Creating a New Style
Here’s how to create a new style:
Click the Options icon to the right of your layer name in the Legend.
Click Edit Style in the menu. The Style Editor opens.
Click the Create New button at the bottom of the Style Editor.
Enter a name for your style in the Create Style window. The style name does not support special characters. It supports upper and lower case letters, spaces and underscores.
Do not change the default style Type. It is Thematic.
Click the OK button. Your new style name appears in the Style drop-down menu. You can now format the visual attributes of your new style.
