Use: Allows students to make a point-based or bar graph based on a previous data table.
When editing components, some sections of the component are required for the activity to save. These sections are marked with a yellow star.
Graphs are only available if there is an accompanying data table; you cannot add a standalone graph. Each table makes its own graph; if your students need to create two graphs, they should have two separate data tables.
There are two types of graphs in the editor: "Correct Answer" and "Pre-populated Value." Like with the data table, the correct answer is only viewable to instructors; the pre-populated data is viewable to the students and how the graphing area will appear to students in the assignment.
To complete a graph, enter data into the data table that corresponds with the graph you are editing. Select the data for each axis by clicking “Configure _____ Axis.” For more information on using the graphing tool, check out our article about using the data tables and graphs.
While you can only have one graph per table, you can graph multiple sets of data on each table. To add an additional set of data to the vertical component, click “Configure Vertical Axis,” then select “Add Column.” Each column will produce its own graphed line, which is color and bullet coordinated.
Add a curve fit using the “Curve Fits” button. The equation for the curve fit selected, along with the RMSE value, will appear beneath the graph.
Configure ____ Axis: This allows you to select the data for each axis.
Bar Graph: This changes the graph to a bar graph for analysis, allowing text data on the one axis for numeric data on the other axis.
Include the origin: forces the graph to include the origin point in the view.
Autoscale view: recalibrates the autoscale to update for any fits.
