1. Field of the Invention
The present invention relates to a display apparatus and a computer readable medium.
2. Description of Related Art
Conventionally, a display apparatus for displaying plotted points or approximate graphs has been capable of splitting a display area into two areas, so that plotted points/approximate graphs in different coordinate systems such as an XY coordinate system and an XZ coordinate system can be displayed in each area respectively (e.g., refer to the Japanese Patent Application Laid-Open Publication No. 2003-281102). According to such a display apparatus, it becomes possible to analyze distribution of the plotted points of a three dimensional space simultaneously in a plurality of planes of coordinates and therefore to increase learning effect of a user.
However, by the display apparatus of the above-mentioned patent document, distribution of the plotted points in the three dimensional space and events in the real life cannot be correlated and therefore learning effect of the user is low.
