Abstract : The method of the present invention minimizes the time required to display a portion of a time sampled data file. A plurality of compressed data files are generated based on the time sampled data file. Each of the compressed data files is defined by a corresponding unique compression ratio such that each compressed data file contains fewer data points than the original time sampled data file. Each compressed data file characterizes the original time sampled data file. The compressed data files are stored in a data storage device for subsequent retrieval. A resolution factor is defined for each of the compressed data files. One of the compressed data files is then selected based on the resolution factor and the portion of the time sampled data file requested for display. The selected compressed data file is transferred from the data storage device to the display device.
