The Bar Chart interaction allows authors to create vertical and horizontal bar charts. Authors can add a prompt, set the grid coordinates, add labels, bars and bar groups. Students can add responses by clicking on a bar and moving it. This is a machine scored interaction. 

See Author Test Items and Choice Interaction for general instruction on item creation.


Create a Bar Chart Interaction

  1. From the Editor tab, select Add Interaction > Charts & Graphs > Bar Chart.
  2. Enter a prompt.
  3. In Grid Settings:
    - Optionally modify the Chart, X and Y labels.
    - Enter the Min and Max values. You can show an origin that is not (0,0). Both origins will show if they are different values on the x and y axis, but only one shows if the value is the same.
    - Change increment if needed.
    - Optionally, change to a horizontal Orientation.
    -Unchecking Show Origin will remove the label on the Min value (initial line).
  4. In the Bars section, use the Add Bar (Plus) icon to add additional bars.
  5. For each bar, provide a Label for each bar, as well as a Start and Correct Value. To include a bar with a fixed value that students will not adjust, select 'Static'; the Correct Value is grayed out as it is not applicable.
  6. For Scoring Settings, enter the value of the item. Partial scoring is not available for this item type.
  7. Click Preview. 
  8. Toggle on 'Show Answers' and confirm it works as expected.
  9. Click Save.
