Create a false calendar

[#1]

Der all,

I read in one of the forum topics that it is posible to create a false calendar and link data from an existing calendar, so dates without any data are shown in the graf.

Can somebody explain me how to create a false calendar and how to conect it to the other one. Thanks in advance.

You could do something like bellow. Just remember to change the charts so that zero-values are shown (on the Presentation tab).

// Some orders
DataTable:
LOAD OrderNo, date#(Date,'YYYY-MM-DD') as Date, Value INLINE [
OrderNo, Date, Value
1, 2009-10-12, 27
2, 2010-01-04, 37
3, 2010-12-10, 34
4, 2009-05-08, 82
5, 2009-06-08, 18
];

// Find max and min dates
MaxMin:
Load
max(Date) as maxDate,
min(Date) as minDate
resident DataTable;

// Put in variables
Let minDate = FieldValue( 'minDate', 1 );
Let maxDate = FieldValue( 'maxDate', 1 );

// Create temp and calculate all dates between min and max
Calendar_tmp:
Load
date($(minDate)+RowNo()-1) as Date
autogenerate($(maxDate)-$(minDate)+1);

// Calculate month, year, etc
Calendar:
Load
Date,
month(Date) as Month
// And so on...
resident Calendar_tmp;
drop table Calendar_tmp;
