A machine-implemented process for determining, scaling, providing, and presenting comparative information in an accurate, scaled, useful, easily recognized, and understandable manner, including: reading the data sets; setting first and second boundaries of a first reference axis using first coordinates of data points of one data set having maximum and minimum values, respectively; setting first and second boundaries of each of the other reference axes by adjusting either the first coordinate of one data point of the selected data set having a maximum value or the first coordinate of one data point of the selected data set having a minimum value, wherein every E-value calculated based on the thus-obtained final first and second boundaries of the each of the other reference axes is substantially equal to an E-value of the first data set; and plotting the data points of the data sets. An electronic device capable of presenting a multiple-axis graph is also disclosed.
