A method creates a data grid component in a GUI. The data grid includes data cells, header cells, corner cells, and may further include footer cells. The data grid component may have headers or footers that contain a scale and/or a ruler that relates to graphs shown in a row or column associated with the header or footer. The scale and/or ruler may be horizontal or vertical.
The GUI component may allow for multilevel navigation. One level allows for navigating from component to component in the GUI, including the data grid and any other components. Another level allows for navigating within a component, including in the data grid. Available user navigation inputs include level change commands, for example tied to specific keys.
