Edit properties dialog

Advanced options to define and style elements

Updated at January 11th, 2022

Use the Element properties dialog to change element labels and calculate ratios.

By default, Protobi assumes each element corresponds to a data column with the same name as the element's key attribute, and uses that value directly.  But it's possible to override this in many ways.

Access the Advanced properties dialog by pressing on the element icon and choosing "More properties": 

Attribute Value Description


String Unique identifier for this element


String Label to use in place of key for display 
headline String Text describing key point of the element


String Text for longer descriptive title


String Text for footnote


Choice string|number|date|empty


String Name of data column to use as a data source for this element (defaults to key).  If specified, the value is read directly from that data column.


Name of an element to use as a data source for this element. If specified, data is interpolated from that element, after applying its coding, transforms, etc.


String List of child elements, separated by commas.


Choice Method


String Unique identifier of crosstab banner column(s)


String Delimiter to split values for this element.  For example "," will split a comma-delimited string into a multiple-response array. 
The special value "json" will parse the value as a JSON string.


String or number Numeric value or name of data column by which to divide the value of this element.  E.g. 100 will convert fractions between [0,1] to percents [0,100]


String or number Numeric value or name of data column by which to divide the value of this element.  This can be used to calculate on element as a ratio of another.


String or number
Numeric value or name of data column by which to weight the frequency of this element.  


Number Reference value by which to scale bars for this element. Useful when compacting to means, so that bars can be drawn for means relative to a some value.


Show or hide missing values.  Yes means always, No means never, and (default) means use current setting from [NA] button in toolbar


Show or hide the % sign in frequencies. 


Show or hide the tab from users with "View" access only. 


String Display format for this element's values using d3 format notation. E.g. "0%" will display fractions like 0.24 as percentages e.g. "24%"
