Abstract

A program is disclosed that reduces the amount of data transferred to a Chart Display screen while maintaining most of the information that was included in the original line chart. The on-screen space required for the chart display is reduced. Value range, local trend, and an event contained in a group of raw data points are represented by a vertical bar. The bar width is smaller on one side to indicate a trend. Color coding of one side of the bar is used to indicate an event in the raw data.
