I'm using monthly data and trying to display YoY% calculations.
However, my code is not robust for different end-of-month dates caused by leap years, I think.
Value YoY% 2 =
VAR START_DATE = DATEADD('DATA'[Date], -12, MONTH)
RETURN
DIVIDE(SUM(DATA[Value]), CALCULATE(SUM(DATA[Value]),START_DATE))-1
I'm very much a power BI novice. Thank you for your help.
Try the following:
Value YoY% 2 =
VAR Curr_Year = YEAR(SELECTEDVALUE(DATA[Date]))
VAR Last_Year = Curr_Year - 1
RETURN
DIVIDE(
CALCULATE(SUM(DATA[Value]), FILTER(DATA, YEAR(DATA[Date]) = Curr_Year)),
CALCULATE(SUM(DATA[Value]), FILTER(DATA, YEAR(DATA[Date]) = Last_Year))
)

I have the following Table:
It represents cases on which a certain Team is working on over the Time until the case is closed.
And there is also a Date Table over column Date.
I would like to cumulative count the open cases until the selected date.
So I used this measure:
CountOpen =
VAR CurrentDate = MAX('Date'[Date])
VAR Closed =
CALCULATE(
DISTINCTCOUNT(Tabelle1[case]),
ALL('Date'),'Date'[Date]<=CurrentDate,Tabelle1[Status_Open]="0")
VAR OpenAll =
CALCULATE(
DISTINCTCOUNT(Tabelle1[case]),
ALL('Date'),'Date'[Date]<=CurrentDate,Tabelle1[Status_Open]="1")
RETURN OpenAll-Closed
And it works for the overall view. But for the view within the Dimension CurrentTeam it's not correct:
It should be:
a = 0
b = 1
c = 0
So... this is actually quite tricky, you have to pick the latest status per case up to the selected date. In my solution I create a table, with a column R which ranks the cases per date, then in the result I filter for those depending on which team you have selected.
Measure is below:
VAR CurrentDate = MAX('Date'[Date])
VAR CurrentTeam = SELECTEDVALUE(Tabelle1[CurrentTeam])
VAR tbl =
SUMMARIZE(
FILTER(ALL('Tabelle1'), 'Tabelle1'[Date] <= CurrentDate),
Tabelle1[case],
Tabelle1[CurrentTeam],
Tabelle1[Status_Open],
Tabelle1[Date],
"R",
VAR c = MAX(Tabelle1[case])
VAR d = LASTDATE(Tabelle1[Date])
RETURN
CALCULATE(DISTINCTCOUNT(Tabelle1[Date]),
ALLSELECTED(Tabelle1),
Tabelle1[case] = c,
Tabelle1[Date] >= d)
)
RETURN SUMX(
FILTER(tbl,
[R] = 1 &&
(ISBLANK(CurrentTeam) || [CurrentTeam] = CurrentTeam) &&
[Status_Open])
, 1) + 0 //+0 is here to show 0 where it would be blank
I'm currently working with jquery FullCalendar plugin to create a specific calendar.
One of my tasks I have to work out is how to get any given specific day for the month.
I'm currently using Coldfusion 10 for the server side so I'm wondering is there any specific way of getting every instance of a Tuesday into an array of dates?
Ideally I would like to do this on the server side and populate the calendar plugin.
My issue is primarily trying to source every specific day of a calendar month.
Any advice greatly appreciated.
The firstXDayOfMonth() UDF on CFLlib allows you to find the first of a given day-of-week in a given month. From there you just need to loop from that date adding 7 each iteration until the month is no long the selected month.
theMonth = month(now());
startDate = firstXDayOfMonth(3, theMonth, year(now()));
tuesdays = [];
for (date=startDate; month(date) == theMonth; date +=7){
arrayAppend(tuesdays, dateAdd("s",0, date)); // this just converts date from a number back to a date
}
writeDump(tuesdays);
Update:
Actually the approach for that UDF on CFLib is terrible. Use this variation instead:
function firstXDayOfMonth(dayOfWeek,month,year){
var firstOfMonth = createDate(year, month,1);
var dowOfFirst = dayOfWeek(firstOfMonth);
var daysToAdd = (7 - (dowOfFirst - dayOfWeek)) MOD 7;
var dow = dateAdd("d", daysToAdd, firstOfMonth);
return dow;
}
I'll update the UDF on cflib a bit later: I need to write some decent unit tests for it first, and am a bit busy # the moment.
The Short Version:
At this time, there is not a function in CF that gets all the Tuesdays. But here's an easy way to do it:
// assuming a year and month are defined already
var firstDayOfMonth = createDate( year, month, 1 );
var targetDayOfWeek = 3; // Tuesday is 3 if Sunday is 1
var dayOfWeekArray = []; // This is the outcome.
// loop through each day of the month adding the target days to the array.
for( i = 1; i LTE daysInMonth( firstDayOfMonth ); i++){
var loopingDate = createDate( year, month, i );
if( dayOfWeek( loopingDate ) == targetDayOfWeek ){
ArrayAppend( dayOfWeekArray, loopingDate );
}
}
dayOfWeekArray is an array of every Tuesday of a month.
More Detail:
Your title and post seem to conflict as far as what you're looking for, so I'm going to stick with the title, since that's why I came here...
Here's what you can do to find all the Tuesdays in a month:
Create a date Object
Loop through the days in the target month using the date Object
If the current day is Tuesday, add it to an array
Boom, you got all the Tuesdays of a month in an array
Here's the code I used (cfscript):
// assuming a year and month are defined already
var firstDayOfMonth = createDate( year, month, 1 );
var dayOfWeekArray = [];
var targetDayOfWeek = 3; // Tuesday is 3 if Sunday is 1. Do a quick writeDump in the loop if you're not sure.
for( i = 1; i LTE daysInMonth( firstDayOfMonth ); i++){
var loopingDate = createDate( year, month, i );
if( dayOfWeek( loopingDate ) == targetDayOfWeek ){
ArrayAppend( dayOfWeekArray, datePart( "d", loopingDate );
// ArrayAppend( dayOfWeekArray, loopingDate ); - use this if you'd rather have the whole date object
}
}
This gives you dayOfWeekArray which will be the date of each Tuesday of a particular month. For instance, this month (Jan 2019) will be [1, 8, 15, 22, 29]. You can change this to be the entire date object if you want - that's what I did in the short version at the top.
What I am trying to do here is this - I want to give index to only the workdays in each week.
So, if in a week, Monday and Wednesday are holidays, then Tuesday should get 1, Thursday should get 2, Friday should get the index 3. Otherwise, in a normal week without any holidays, Monday should get 1, Tuesday 2, Wednesday 3, and so on ...
Here is the code I have written (I haven't coded in years now, so please pardon the crude approach)
Sheet 'Holidays' contains a list of holidays in the column B starting from row 2
Variable date is the date for which I want to find out the index for
Variable dayOfTheWeek is the number of day of 'date' counted from last Sunday, so if date is a Monday, dayOfTheWeek is 1; if date is Tuesday, dayOfTheWeek is 2, and so on ...
function indexOfWorkdayOfTheWeek (date, dayOfTheWeek, lastSundayDate)
{
var activeSheet = SpreadsheetApp.getActiveSpreadsheet();
var activeCell = activeSheet.getActiveRange();
var activeRow = activeCell.getRowIndex();
var activeColumn = activeCell.getColumn();
var count = 1;
for (var j = 1; j < dayOfTheWeek; j++)
{
var date2 = lastSundayDate.valueOf() + j*86400;
Logger.log('Date ' + j + ' is:' + date2);
Logger.log('Last Sunday is:' + lastSundayDate);
if (holidayOrNot(date2) == true)
{
}
else
{
count = count + 1;
}
}
return count;
}
function holidayOrNot(date2)
{
var holidaysSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Holidays');
var listOfHolidays = holidaysSheet.getSheetValues(2, 2, 95, 1);
var isDateMatch = false;
for (var k = 0; k < 90; k++)
{
if (date2 == listOfHolidays[k].valueOf())
{
isDateMatch = true;
break;
}
else
{
continue;
}
}
return isDateMatch;
}
I think the problem is two-fold here:
The date2 calculation isn't working for some reason (var date2 = lastSundayDate.valueOf() + j*86400;)
The function holidayOrNot is returning false, no matter what, even if it encounters a holiday ... the condition date2 == listOfHolidays[k] isn't working for some reason...
Help would be appreciated!
maybe this method below could help you in your calculations, it returns an integer corresponding to the day of the year so if you apply this to your holidays days and compare to the days of interest it could be a good way to find matches.
here it is, just add these lines outside of any function in your script (so you can use it anywhere) then use it like this :
var d = new Date().getDOY();
Logger.log(d)
Here the method :
Date.prototype.getDOY = function() {
var onejan = new Date(this.getFullYear(),0,1);
return Math.ceil((this - onejan) / 86400000);
}
Assuming that lastSundayDate is being passed around correctly, I see a glaring problem:
lastSundayDate.valueOf().
valueOf() on Date objects returns the primitive value... it looks like you're going for adding a day to the date (86400 seconds * j)? I can't tell what the logic is supposed to be here. But the valueOf() date2 is definitely giving you an integer something like: 1384628769399 (see here).
What you really want to accomplish is something like Date.getDay(), or something similar so that you can add hours, days, etc. to the original Date. This is likely the source of all your problems.
What you can do is read the Mozilla Developer Network documentation on Date objects to see all of the functions on Dates and their uses. You can greatly simplify what you're trying to do by using these functions, instead of doing abstract operations like j * 86400.
It should also be noted that you can do simple operations such as the following, to add 4 hours to the current Date (time):
var myDate = new Date();
Logger.log(myDate); // ~ console.write
var laterDate = new Date(myDate.setHours(myDate.getHours() + 4));
Logger.log(laterDate); // ~ console.write
which gives the following:
[13-11-16 14:13:38:947 EST] Sat Nov 16 14:13:38 GMT-05:00 2013
[13-11-16 14:13:38:954 EST] Sat Nov 16 18:13:38 GMT-05:00 2013
Working with dates can be tricky - but it's always best to use the simplest methods that are available, which are built into the Date objects themselves. There are also numerous other libraries that provide extended functionality for Dates such as Date js.
If you're still running into your problem after attempting to try using methods I displayed above, please run your script and post both the Execution Transcript and the content of the Logger so that I can help you narrow down the issue :)
how to find how much number of weeks are there in a month, i.e either a month is having 4 or 5 weeks , how it can be calculated from current date supplied.
Thanks
For iPhone See: Number of weeks in month For web/Javascript, See: Get Weeks In Month Through Javascript. Algorithm is simple (from above page):
function weekCount(year, month_number) {
// month_number is in the range 1..12
var firstOfMonth = new Date(year, month_number-1, 1);
var lastOfMonth = new Date(year, month_number, 0);
var used = firstOfMonth.getDay() + lastOfMonth.getDate();
return Math.ceil( used / 7);
}
I need to convert a datenumber to its closest end-of-month date. I found an online link but it is very inefficient for a large matrix (at http://www.mathworks.com/matlabcentral/fileexchange/26374-round-off-dates-and-times). Does Matlab (Financial Toolbox) has an inbuilt function for this? I couldn't find it.
date_in = 734421 ;
somefunction(date_in) --> Sept 2010
Thanks!
Basically, it sounds like you are asking for whether a given date is closer to the preceding or following month. You can greatly simplify the logic involved if you use the functions EOMDAY to find the date for the end of the month and ADDTODATE to shift the current month up or down by one. Here's an example function that takes a date number as input:
function closestString = closest_month(dateNumber)
dateVector = datevec(dateNumber);
daysInMonth = eomday(dateVector(1),dateVector(2));
if dateVector(3) > daysInMonth/2
dateNumber = addtodate(dateNumber,1,'month');
else
dateNumber = addtodate(dateNumber,-1,'month');
end
closestString = datestr(dateNumber,'mmm yyyy');
end
I had some errors in my previous version. Here's the logic incorporated into a function. It also checks for the month and updates accordingly.
function out = roundMonth(dateNumber)
dateVector = datevec(dateNumber);
day = dateVector(3);
month = dateVector(2);
year = dateVector(1);
month = month + sign(day - 15 + double(~(month-2)))...
+ double(~(day-15 + double(~(month-2))));
dateVector(1) = year + double((month-12)==1) - double((1-month)==1);
dateVector(2) = mod(month,12) + 12*double(~mod(month,12));
out = datestr(dateVector,'mmm yyyy');
EXAMPLES:
1.
roundMonth(datenum('10-Oct-2010'))
ans =
Sep 2010
2.
roundMonth(datenum('20-Oct-2010'))
ans =
Nov 2010
3.
roundMonth(datenum('20-Dec-2010'))
ans =
Jan 2011
4.
roundMonth(datenum('10-Jan-2010'))
ans =
Dec 2009
