A method for the graphical display of a plurality of series of numerical data is provided which includes: determining a smallest and a largest numerical value within each series of numerical data; calculating a relative change between said smallest and said largest numerical value within each series of numerical data; determining a largest relative change out of said relative changes; generating a plurality of graphical representations to be displayed on a display means, wherein each graphical representation is representing one series of numerical data out of the plurality of series of numerical data, the numerical data being represented by indicators in the graphical representation; wherein an interval between a minimum position and a maximum position in a first direction of each graphical representation corresponds to an individual range of numerical values between a minimum value and a maximum value; wherein the value of a numerical data is graphically represented by the position of the corresponding indicator in said interval in the first direction, the method further comprising the step of choosing the minimum value and the maximum value individually for each graphical representation on the basis of said largest relative change and at least one of said smallest and said largest value within the corresponding series.
