| 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 visible data in the current layer, including a histogram. |

Your Mars Retrieval icon now acts as a proxy to the data it has retrieved - you can right-click and Visualise it for instance.. The data for this icon is cached as long as the title is green, and will not be re-retrieved until you either restart Metview or edit or rename the icon.
Icon management: rename this icon to "get_r". Now make a duplicate of the icon and rename that one to "get_t". Edit this new one, change Change Param to T, save the icon and now directly right-click and Visualise it. The Execute step is performed automatically for you.
