If a Text column is used as part of a function in Formula Entry, incorrect values will be calculated. If the values are being read from the Text column, KaleidaGraph will read the value as 1 + index(). If you try to store the results of a formula in a Text column, the same value will appear in all of the cells of that column.
KaleidaGraph is a thoughtfully designed graphing and data analysis application for research scientists, as well as for those in business and engineering fields. It produces publication-quality graphs, and easily converts the most complex data into a functional display.
