The line graph in the project report allows you to very quickly visualize which tasks in your study were the most positive and negative relative to one another.
Along the x-axis on the bottom you see numbers which represent each of the tasks that you defined when you setup your study. Along the y-axis on the side you will see the overall emotion of all participants aggregated for each task, which is a measure of positive vs. negative emotion.
Vempathy automatically selects the most negative task so that you can drill down further with the insights that we uncover below the graph. These same insights are available for all tasks and can be quickly accessed by clicking anywhere within the graph.
