Abstract: An electronic device capable of graphical data analysis is provided. The device includes a processor capable of manipulating numerical data and a graphical data. An input is provided for issuing instructions to the processor to manipulate the numerical data and graphical data. The device includes a memory device, a software program, and an output. The memory device is for storing graphical data and numerical data. The software program is stored in the memory device and is operable for dynamically linking the numerical data and graphical data, such that when the numerical data is updated the software automatically updates the linked graphical data, and vice versa. The output is operable for displaying graphical data and numerical data.
