| Magnifier |
| Toggles the magnifier tool on and off. Unlike Zoom, this is a purely graphical enlargement of the plot. It is used mainly to inspect small text such as contour labels. The magnifying glass can be moved and resized using the mouse, and the magnification scale on its left-hand side can also be adjusted. |
| Cursor data |
| Toolbar toggles a panel which follows the mouse cursor. Click with the left mouse button to 'dock' or 'undock' this floating panel. It provides information about the data point closest to the mouse cursor. |
| Animation |
| The Frames tab to the right of the plot shows the set of fields contained in the GRIB file. You can move between fields by clicking within this tab, by using the animation control buttons or by using the cursor keys. Note that each plot is computed and cached only when you select a field. |
| Layer metadata |
| Select the Data tab in the right-hand panel. This reveals a page of meta-data for the current layer, including a histogram. |
