Patent ID: 8284199

Claim:
A graph plotting device comprising: a display area setting section which sets a matrix display area for displaying m×n elements arranged in matrix form wherein m and n are respectively two or more natural numbers and a graph display area for displaying a graph image in an identical display screen; a statistic display processing section which computes m×n statistics between m variates belonging to a first data group and n variates belonging to a second data group and which displays the statistics as matrix elements arranged in n rows and m columns in the matrix display area; a matrix element specification section for specifying any one of the matrix elements displayed in the matrix display area on the display screen; and a graph display processing section which forms a graph image representing a relation between two variates, one of which belongs to the first data group and the other of which belongs to the second data group, corresponding to one matrix element specified by the matrix element specification section, and which displays the graph image in the graph display area on the display screen, wherein the display area setting section sets a first variate name display area which displays names of m variates belonging to the first data group so as to be arranged in row direction corresponding to each column in the matrix display area, and a second variate name display area which displays names of n variates belonging to the second data group so as to be arranged in column direction corresponding to each row in the matrix display area, and wherein the graph plotting device further comprising a variate name display processing section which displays the names of m variates and the names of n variates in the first and second variate name display areas, respectively; a variate name specification section which specifies any one of the names of m variates or the names of n variates; and an arrangement order processing section which rearranges statistics displayed in the matrix display area by each row so that when one of the names of m variates is specified by the variate name specification section, n statistics lined in column direction with respect to the variate whose name is specified are arranged in order of absolute values, while rearranging statistics displayed in the matrix display area by each column so that when one of the names of n variates is specified by the variate name specification section, m statistics lined in row direction with respect to the variate whose name is specified are arranged in order of absolute values.
