The year values are updated in the visualization.The data is rolled up to the highest level of detail.
You could have a date field with year, month, and day for each value.New date values can be created with a date function from the existing values.For any existing date value, you can find the beginning of the quarter.
Q1 started on January 1 if the original date is 3/27/2011.Q2 started on April 1, four months into the year, if the original date is '5/3/2011'.

The ISO 8601 format is an international standard for calculating dates and times that are different from the Gregorian calendar due to how the first week of a year is calculated.The user can define when a week begins in the Gregorian calendar.The week always begins on a Monday.
The first week of the year is counted as starting on the 1st of January regardless of where in the week it occurs.Week 1 will have one day and Week 2 will start on the following Sunday if January 1st falls on a Saturday.
Week 1 of a new year starts on a Monday and has four or more days in January.Week 1 will not begin until the following Monday, January 3rd if January 1st falls on a Saturday.It's important that there are a consistent number of days in Week 1 of a new year.
