Python and GUI operation map¶

Use this table to find the public Python operation that corresponds to a GUI action.

Operation map¶

Edit or add coordinates	Edit ‣ Edit Coordinates in ImageTool data controls	`xarray.DataArray.assign_coords()`, such as `data.assign_coords(y=scale * data.y + offset)`, `data.assign_coords(temperature=20.0)`, or `data.assign_coords(label=("x", labels))`
Edit or add attributes	Edit ‣ Edit Attributes in ImageTool data controls	`xarray.DataArray.assign_attrs()`, such as `data.assign_attrs(sample_temp=20.0, note="checked")`
Swap dimensions	Coordinate editing dialog	`xarray.DataArray.swap_dims()`
Normalize interactively	ImageTool normalization dialog	Expressions like `data / data.mean(...)`
