Layers > Vector layer

This Tab provides controls to classify, display and label vector entities.

Style: selection between various thematic classification methods. The program uses this method to classify the values of the selected classification field (or data column) into categories. The following methods are available:

•	Single: displays every entity in the same way, it creates one single class

•	Unique: every unique values of the data field constructs a thematic class

•	Equal: the range between the minimum and maximum values of the data field is divide into Classes number of equal parts

•	Interval: the range between the minimum and maximum values is divided into interval size parts

•	Deviation: the range are defined by the average - 3 times standard deviation and average + 3 times standard deviation, the range is divided into Classes number of equal parts

•	Quantile: the class boundaries will be created that each class contains (approximately) equal number of entities

•	Modulo: the classes are created by the remainder division of the data values (from zero to classes-1)

Classify: selection of the classification field (data column) to generate the thematic classes

Classes: number of thematic classes. In case of Interval method it defines the range of one class.

Palette: classifier chooses colors from this color palette.

Transparency: defines the opacity of the vector elements. 0% means the elements are fully filled, 100% means the elements are fully transparent.

Filter geometry type: the program displays all or only the selected type of geometry on the map. It is useful the filter Dxf or Mif sources.

Label #1: defines the first data field (data column) to display on the map.

Label #2: defines the second data field (data column) to display on the map. If the length of the composite label is larger than 10 characters it will be displayed in two rows.

Label size: defines the size of the label in points (10 points are 3.528 mm). This is the screen/printer resolution independent definition of the label size.

Label color: the color of the labels can be selected.

Label effect: provides various labeling effects:

•	none: simple labeling

•	frame: labels will appear on a filled rectangle

•	halo: labels has a thin contour

•	bold: labels use bold face

•	bold+frame: combination of frame and bold, bold labels appear on filled rectangles

Label background color: defines the color of the rectangle or contour for labeling.

Label display scale: controls the maximum scale number (smallest scale) to display the labels.

Outline display scale: defines the maximum scale number (smallest scale) to display the contour lines of a polygon.
