<!--T:168--><div class="index-right">__TOC__</div> <!--T:69-->You can create expressions (formulas) directly in the dashboard components. It can thus display calculated values that are not present in the datasource file/spreadsheet.  <!--T:70-->To create the expression (formula) in the components, the component must support the addition of the special column ''Expression (Formula)''.  <!--T:71-->In TaticView , all columns in the data file can be used in expressions as long as they are also added to the component that will receive the expression.  <!--T:72-->Expressions allows In addition, it is also possible to manually use fixed numbers and texts in the case of comparative expressions.  <!--T:73-->Expression Example: <!--T:74-->* If the component has the columns ''Total Price'' and ''Quantity'', you can create and edit an expression to calculate the ''Unit Price''. Would be like this:** ''"Total Price"'' / ''"Quantity"''* In addition, you can use fixed values, such as:** ''"Total price"'' / 10  <!--T:75-->We just remember that currently TaticView only supports expressions whose numeric return.  <!--T:225-->Expressions support the backslash as [[FiltersEscapeChar|escape character]] rules so that names can contain the delimiting characters. <!--T:76-->Below are details about how the expressions work: == Basic structure of a Expression (Formula) == <!--T:77--> ==== Identifier ==== <!--T:226--> <!--T:227-->It is the name of the field or column involved in the expression, it must be delimited by double quotes. <!--T:228-->* Examples: "Average Price". "Screw 1\" philips", "Seler" ==== Value Operand ==== <!--T:78--> <!--T:79-->It's the numerical values. You can use both while values and decimal values. For decimal values, the decimal separator should be the point. <!--T:80-->* Examples: 1, 1.05, 2.55 <!--T:220-->* Important: Do not use thousand separator in numeric values. ==== Text Operand ==== <!--T:81--> <!--T:82-->It's the text operands. If you want to use this type of operand in a expression, you must delimit them by using programming languagethe single quotation mark (').  <!--T:83-->* Examples: 'John Snow', 'California', 'Spaghetti'  ==== Date Operand ==== <!--T:84--> <!--T:85-->These are values that express any date. To represent a date in expressions the behaviour is similar to text operands, i.e. the content must be surrounded by single quotation marks ('). However, the mask ''dd/MM/yyyy'' must be used. <!--T:86-->* Examples: '01/01/2019', '14/11/2019', '25/12/2019'  ==== Boolean Operand ==== <!--T:87--> <!--T:88-->They're operators of the true or false type.

The date;is created from year to day, ie the day must be valid for the month and year (considering 29/02, the year must be leap).
==== First day of ==== <!--T:51206-->Return the first day of a grouping. This function have two variationsSyntax:* '''First way''': Syntax: ''FIRST_DAY_OF NEW_DATE(<constant_groupingday>;<expression_datemonth>;<year>)''. Need two parameters, the first is the constant grouping in which you want to obtain the first dateExample: 0, 1, 2, 3 or 5 (see constants list) and the second is the anchor base date. '''Examples''': FIRST_DAY_OFNEW_DATE(01;4;DAY_FROM_TODAY(0)) - first day of year (0) from today (DAY_FROM_TODAY(0)), FIRST_DAY_OFDATE_PART(1;"Order Issued Date";0) - first day of month (1) based on the "Order Data";* '''Second way''': Syntax: ''FIRST_DAY_OF(<constant_grouping>;<constant_modify_date>;<modify_date_value>)''. Need three parameters, - Creates the first is the constant grouping in which you want to obtain the first date: 0, 1, 2, 3 or 5 (see constants list), the second is the modifier April day of the base date from today: 0, 1, 2, 3 or 5 (see constants list) and year determined by the third is current row in the amount to change the modifier. ''Issued Date'Examples''': FIRST_DAY_OF(1;0;-1) - first day of the current month (1) from last year (0;-1);column.
==== Last day of ==== <!--T:52-->
Return the last day of a grouping. This function have two variations:
* '''First way''':
Syntax: ''LAST_DAY_OF(<constant_grouping>;<expression_date>)''. Need two parameters, the first is the constant grouping in which you
want to obtain the last date: 0, 1, 2, 3 or 5 (see constants list) and the second is the anchor base date.
'''Examples''': LAST_DAY_OF(0;DAY_FROM_TODAY(0)) - last day of year (0) from today (DAY_FROM_TODAY(0)), LAST_DAY_OF(1;"Order Date") -
last day of month (1) based on the "Order Data";
* '''Second way''':
Syntax: ''LAST_DAY_OF(<constant_grouping>;<constant_modify_date>;<modify_date_value>)''. Need three parameters, the first is the
constant grouping in which you want to obtain the last date: 0, 1, 2, 3 or 5 (see constants list), the second is the modifier
of the base date from today: 0, 1, 2, 3 or 5 (see constants list) and the third is the amount to change the modifier.
'''Examples''': LAST_DAY_OF(1;0;-1) - last day of the current month (1) from last year (0;-1);
==== New date NUM_OF_DAYS function (Number of days) ==== <!--T:53207-->Create an object from a day, month and year. Syntax: ''NEW_DATE(<expression_day>;<expression_month>;<expression_year>)''. Need three parameters, the first is a valid day number (1 to 31), the second for a month (1 to 12) and the third is a year. The date is created from year to day, therefore, the day must be valid for the month and the year (considering 29/02, year must be bissextile). '''Examples''': NEW_DATE(1;4;DATE_PART("Order Date";0)) - create the first day of april from the year determined by the current row "Order Date" column;
==== Num of days ==== <!--T:54208-->Return Returns the number of days between two dates. Syntax: ''NUM_OF_DAYS(<expression_date1>;<expression_date2>)''. Need Therefore you need two date data type parametersdates. '''Examples''': NUM_OF_DAYS(FIRST_DAY_OF(0;"Order Date");"Order Date") - returns the number of days between the first day of year based on the "Order Date" column to the current day of the "Order Date" column, NUM_OF_DAYS(FIRST_DAY_OF(1;"Pay Date"); LAST_DAY_OF(1;"Pay Date")) - returns the number of days of the month of the "Pay Date" column;
==== Num of months ==== <!--T:55209-->Return the number of months between two dates. Syntax: ''NUM_OF_MONTHS NUM_OF_DAYS(<expression_date1date 1>;<expression_date2date 2>)''. Need two date data type parameters. Examples: '''Examples''': NUM_OF_MONTHSNUM_OF_DAYS(FIRST_DAY_OF(0;"Issued Date");"Issued Date") ''' - Return Returns the number of months between days from the first day of the year of , based on the "''Issued Date" '' column and , to the current month of day, based on the same column. '''NUM_OF_DAYS(FIRST_DAY_OF(1;"Issued Date" );LAST_DAY_OF(1;"Issued Date"))''' - Returns the number of days of the month, based on the ''Issued Date'' column;.
==== Previous date ==== <!--T:56-->
Return the closest exact previous date given a day and month.
Syntax: ''PREVIOUS_DATE(<expression_day>;<expression_month>)''. Need two parameters, the first is the day of month and the second the
month.
'''Examples''': PREVIOUS_DATE(1;4) - return the closest ''01/04'', in other words, until "01/04/current year", returns "01/04/last year",
after that returns "01/04/current year".
==== NUM_OF_MONTHS function (Number of months) ==== <!--T:211-->
=== Special variables === <!--T:57212-->Returns the number of months between two dates. Therefore, two date parameters are required.
<!--T:58213-->Special variables can be use with Syntax: NUM_OF_MONTHS(<date 1>; <date 2>)Example: '''NUM_OF_MONTHS(FIRST_DAY_OF(0; "Date"); "Date")''' - Returns the number of months between the first day of the year and the current month, based on the expressions''Date'' column.
<!--T:59-->
@count - Total number of lines returned in a table.
==== PREVIOUS_DATE function (Previous date) ==== <!--T:60214-->@row - current line number.
<!--T:61215-->@sum[Column] - Sum Given a day and a month, returns the last occurrence of that date. That is, if the current date (today) is less than the date passed by parameter (day / month), the return is the date (passed by parameter) of indicated columnthe previous year. Otherwise the return will be the current year date.
<!--T:62216-->@avg[Column] Syntax: PREVIOUS_DATE(<day>; <month>)Examples: '''PREVIOUS_DATE(15;12)''' - Avg of indicated column like @sum[Column] Considering that today's date is 14/11/2019, the last time December 15th occurred relative to today's date was 15/12/ @count2018, so this will be the return.
@prev[column] == Special Variables == <!- Previous row column value-T:217-->
<!--T:218-->
They can be used in conjunction with expressions to create complex calculations. Must be used in double quotation marks (“)
@accumCol[column] - Current accumulated column value. Useful to calculate Variable Avg ("@accumCol[column]" / "@row")
<!--T:219-->
* '''"@count"''' - Total number of rows that were returned for the component.
* '''"@row"''' - Current row number
* '''"@sum[column]"''' - Sum of the indicated column.
** Example: ''"@sum[Price]"'' - returns the sum of all rows in the ''Price'' column.
* '''"@avg[column]"''' - Average column, similar to ''"@sum[column]"'' / ''"@count"''
* '''"@prev[column]"''' - Row value before current row for this column
* '''"@totalRowValue[column]"''' - Value of total row, (if present), from this column.
* '''"@accumCol[column]"''' - Cumulative value from column to current row. Useful for calculating variable mean.
** Example: ''"@accumCol[column]"'' / ''"@row"''
