-| Min data value | The minimum value of the input data to scale against. Good for clipping outliers.  |

 ## Layer positions
 
-In the Azure Maps visual, certain layers are fixed, meaning they are set at a predefined level and cannot be repositioned. Other layers are adjustable, giving users the flexibility to choose from three positioning options: "Above Labels," "Below Labels," or "Below Roads."

-Within each Layer position, the order of layers remains consistent. For instance, the 3D barchart layer always appears above the bubble layer due to its higher layer order, regardless of whether they are placed in "Below Labels" or "Above Labels."

 ## Layer order
 
-The following table outlines the layer order from top to bottom along with their respective layer position types.  Layers marked as "Adjustable" can have their position changed using the Layer position dropdown, as shown in the previous screenshot. Layers marked as "Fixed" do not offer this option.
