right border of all the glyphs out of said plurality of predefined glyphs are parallel to each other, wherein one or both of the predefined left side bearing and the predefined right side bearing of the glyphs are negative, wherein the computer program causes the computer to generate the sparkline by assembling at least a first and a second glyph out of said plurality of predefined glyphs side by side with their respective left or right parallel borders adjoining, and wherein said one or both of said negative left and right side bearing is predefined in such a way that a shaping element forming a first or second terminating portion of a predefined first line comprised in a predefined visible portion of the first glyph overlaps with a first or second terminating portion of a predefined second line comprised in a predefined visible portions of the second glyph to obtain a smooth transition between said predefined first and second lines.
