KaleidaGraph: A Computer Program that Generates

Histograms-and Much More
Fall 1977

Long-time IPS users will recall the IPS Coursware, which asked pertinent questions, and checked measurements and calculations. The most appreciated feature of the program was the ability to construct histograms. Since the Courseware ran on Apple IIe� computers, it is obvious why it was not updated along with the most current Editions.

Today, users demand versatile, multipurpose software. Therefore, rather than creating new dedicated IPS software, we looked for a quality graphing program that incorporates a routine for constructing histograms the way IPS students learn to construct them. The result is KaleidaGraphTM 3.09, Student Edition, published by Synergy Software in Reading, PA. The improvement in the quality of the output can be seen by comparing Figures A and B with the corresponding figures on page 34 in the text. As discussed in the IPS text, the Student Edition of KaleidaGraph lets the user select the bin size, the reference value, and the location of the reference value (center or border).

KaleidaGraph is very powerful, fast, and user friendly. It is widely used by engineers and scientists. In fact, many of the graphs in the text were created with KaleidaGraph. The Student Edition of the software will easily satisfy all the data analysis and graphing needs of your students throughout high school in biology, chemistry, physics, and other courses.

 

The Student Edition of KaleidaGraph accommodates up to 20 columns and 512 rows in each data window-over 10,000 values in all! This is more than enough to compare the results of 15 classes. The full version of KaleidaGraph accommodates over 8 million data points but does not include the IPS histogram routine, and costs substantially more.

The Student Edition of KaleidaGraph is available on a CD ROM disk that contains both Macintosh@ and Windows@ versions. The Student Edition is available only from Science Curriculum Inc. Another example of a KaleidaGraph histogram.
