Synopsis
Return the dimensions of the data set.
Syntax
get_dims(id=None, filter=False) id - int or str, optional filter - bool, optional
Examples
Example 1
Display the dimensions for the default data set:
>>> print(get_dims())
Example 2
Find the number of bins in dataset 'a2543' without and with any filters applied to it:
>>> nall = get_dims('a2543')
>>> nfilt = get_dims('a2543', filter=True)PARAMETERS
The parameters for this function are:
| Parameter | Definition |
|---|---|
| id | The data set. If not given then the default identifier is used, as returned by `get_default_id` . |
| filter | If True then apply any filter to the data set before returning the dimensions. The default is False . |
