Graphical Visualization of Historical Data

摘要

In this work we present a graphic tool that permits, in a flexible and easy way, the visualization of data bases that contain historical information from analogical channels. The tool consists basically of two parts: a) Preprocess of data: that allows to apply different functions (smoothing, gradient, hysteresis, etc.) of data correction with the purpose of diminishing the possible reading errors when measuring an event b) Graphical Representation through a resemblance of pencil and paper: that allows to represent several curves in a same graphic, several graphics simultaneously, zoom, graphics of distribution, total flexibility in configuration of intervals and visualization ranks, individualized configuration by curve, grids, etc.
