Patent ID: 8464171

Claim:
A device for the dimensionally variable display of a function chart on a display ( 10 ) of a laboratory apparatus, comprising a processing unit ( 14 ) that accesses data storage means ( 16 , 18 , 20 ) for digital laboratory data to be displayed as a function chart, prepares the digital laboratory data for depiction on the display, and can be manually operated via mechanically actuated keys and/or switching means ( 24 ), wherein the processing unit for performing the dimensional change of the depicted two-dimensional function chart is designed in such a way that a dimensional change in the abscissa toward a target range is performed as a reaction to actuating the first key and/or switch ( 28 , 30 ) and shown on the display in such a way that the target range occupies a predetermined region of the abscissa, and the function chart is displayed along the ordinate in such a way that a predetermined range of ordinates automatically expands the region between a function maximum or a function minimum in the target range, and a reference point in the target range, and wherein the processing unit is designed in such a way that the function chart along the ordinate is displayed during actuation of the first and/or a second key or switch via automatic, continuous adjustment of the predetermined region of the ordinate, wherein continuous adjustment of the predetermined region of the ordinate comprises maintaining the maximum at a maximum display position in the ordinate direction while the minimum is moved to the region of the zero line.
