Dataplot

Dataplot is a multi-platform application made for scientific visualization, statistical analysis, and non-linear modeling.

It enables experienced users, like researchers and analysts to customize, model, view, evaluate, monitor and optimize scientific and engineering processes from a user-friendly interface.

After an uncomplicated setup operation that takes just a few seconds, you are greeted by a console interface split into two panes for inputting data and examining the dataplot graphics, respectively.

A complete list of commands that can be entered into the application can be found at the developer's website. It covers raw and analysis graphics (e.g. color customization, plotting functions, sizing), presentation and summary graphics (e.g. math functions, pie charts, histograms), diagrammatic graphics (e.g. geometric and electrical symbols), graphical and exploratory data analysis (e.g. probability and bootstrap plots), time series analysis (e.g. lag and auto-correlation plots), smoothing, fitting, experiment design, and others.

Once the plot is generated, you can check it out in the secondary pane. Dataplot lets you select text, graphics or all elements from the commands pane, copy and paste them, enter full screen mode, as well as print information or save it to bitmap image files.

We haven't come across any issues in our tests as far as stability is concerned, thanks to the fact that the software utility didn't hang, crash or display error messages. It executed commands swiftly while remaining light on system resources, using low CPU and RAM.

Taking into account its versatility towards commands, Dataplot proves to be a feature-rich and straightforward application for helping you perform scientific, engineering, statistical, mathematical, and graphical analysis. Plus, it's freeware.
