# hitcount3

How to download and try this example

    Usage: pl -gif hitcount3.htm

    Uses the data file hitcount.dat

    See also hitcount.

    This example illustrates datetime scaling with time windowing.
    Only the hours from 8 to 18 (6pm) are shown for each day.

    #proc getdata
    file: hitcount.dat
    // the following filter strips seconds from the time value,
    // then builds a ddMmmyyyy date and connects it with the time
    // value (separated by a dot)
    pf_fieldnames: datetime nbytes
    filter:
     	##set TIME = @@4
    	##set TIME = $substring(@@TIME,1,5)
    	@@3@@2@@6.@@TIME @@7

    // use proc processdata to sum nbytes for each unique time value
    #proc processdata
    action: count
    fields: datetime nbytes
    fieldnames: datetime nbytes

    // #proc print
    // label: After transform: nrecords=@NRECORDS nfields=@NFIELDS

    // set up plotting area with datetime in X and autorange on the y axis.
    // do x axis showing day of week and y axis
    #proc areadef
