# hitcount2

How to download and try this example

    Usage: pl -gif hitcount2.htm

    Uses the data file hitcount.dat

    See also hitcount.

    Thanks to Jim Arnott for suggesting the proc processdata count feature,
    the idea for this example, and for the bit of prodding on the datetime
    scale type.

    #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)
    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
    showresults: no

    #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
