Customize and Manage the Visualization

Edit the Event Data

To edit the event data, for example to add events or correct a scoring error, do the following:

1. If you have only one observation visualized, click the Open Current Observation button on the toolbar. If you visualized more observations, choose Observe > Observation > Open.
2. Edit the data as explained in Correct Event Log Errors Manually in Carry Out an Observation. You can only edit observational data, not external data or audio.
3. To return to the visualization, click the Visualize Current Observation button on the toolbar. Alternatively choose Analyze > Visualize.

Zoom In/Out

To zoom the plots relative to time, click the Zoom In or Zoom Out button on the toolbar. Click the plot multiple times to reach the desired time zoom level. Every time you click, the plot is enlarged or reduced by a factor of 2. To zoom in or out relative to amplitude (only for external data and audio), click the Y-axis with one of the zoom buttons.

To return to the normal mouse pointer, click the mouse pointer on the toolbar.

To set a specific time span, choose View Settings > Time Span and set the desired length of the X-axis.

Change the Time Format

To change the time format, for example from absolute to relative, or to change the number of decimals, do the following:

1. Choose Setup > Project Settings > Time Formats in the left pane.
2. Select the preferred options. See Time Formats.

Show and Hide Events

Events are shown according to the hierarchical structure in the coding scheme. Behavior groups are listed in the left-most column of a plot. By default, all events are shown.

To collapse a behavior group, a behavior, or modifiers attached to a behavior, click the – sign in front of the behavior group name, behavior name, or modifier name. To expand again, click the + sign.

To remove behaviors from a plot, create a data profile (see Select Data for Analysis) and re-create an event plot.

Sort Plots

To change the order in which plots are displayed, move them up and down in the visualization.

1. Click the header (left-most cell) of the plot you want to move. The border of the plot is highlighted in blue.
2. Drag the plot to the desired position. Release the mouse button to confirm the position.

Show and Hide Plots, Video, Audio, and Comments

Choose which plots to display with View Settings on the far-right side of the toolbar.

• Event Plots — Choose View Settings > Events or double-click the header (the left-most cell of the plot). Choose which event logs to display.
• Video — Choose View Settings and select or deselect Videos.
• Audio — Choose View Settings and select or deselect Show Audio.
• Comments — Choose View Settings and select or deselect Show Comments.

Change the Colors

To change the color of events or imported data, click the colored square in front of the appropriate event or data stream and choose a new color.

Customize the Audio Plot

To show or hide specific audio streams, choose View Settings > Show Audio and choose the audio streams. To display data points in the plot, choose View Settings > Data Points. To change the color of the audio plot, click the colored square in front of the file name or the audio waveform and choose another color.

Export Visualization as Picture

To create a screenshot of the visualization:

1. Make sure the part of the visualization you want to export is visible on your screen.
2. Click the camera button on the component toolbar.
3. Choose the location and picture format.
4. Accept the default file name or enter another one and click OK.

You can also copy the visualization and paste it into another program.

Export the Visualization as Table

1. Click the Export Visualization Data button on the component toolbar.
2. Choose the file format (Excel or text).
3. Choose the observations to export.
4. Select the destination folder and enter the export file name, and click OK.

Notes:

• If you selected data before creating the visualization, only the time intervals specified in the Data Profiles are exported. See Export Observational Data.
• It is not possible to export the event plot of multiple observations with the Export Visualization Data option if the observations contain external data. Instead, choose File > Export > Observational Data. See Export Observational Data.
• It is not possible to edit an event plot if the project is read-only, for example if the project is stored on a CD/DVD, or if the project is already open in another Observer XT window (that is, two or more instances of The Observer XT are active at the same time and one shows the same event plot).
