ixdat provides a powerful object-oriented interface to experimental data, especially in-situ or online experimental data for which it is of interest to combine data obtained simultaneously from multiple techniques. Being centered around timestamps, ixdat allows you to smoothly connect data recorded with different techniques.

The concept is illustrated in the figure below: A measurement object interfaces with the data from one or more techniques, which can be treated using built-in methods, or can be retrieved in the form of an array, for maximum flexibility. Data in various formats is read in with the corresponding reader and can be plotted with a plotter, exported with an exporter (e.g. for treatment using other tools), or simply stored for later use in a database connected to ixdat. To allow for this broad functionality, ixdat comes with a pluggable reader interface for importing your data format, as well as pluggable exporter and plotter and database.

Design: pluggability

Get started today with one of the tutorials available under Tutorials. If you’re curious about the details of ixdat’s structure and the available readers, plotters and exporters, check out the section Diving deeper.
