Customize the Event Log Window

Choose the Time Format

  • Choose View Settings > Show Window > Time Formats. Hovering over the Time column displays a tooltip showing the time format.

Show or Hide Columns

By default, all elements defined in the coding scheme appear in the event log, along with a Comment column.

  1. Right-click one of the column headers of the event log.
  2. Select or deselect the category you want to show or hide.

If you hide a column in the Event Log, you cannot score those elements anymore. If you click the tab of that element in the Codes window, the column reappears in the event log and you can score the element again.

The Data and Audio Visualization Window

The Data and Audio Visualization window shows the data that you have scored in a Time-Event Plot. The window displays event plots for each subject with colored bars for state events, narrow vertical bars for point events, and colored dots for Instantaneous Sampling data. If you co-acquire data such as FaceReader or Biopac data, a plot for each data stream is added to the window after you stop the observation.

Data selection does not affect your plot. If you do not want to see the data of all subjects, go to View Settings > Event Visualization > Show Time-Event Plot and select the subjects of your choice.

See the Visualize Data chapter to:

  • Change the time format
  • Show and hide events
  • Sort plots within a visualization
  • Change the colors
  • Customize the audio plot
