Docs: GoDoc

etview provides GUI Views of etable.Table and etensor.Tensor structures using the GoGi View framework, as GoGi Widgets.

Add this to import to get these views to be registered with the Cogent Core Value system:

	_ "github.com/goki/etable/v2/etview" // include to get gui views

  • TableView provides a row-and-column tabular GUI interface, similar to a spreadsheet, for viewing and editing Table data. Any higher-dimensional tensor columns are shown as TensorGrid elements that can be clicked to open a TensorView editor with actual numeric values in a similar spreadsheet-like GUI.

  • TensorView provides a spreadsheet-like GUI for viewing and editing tensor data.

  • TensorGrid provides a 2D colored grid display of tensor data, collapsing any higher dimensions down to 2D. Different views.ColorMaps can be used to translate values into colors.
