The Read-only Data panel is used for displaying LabChart data files (.adicht).
The Read-only Data panel can be found by selecting PANELS from the footer, then selecting PowerLab:
Drag and drop the Read-only Data panel onto the lesson page. Just like any other panel, a blue line will indicate where your panel will line up. You can easily rearrange panels if you’re not happy with the layout.
To add example data, select the panel and select Edit (or double-click on the panel), then select Add Data, or simply drag and drop your desired LabChart Data file (.adicht) onto the lesson page. You can also download data files from existing Read-only Data panels by selecting the download button in the footer with the panel in Edit mode.
