Displaying method to display statistical chart on scientific plotting type calculator and a calculator applied the like

Abstract

This invention relates to a method to display a statistical chart on scientific plotting type calculator, which is simulated a three-dimensional coordinates, with an axis X, an axis Y and a simulate axis T, to display several points represented as (x, y, t) on display screen. The way of this invention to display a simulated three-dimensional statistical chart on scientific plotting type calculator space is used several pairs of data as points constituted by series of X value and Y value, according magnitude in sequence of t value orderly to display those points and synchronously connected with line, to form a correlative statistical graph so that user can directly observe an interrelation between value of (x, Y) and t time value from display screen.
