GroIMP supports the creation and visualization of datasets, which are simple tables used to store and track numerical data during simulations. Each dataset consists of rows called data series, and values are added to individual cells using code.

Datasets are accessible in both the GUI (via the Datasets Explorer) and in RGG code using the DatasetRef class. Titles for columns can be set, and data can be visualized using the chart() function with plot types like XY_PLOT.

Datasets can be exported to external files and are persistent across simulation runs unless explicitly cleared.

For code examples see the datasets tutorial.
