Visualise your data
KaleidaGraph is used by scientists, researchers and engineers at top research centers worldwide.
Flexible Data Entry
Begin your analysis by either opening a data file or entering data using the keyboard. Excel files may be opened directly. Tab, space, and other delimited text files use a very flexible import facility.
Fast and Versatile Graphing Choices
Create plots quickly and easily using entire data columns or just a selection of your data. Data can be spread across multiple files and seamlessly integrated into one powerful graph to best explain your work.
Complete Control over Every Plot Option
To customize every detail of your plot, simply click directly on each plot element and make the logical choices to best illustrate your data. You can modify the axis limits, text labels, tick marks, legend, line thickness, marker shapes & sizes, and more.
Templates
When you create a graph you like, save it as a template so you can use it with repetitive data sets for a consistent presentation.
Analyse your findings
Powerful Data Analysis and Manipulation
Easytouse commands for analyzing your data include a variety of basic statistics, Student ttest, ANOVA, and Wilcoxon. Use the Formula entry window to manipulate your data using over 100 algebraic equations and statistical functions from convenient menus.
