The default Horizontal / Vertical Scale of a LabTutor Data Panel can be changed in two different ways within LabAuthor:
- In the Authoring View, right-click the LabTutor Data Panel, and click 'Activate'
- Adjust the Scale as desired using the Student scaling controls
- Go to Help | Preview in Browser to open your Experiment in Internet Explorer
- Adjust the Scale as desired
Then save and upload your Experiment to your LabTutor Server to apply the new default scale. Note that Students will still be able to adjust the scale (unless you also disable their ability to do so in the Panel Properties).
