In the Line chart task learners are able to create or modify line charts. You can pre-populate the chart with as much or as little data as you’d like. For automarking you can specify what points you expect where or you can leave it completely open.

The Line chart task is useful for helping learners to practice graphing, correcting incorrect points on a graph, or doing the heavy-lifting of some point-plotting for learners leaving them to just complete the graph or making predictions. Let’s take a look at a few examples.

In this example we give learners a partially completed graph, then ask them to predict the shape of the graph after 150s.

In this next example we ask learners to identify the mistakes in the graph and correct them.

In the example below we leave all the points on the chart at zero for learners to make their own graph.

The Line chart task has some overlap with the Plotting task, in that you could really use either when you want learners to create their own line graph. However, we find that although it’s a tad more complex for learners to use, the Plotting task is a little more flexible in how you can let learners plot the points. So if your learners are used to plotting graphs, we’d typically advise using the Plotting task instead. Choose the Line chart task when you need simplicity.

All tasks load with an example task to give an idea of what each field is for. To add your own task details, you can type over the existing content in the fields or select Clear task content, to start completely fresh.

This task has the standard fields/options that all tasks have.

At the top:

And at the bottom:

In between the top and bottom standard fields we have the following areas and fields.

Here is where you set the graph labels and set the points that learners can drag.

You can add a chart title by inserting it in the Name field.

Name: Adds a graph title.

For each point in the chart you can set these fields:

Select +Add to add more points to the chart.

Select the delete icon beside a point to remove it.

If you want the task to be automarked, you can set drag each point in the chart to its correct value.

If there are other correct answers, use the + to add alternative answers.

As seen in the examples, you can also choose to not set a correct answer. In which case, the task will not be automarked and the task will be allocated the complete/incomplete with feedback marking template to allow facilitators to manually mark the task (if desired).

You can also specify additional options:

Authors can set additional options that can be available for learners when interacting with points:

People using only a keyboard and/or using a screen reader can interact with our graphing tasks.

People using only a keyboard can tab to the menu and navigate the menu items using arrow keys. Options in the menu can be selected with either Spacebar or Enter.

Tab will take them to the graph plane where they can navigate the grid using arrow keys. Points can be plotted with Spacebar or Enter. Pressing Shift-Tab will take the learner back to the menu to select further options.

Note: at this stage, the label tool is unavailable for keyboard-only users.

People using screen readers can use the same keyboard navigation described above.

When navigating to the graph, the screen reader will describe the content of the graph including the axis values and any background shapes.

When navigating to the menu, the screen reader notifies people of the keyboard controls to interact with the menu. All menu options are announced as they arrow through the options.

When tabbing to the graph plane, the screen reader notifies people of the keyboard controls to interact with the graph plane. As they navigate around the graph the coordinate locations are announced and as they plot points they are notified of the plotted point and its coordinate.

When people press Shift-Tab to go back to the beginning of the graph, they are notified of all points or shapes plotted.
