The Layers tab in the sidebar of the Display Window allows for some sophisticated interactive editing of the current plot.
Layer order and transparency

Inline editing of visual definition icons
The image on the right shows a Metview Display Window with two data fields plotted, each with its own Contouring icon, plus a custom Text Plotting icon for the title.
We'll look at the Display Level and the View Level sections in a moment, but for now look at the Plot Level section. This contains all the elements of the plot that can either be re-ordered or edited.
Layer t1000 comes from a MARS Retrieval icon called t1000. When the layer tree is expanded we see the data icon plus the visdef icon (shade) that has been applied to it. If we want to change the contouring parameters for this layer, we can edit the shade icon directly in the plot by double-clicking on it (or right-click | Edit in plot). The icon editor appears; when you click Ok, the changes are applied immediately to the plot. Your changes will not be saved back to the original visdef icon until you choose Save to disk from the context menu for that visdef. From the context menu you can also remove the visdef from that data layer.
