How to configure a Grid Overlay legend
Grid Overlays can display wide ranges of values for a wide range of use-cases. The results are computed and stored as individual numeric values on a grid spanning the entire Project. Based on the Legend of the Grid Overlay, specific values are visualized with specific colors. Configure the legend to ensure the full range of data is easily interpreted visually.
Editor → Current Situation (Ribbon tab) → Overlays (Ribbon bar) → The Overlay to edit (Left panel) → Legend tab (Right panel)
How to configure a Grid Overlay's legend:

- In the right panel, switch to the "Legend" tab

Notes
- The order of entries is dictated by the values of the entries. While editing the values, the entries may reorder automatically.
- Any value in the Grid Overlay results which exactly matches an entry in the legend, will be displayed with that entry's color.
- Any value higher or lower than the highest or lowest entry in the legend will be displayed with the color of the highest or lowest entry respectively.
- For result types using the INTERPOLATED style, any value in between the values of two entries in the legend will be displayed with the interpolated color of the two closest entries.
- NO_DATA values are automatically visualized as transparent.
- The name of an entry cannot be empty. However, a "space" can be used instead to display a color without a (visible) text.
- The Grid Overlay's legend can be reset to the default by unchecking the "Custom Legend" option. Any customizations to that Grid Overlay's legend are then discarded.
