Add another layer to a legend in Surfer

By default, the legend for a map in Surfer contains entries for each map layer in the project that supports legends (post, classed post, vector, drillhole, contour, and base layers with symbology) at the time the legend was added. If a supported layer is added later, it can easily be added to your existing legend.

To add a layer to your legend in Surfer:

1. Select your legend.
2. Click on the Layers tab in the Properties window.
3. In the Layers in Legend section, click the Edit List button in the Edit layer list field.
4. In the Layers for Legend dialog, choose the layer you wish to add to the legend from the Available layers to Selected list by using the button.
5. Click OK to close the dialog and add that layer to the legend.

Now that you have multiple layers in the legend, you can display a title for each section displaying which layer the legend pertains to (in the General section check the box next to Show layer name).

You can edit the layer properties for each section by selecting the layer from the Layers to edit field in the Layers in Legend section and then editing the properties for that layer in the section below.

Golden Nugget : You can add Contour layers (showing major/minor line styles and labels) and Drillhole layers directly to multi-layer map legends, even without symbology applied!
