How to configure a Grid Overlay's 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. Depending on the calculation, the range of results, the theme of the calculation and the intended audience for the results, it is often desirable or even required to configure the legend so that the the full range of data can be easily interpreted visually.
- In the left panel of the editor, select the Grid Overlay to configure
- In the right panel, switch to the "Legend" tab
- Activate the "Custom Legend" option
- Ensure the right amount of entries exist:
If the legend should consist of more entries than currently available, click on "Add" at the bottom of the right panel until the right number of entries exist. (New entries are added with a value of 0).
If the legend should consist of fewer entries than currently listed, select one or more entries to remove and click on "Remove" at the bottom of the right panel. - Configure each individual entry in the entry:
To configure the name of the entry, in the top input field of the entry enter the appropriate name/description
To configure the color of the entry, click on the color dropdown and use the color picker to select an appropriate color
To configure the value for which the color should be displayed, enter the appropriate numerical value in the value input field

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 of lowest entry respectively.
- 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.
