Abstract:
A method for controlling a data display controlling a display of data including at least one attribute, the method comprising:an attribute conversion step of converting at least one attribute of the data into a display attribute by using at least one mapping function; a display step of displaying the data based on the display attribute; and a parameter changing step of changing a parameter of the mapping function, wherein the at least one mapping function includes a shape function and an increase type mapping function in which a derivative of the mapping function becomes a local maximum at the center of the shape function, wherein the function represents an arbitrary shape with at least one attribute to be converted being a variable, and wherein the shape function includes a multi-dimensional function using a plurality of the attributes to be converted as variables, the shape function includes a center parameter representing the center of the shape function, corresponding to each of the variables, a velocity parameter representing a velocity to the center, corresponding to each of the variables, a correlation parameter representing a correlation between the variables, and a rotation parameter representing rotation of a parameter space, and the parameter changing step is a function for calculating one arbitrary value of the display attributes, and includes a step of selecting at least one of the center parameter, the velocity parameter, the correlation parameter, the rotation parameter, and a local maximum value parameter controlling a value of the at least one mapping function when the at least one mapping function is an angular type function which becomes a local maximum at the center of the shape function, the increase type mapping function being obtained from the angular type function by indefinite integration, and using the selected parameter as a parameter set of the at least one mapping function.
