Authors can add a prompt, set the graph type(s), grid coordinates, the axis min/max and labels, change the line settings as well as add pre-plotted points. Students can choose the graph type from the dropdown, add responses by clicking in the graph, moving points around and removing responses. This is a machine scored interaction. It can also be used to create a non-scorable stimulus.

See Author Test Items for general instruction on item creation.

Graphing Settings

Non-square grids are supported  on the Graphing Interaction. 

  • Type: Choose from Line Graph, Scatter Plot, Polygon Graph, Quadratic, Exponential, and Absolute Value. 
  • Label: Enter a label to appear above the grid
  • Max Coordinates: indicate the maximum number of points that may be plotted on the graph.
  • Show Origin: 
  • Alt Text: Any text here will be read by screen readers.
  • Height/Width: Enter the dimensions of the graph, keeping in mind the size of the testing devices.



X-Axis and Y-Axis


Sample setup

Line Settings

  • Segment Mode
  • Connect Static: If you want the student to create a line to that static mark then you click connect static. When they click to respond it will make a line to connect.



Score Settings

If scoring is required, enter a value in Max Points and be sure to plot the answer in the Correct Response Center. 




Sample Point Graph Interactions


Add Labels to Graph Types

Authors can add labels to graph types so the dropdown can display other terms or languages. The ‘Type Labels’ field appears on the Editor tab dynamically with the selected types. When a single type is selected the section will be hidden. 


Display Origin Other than 0,0

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.

The sample on the left has two different origins; the sample on the right has the same value.

Quadratic Initial State Option

Authors can set an initial state of a quadratic graph that students can then drag in order to set their response. Initial state will always use coordinates (0,0) and (1,1). Students can reset their response to the original state by using the Reset button.
