Create Categories to Assign Overlays

You can assign overlays into different categories so that they can be toggled on or off together using the Category Legend function. Markers, lines, curves, polygons and rectangles can be put into categories.

    • Click the Select button on the vertical toolbar, and choose any supported overlay you want to assign.
    • Expand the Ovelays Panel to the right hand side and select any supported overlay from the list.
