Use this drop-down menu to select the way you want your data split. The default option will produce a single plot covering the entire range of the data. Selecting 'Hour' will produce an individual plot for each of the 24 hours throughout the day and so helps to represent diurnal differences. Selecting 'Weekday' will produce an individual plot for each day of the week and so is helpful in highlighting differences throughout the working week and weekends. Selecting 'Month' will produce an individual plot for each month of the year and so is helpful in highlighting differences throughout the year. Selecting 'Season' will split the plot into proper seasons showing the trend within seasons.
