The present invention aims to delete and restore a chart which is displayed in units of a row or column, to thereby edit the chart. Display means (2) of an electric device (1) displays data which are stored in a chart data part, in the form of a chart. When deleting of a column or row of the chart using coordinates inputting means (3) is instructed, the column or row is deleted, the remaining columns or rows are moved close to each other, and the chart is accordingly edited and displayed. At the same time, at a position at which the column or row is deleted, an identifier is displayed. Whether to display the identifier is optionally selected by a user. In addition, when the coordinates inputting means (3) on the identifier is touched, the deleted column is restored and displayed at the original position. When there are deleted plural columns, an optional column is selectively designated from the plural columns so that only the designated column is restored. Further, to designate a column, using an identifier in the form of a menu display, the coordinates inputting means on the menu display corresponding to the designated column is touched and designated.
