Figure dimensions are the way you organize your experiment data into columns, rows, and tables. (For a histogram overlay, "rows" will be the overlaid dimension.)

Think of dimensions as variables measured in your experiment (Conditions, Dosages, Timepoints etc.)

When a dimension panel is red (red), that means that it needs to be annotated.

Click on the dimension buttons to open and close the panels. The buttons are orange (orange) when open and blue (blue) when closed.

When a dimension panel is open, it displays any data that has been annotated.

Click and drag the dimension panels onto the green underlying box (appears when you drag) to change their order. To change the order within a dimension panel, use the Layout Placeholders tab to reorder the labels in your Illustration.

If a dimension panel is open and has no data, the illustration can't be drawn. Click "Edit" to annotate the dimension or close the dimension button.

Unfortunately, you cannot edit a dimension name.
