Access Times and Data
Convert the Day variable to categorical. The categorical data type is designed for data that consists
of a finite set of discrete values, such as the names of the days of the week. List the categories so
they display in day order. Use dot subscripting to access variables by name.
bikeData.Day = categorical(bikeData.Day,{'Sunday','Monday','Tuesday',...
'Wednesday','Thursday','Friday','Saturday'});
In a timetable, the times are treated separately from the data variables. Access the Properties of
the timetable to show that the row times are the first dimension of the timetable, and the variables
are the second dimension. The DimensionNames property shows the names of the two dimensions,
while the VariableNames property shows the names of the variables along the second dimension.

By default, table2timetable assigned Timestamp as the first dimension name when it converted
the table to a timetable, since this was the variable name from the original table. You can change the
names of the dimensions, and other timetable metadata, through the Properties.
Change the names of the dimensions to Time and Data.
