Visualize Your Data in a Chart

Aim

To visualize your data in a Pie Chart, Box Plot, Bar Chart, Circumplex Model or Line Chart.

Prerequisites

• Your FaceReader license includes the Project Analysis Module.
• Your project includes one or more video or camera analyses.

Procedure

1. Open the Project Analysis section and click either Pie chart, Box Plot, Bar Chart, Circumplex Model or Line Chart.
2. Select the data you want to include in your analysis. See Data Selection for more information. Click OK when you are ready. FaceReader will show the chart.

Click on the colored circles below the chart to exclude or re-include the corresponding data from/into the chart.

Each chart has a toolbar with the following information/icons:

• Edit Selection — Click this button to open the Data selection window and change your selection. Click OK when you are ready.
• Adjust Caption — Click this button to change or reset the chart's caption.
• Display Data — Click this button to view a table containing the data on which the chart is based, per participant and aggregated over participants. The table also shows the number of frames in the participant video or camera stream that was taken into account. If the chart is a Line chart or Circumplex Model the table shows the data per sample point aggregated over participants.

  The table in the example below comes from the 'FaceReader sample project - Two stimuli' and shows the mean intensities of the facial expressions Neutral and Happy per test participant and (in the last row) the mean intensities over test participants during the time that the test participants watched the 'Twins eating' stimulus.

  Click the Save button to save the table, either in *.txt format or in *.xlsx format.
