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.


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

Easy-to-use commands for analyzing your data include a variety of basic statistics, Student t-test, ANOVA, and Wilcoxon. Use the Formula entry window to manipulate your data using over 100 algebraic equations and statistical functions from convenient menus.

Error Bars

Add error bars to your plot where the error can be specified in a data column or can be calculated by KaleidaGraph.

Precise Curve Fitting

Apply a variety of curve fits to your plot. Nine generic fits are supplied, including Least Squares (Linear) Regression and Smoothing fits, plus a library of over 100 industry-specific formulas.
