DasetView

From Adrosoft Lab:

DatasetView is a program that allows you to view, analyze and edit numeric data stored in ASCII-text files with amazing speed. Acquired data are inserted to a worksheet and are automatically represented on a chart. It is needed only one click to go from one file to another and to observe data in the tabular and graph forms.

DasetView enables to perform the express analysis of 'raw' data, deleting of meaningless data, correction of measuring values and excluding of blunders. In opposite other existing complex software, DasetView shows all numeric data in a chart at once even they have very different scales and so all changes with data are detectable well. You can save edited data and print a chart.
