The next-gen Grasshopper optimization tool.

Session Files

What is saved

A session file that saves the canvas state (plain JSON, saved as *-session.json) captures how the data is being viewed, not the data itself. It persists:

Item Description
Canvas layout Which widgets are placed, their positions/sizes, z-order, pan/zoom, and panel state.
Per-widget settings Every user-adjustable knob of every placed widget (selected axes/columns, cluster count, MCDM weights, histogram bin rule, normalization and log-scale toggles, feasibility filters, 3D camera poses, …).
Global view settings Colormap, filter ranges, pinned trials, hypervolume reference point, convergence indicator, help language.

The optimization data (journal / SQLite / CSV) and the results computed from it are not stored. Because no data is stored, a session can also be applied when you load a different optimization result.

Where to save and load

  • Save Session / Load Session toolbar buttons: save the current dashboard to a session JSON file, or restore one while keeping the currently loaded data.
