If the data has Excel’s m/d/y h:m format, KaleidaGraph will interpret the time portion as minutes:seconds instead of hours:minutes. To import the dates correctly, use a custom date format in Excel of m/d/y/ h:m:s in the Number dialog under the Format menu. Then copy and paste the data.
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.
