"period=range" parameter

[JLuc]

https://developer.matomo.org/api-reference/reporting-api documents 'period' and 'date' API argument :

• for period=range it states an example: « to request a report for the range Jan 1st to Feb 15th you would write period=range&date=2011-01-01,2011-02-15 »
• date documentation includes this :

Note: if you set 'period=range' to request data for a custom date range, 
the API will return the sum of data for the specified date range. 
When 'period=range', the following keywords are supported for the parameter 'date':
- lastX
- previousX
- YYYY-MM-DD,YYYY-MM-DD, both dates can be replaced with magic keywords 
(the first one does not support today and yesterday). 
eg. YYYY-MM-DD,today, lastMonth,YYYY-MM-DD or lastYear,lastWeek

But when date is last10, is it 10 days ? weeks ? months ? years ?

Documentation should mention what parameter holds 'day', 'week', 'month' or 'year' when period is range.

It could be date=last10 is not possible when period=range, and in such a case documentation should be fixed also.

Thank you for taking the time to create this issue @JLuc .The documentation does need clarification.

When using period=range together with date=lastX Matomo uses a unit of Day by default.
This means that lastX can only be used for a range of Days.

Otherwise lastX can be used for intervals specified in the period value.
For example, period=month&date=last12 would produce a report with metrics for each month of the last 12 months...
