# set_data¶

sherpa.astro.ui.set_data(id, data=None)

Set a data set.

Parameters: id (int or str, optional) – The data set. If not given then the default identifier is used, as returned by get_default_id. data (instance of a sherpa.Data.Data-derived class) – The new contents of the data set. This can be copied from an existing data set or loaded in from a file (e.g. unpack_data).

copy_data()
Copy a data set to a new identifier.
delete_data()
Delete a data set by identifier.
get_data()
Return the data set by identifier.
load_data()
Create a data set from a file.
unpack_data()

Notes

The function does not follow the normal Python standards for parameter use, since it is designed for easy interactive use. When called with a single un-named argument, it is taken to be the data parameter. If given two un-named arguments, then they are interpreted as the id and data parameters, respectively.

Examples

>>> d1 = get_data(2)
>>> set_data(d1)


Copy the background data from the default data set into a new data set identified as ‘bkg’:

>>> set_data('bkg', get_bkg())
