Dynamic Items

Dynamic items are content items that are computed or collected automatically rather than being created as static pieces of content. These include counters, averages, computed values, and data bins that calculate or aggregate data from participant responses or other sources.

Counter

Use a Counter result item to display a numeric count or value with customizable styling. Counter displays a numeric value that can count responses, show totals, or display any numeric metric. The value can animate when it changes.

Settings

Setting	What it does
Initial value	Set the starting value for the counter
Transition time	Adjust the animation speed when the value changes (in milliseconds)

Styles

Setting	What it does
Font size	Set the size of the displayed number
Font color	Choose the color for the number

Average

Use an Average result item to display the average (mean) value from numeric responses.

Inputs

Compatible inputs: Works with numeric answer items and computed values

Settings

Setting	What it does
Label	Customize the label text (e.g., “Average is”)

Computed Values

Computed values (also called computed functions or computed items) are dynamic content items that calculate values using JavaScript code. Unlike static content items like text or images, computed values are generated automatically based on answers from participants or other data in your poll or assessment. They are computed/collected rather than created as static pieces of content. Computed values are items associated with modules that calculate a value using custom JavaScript code. They enable you to:

Perform calculations on participant answers
Create derived metrics from multiple data sources
Generate dynamic values that update as participants respond

Types of Computed Values

There are several types of computed values used in different contexts:

Presenter computed functions: Set via presenter cards’ toolbars (shared across cards). Values are calculated on the server during polls, debounced to run in batches rather than after each answer. Available in the poll/computedResults getter.
Public computed functions: Presenter computed functions flagged as public in the editor dialog, making them accessible to participants.
Student computed functions: Defined via student perspective cards’ toolbars. Calculated on the client side. Available in the poll/computedValues getter.
Report computed functions: Live in courseware modules and are used by report cards.

Using Computed Values in Graphs

Computed values can be used as inputs for many graph types, including:

When configuring a graph, look for computed values in the input selector - they appear with an “fx” icon and are labeled as “Computed:variableName”.

Data Bins

Data bins are dynamic content items that hold and aggregate data from multiple projects or polls. Unlike static content items, data bins store computed results that are derived from their associated data inputs and update automatically. They are computed/collected rather than created as static pieces of content, facilitating real-time insights and analytics across your organization. Data bins allow you to:

Aggregate results from multiple polls or projects
Store computed results that update automatically
Share aggregated data across different visualizations and dashboards
Create organization-wide analytics and reporting

Key Concepts

Data Bin: A unique container defined by administrators to store a single aggregated result at any given time.
Inputs Collection: A nested collection within each data bin that stores data inputs from various projects or polls.
Computed Function: A JavaScript function defined per data bin that processes data from the inputs collection to compute the bin’s result.
Evaluation: Automatic computation of data bin results triggered by changes in inputs, with optional manual evaluation.

Using Data Bins in Graphs

Data bins can be used as inputs for many graph types, including:

When configuring a graph, look for data bins in the input selector - they appear with an inventory icon and are labeled as “Databin:labelName”.

Creating and Managing Data Bins

Data bins are created and managed by administrators in the Organization Admin Panel:

Navigate to the Organization Admin Panel
Select the Data Bins section
Click “New Data Bin” to create one
Enter a descriptive label and define the computed function
Save to create the data bin

Data bins automatically recompute their results whenever an input in the collection changes. Manual recomputation can also be performed during editing or previewing.
