"},{"location":"layers/","title":"Layers","text":"The paint and layout properties for the layers depend on the type of the layer. They are passed as a dict corresponding to the Layer Style Spec.
For example, to set the radius and the color for a circle layer, the paint property looks like this:
paint = {\n \"circle-radius\": 5,\n \"circle-color\": \"yellow\"\n}\n
The value for any layout property, paint property, or filter may also be specified as an expression. For details see Expressions.
For example, if the source of your layer has a color property that contains the color of the feature, you can use the following expression:
paint = {\n \"circle-radius\": 5,\n \"circle-color\": [\"get\", \"color\"]\n}\n
A more complex expression where the color depends on the type property of the layer's source might look like this:
paint={\n \"circle-color\": [\n \"match\",\n [\"get\", \"type\"],\n # darkred if type == \"mid\"\n \"mid\",\n \"darkred\",\n # darkgreen if type == \"major\"\n \"major\",\n \"darkgreen\",\n # else blue\n \"darkblue\",\n ]\n}\n
Filter features of a source according to its magnitude property:
# Only show features where magnitude >= 5\nfilter = [\">=\", [\"get\", \"magnitude\"], 5]\n

"},{"location":"layers/","title":"Layers","text":"The paint and layout properties for the layers depend on the type of the layer. They are passed as a dict corresponding to the Layer Style Spec.
For example, to set the radius and the color for a circle layer, the paint property looks like this:
paint = {\n \"circle-radius\": 5,\n \"circle-color\": \"yellow\"\n}\n
The value for any layout property, paint property, or filter may also be specified as an expression. For details see Expressions.
For example, if the source of your layer has a color property that contains the color of the feature, you can use the following expression:
paint = {\n \"circle-radius\": 5,\n \"circle-color\": [\"get\", \"color\"]\n}\n
A more complex expression where the color depends on the type property of the layer's source might look like this:
paint={\n \"circle-color\": [\n \"match\",\n [\"get\", \"type\"],\n # darkred if type == \"mid\"\n \"mid\",\n \"darkred\",\n # darkgreen if type == \"major\"\n \"major\",\n \"darkgreen\",\n # else blue\n \"darkblue\",\n ]\n}\n
Filter features of a source according to its magnitude property:
# Only show features where magnitude >= 5\nfilter = [\">=\", [\"get\", \"magnitude\"], 5]\n
