need to convert list of dates to count no. of dates by week
Basically I have 2 columns each with a list of dates in no particular order (and containing blank cells too), one planned date column and one actual date column. What I need to do is plot this on a graph, and since the number of dates has no set limit and I dont want to have to plot maybe 100 dates on the x axis, so i want to group them by week before plotting them, i.e. 10 dates for week ending 10th jan, 25 dates for week ending 17th jan etc I have a pivot table that counts how many of each date occurs, i.e. 10 x 2nd jan, 7x 3rd jan etc etc but it does not split them into weeks. im sure theres an easyish way of doing it so i can get the 2 lines on the graph for no. of planned dates each week and no. of actual dates each week, i just cant see it. thanks  neowok  neowok's Profile: http://www.excelforum.com/member.php...fo&userid=5940 View this thread: http://www.excelforum.com/showthread...hreadid=505716

=SUMPRODUCT((A2:A200="20060104"),(A2:A200<="20060110"))
gives a count for the week in those dates  HTH Bob Phillips (remove nothere from the email address if mailing direct) "neowok" wrote in message ...

hmmm that would work if i have a smallish, set number of weeks and i know what the weeks are, but this is a dynamic document where the date range is subject to change daily  neowok  neowok's Profile: http://www.excelforum.com/member.php...fo&userid=5940 View this thread: http://www.excelforum.com/showthread...hreadid=505716

Is the date a row field?
How about rightclicking on it and choosing choose Group and show detail. Then group by weeks. If excel's weeks are different than yours, you could use add a new column in the raw data and determine the week based on whatever rules you follow. Then use that in the pivottable. neowok wrote: Basically I have 2 columns each with a list of dates in no particular order (and containing blank cells too), one planned date column and one actual date column.

the dates are in 2 columns, i went to group but cant see how i could group them by week (no options for this) top few cells of one of the planned date column and 2 extra needed for the graph may look something like this if it all works Planned week ending numberof items 010106 010106 3 <blank cell 080106 2 <blank cell 150106 1 050106 260206 1 010106 010106 250206 <blank cell <blank cell 150106 030106 <blank cell etc etc the graph could then be based on the week ending and number of items column for the planned series, and then the same thing again for the actual series. I think i need to get an automated split of weeks in one column (B) (ending on say sundays) and then in column C, the number of dates in column A which falls during the week in column B if not that then some other way of getting the same sort of result just so I can draw the graph.  neowok  neowok's Profile: http://www.excelforum.com/member.php...fo&userid=5940 View this thread: http://www.excelforum.com/showthread...hreadid=505716

If your field has text or blanks, then you can't use that grouping.
Excel has a =weeknum() function that might be ok right out of the box. =if(a2="","",weeknum(a2)) ??? neowok wrote: the dates are in 2 columns, i went to group but cant see how i could group them by week (no options for this) top few cells of one of the planned date column and 2 extra needed for the graph may look something like this if it all works Planned week ending numberof items 010106 010106 3 <blank cell 080106 2 <blank cell 150106 1 050106 260206 1 010106 010106 250206 <blank cell <blank cell 150106 030106 <blank cell etc etc the graph could then be based on the week ending and number of items column for the planned series, and then the same thing again for the actual series.

hm might be able to use severla more columns and use weeknum. i can use a macro to copy the weeknum formula down for however many rows the dates go, then maybe make a pivot table of that column giving me a count of each weeknum, then somehow convert the weeknums into weeks that i can use as x axis labels and base the chart off the pivottable but without using a pivotchart. or something, but thats probly a bit too complicated to work hehe ill have to fiddle with it on monday  neowok  neowok's Profile: http://www.excelforum.com/member.php...fo&userid=5940 View this thread: http://www.excelforum.com/showthread...hreadid=505716

Or instead of using the week number, use the date of the first day in the week
(or the Friday of that week or...) neowok wrote: hm might be able to use severla more columns and use weeknum. i can use a macro to copy the weeknum formula down for however many rows the dates go, then maybe make a pivot table of that column giving me a count of each weeknum, then somehow convert the weeknums into weeks that i can use as x axis labels and base the chart off the pivottable but without using a pivotchart. or something, but thats probly a bit too complicated to work hehe ill have to fiddle with it on monday  neowok  neowok's Profile: http://www.excelforum.com/member.php...fo&userid=5940 View this thread: http://www.excelforum.com/showthread...hreadid=505716  Dave Peterson

need to convert list of dates to count no. of dates by week
ok ive got 2 columns populated with planned dates and actual dates, all converted to the friday of each week so i can get a count of how many were planned/actual in a given week. the major problem i have now is trying to plot the 2 series on the line graph. to get the counts of each date ive had to use 2 pivot tables, one that counts the dates in planned column and one counting the dates in the actual column. 2 problems with this are, i cant plot a graph from 2 different pivot tables, and even if i could, the ranges of weeks do not match, i.e. the 2 pivot tables show planned count actual count 6 jan 06 6 18 nov 05 24 20 jan 06 2 25 nov 05 13 27 jan 06 2 2 dec 05 37 3 feb 06 1 9 dec 05 12 16 dec 05 12 23 dec 05 10 20 jan 06 2 so as you can see, i somehow need to group up the dates from both planned and actual to use as the X axis catagories, and then plot the 2 series under the correct dates  neowok  neowok's Profile: http://www.excelforum.com/member.php...fo&userid=5940 View this thread: http://www.excelforum.com/showthread...hreadid=505716

I'm not sure if this fits, but if you made the planned/actual category a column
field in the pivottable, would it work ok? neowok wrote: ok ive got 2 columns populated with planned dates and actual dates, all converted to the friday of each week so i can get a count of how many were planned/actual in a given week. the major problem i have now is trying to plot the 2 series on the line graph. to get the counts of each date ive had to use 2 pivot tables, one that counts the dates in planned column and one counting the dates in the actual column. 2 problems with this are, i cant plot a graph from 2 different pivot tables, and even if i could, the ranges of weeks do not match, i.e. the 2 pivot tables show planned count actual count 6 jan 06 6 18 nov 05 24 20 jan 06 2 25 nov 05 13 27 jan 06 2 2 dec 05 37 3 feb 06 1 9 dec 05 12 16 dec 05 12 23 dec 05 10 20 jan 06 2 so as you can see, i somehow need to group up the dates from both planned and actual to use as the X axis catagories, and then plot the 2 series under the correct dates  neowok  neowok's Profile: http://www.excelforum.com/member.php...fo&userid=5940 View this thread: http://www.excelforum.com/showthread...hreadid=505716  Dave Peterson

thanks for replies. i think i have a solution that works now using a few dummy columns with various formulas in to reduce it down to the required data for the graph.  neowok  neowok's Profile: http://www.excelforum.com/member.php...fo&userid=5940 View this thread: http://www.excelforum.com/showthread...hreadid=505716
