Filters in Widgets

Qrvey provides filtering to refine data based on your needs. When embedding Qrvey Widgets into your system, you may need to combine Qrvey’s filters with your own set of filter controls. This article walks you through the steps needed to pass the values of your own filters to embedded Qrvey widgets. For an general introduction to filters, please see Working with Interactive Filters.

You can pass values to Qrvey’s widgets to filter charts or pages depending on your needs using the Filter Object Structure, as described below. The structure is passed as part of the supported widget’s configuration object as userFilters and it can contain an array of filters with the global scope by default.

The Filter Object

var config = {
    attribute1: value1,
    attribute2: value2,
    ...,
    "userFilters": { "filters": [...] }          
  }

Filters Object

Property	Type	Required	Description
operator	String	No	Default AND. Each filter requires a boolean logic to refine the data based on the user’s criteria. Allowed values: AND OR
expressions	Array	Yes	It’s a list of filter criteria to refine the data. Each item in the collection includes one or multiple Expressions Objects.

Expressions Object

Property	Type	Required	Description
qrveyid	String	No	Represent the dataset ID used to refine the data.
questionid	String	No	Represent the dataset’s column ID used to refine the data, should belong to the qrvey defined above.
questionType	String	Yes	It’s only required if the column used to refine the data is a FORMULA or a BUCKET; otherwise, it is optional. Allowed values: FORMULA BUCKET
validationType	String	Yes	The field represents the operand for filtering. Allowed values: EQUAL NOT_EQUAL CONTAIN NOT_CONTAIN END_WITH NOT_END_WITH START_WITH NOT_START_WITH RANGE IS_EMPTY * IS_NOT_EMPTY
property	String	No	When using complex data types like the ones defined inside Webforms, Quizzes, or Surveys, it’s required. Please refer to Complex Properties for a complete list of supported values.
groupValue	String	No	Default ‘day’. Only applies when you want to group date values. Allowed values: year month quarter week day hour minute second
value	Array	Yes	List of values used to filter the data. Qrvey will return all the records that match the criteria defined in the filter. Depending on the column’s data type, you may require additional parameters. Strings "value": [ "United States" ] Number or Date* **lt**: Less than.* **lte**: Less than or equalto.* **gt**: Greater than.* **gte**: Greater than or equal to. "value": [ { "gt": "10507.231" } ] "value": [ { "lte": "11/30/2016", "gte": "05/15/2014" {"}"} ]

Example: A Simple Filter

The following example shows the filter structure for a simple range filter on a numeric column:

Sample Filter: COLUMN_ID BETWEEN 10 AND 15.

...
"userFilters": {
      "filters": [
       {
         "operator": "AND",
         "expressions": [
           {
          "qrveyid": "QRVEY_ID",
             "questionid": "COLUMN_ID",
             "validationType": "RANGE",
             "value": [
               {
                 "lte": 15,
                 "gte": 10
               }
             ]
           }
         ]
       }
     ]
   }

Example: Filter Multiple Columns

The following example shows the filter structure for three filters with different columns and conditions.

Sample Filter:
COLUMN_ID_1 BETWEEN 05/15/2014
AND
11/30/2016
AND
COLUMN_ID_2 EQUAL ‘United States’ AND COLUMN_ID_3 GREATHER_THAN 10507.231
