An enumeration of label options that control label attributes
Sets the offset of the label in characters
Sets the font of the label. The string specifies the font type (e.g. “Arial”) and the number specifies the size (the units are terminal dependent, but are often points)
Sets the color of the label text. The passed string can be a color name (e.g. “black” works), or an HTML color specifier (e.g. “#FFFFFF” is white)
Rotates the label by a certain number of degrees
Sets the horizontal alignment of the label text (default is left alignment). See AlignType.
Sets a marker for the label. By default no marker is drawn. The valid characters are as follows:
.- dot+- plusx- cross*- stars- empty squareS- filled squareo- empty circleO- filled circlet- empty triangleT- filled triangled- empty del (upside down triangle)D- filled del (upside down triangle)r- empty rhombusR- filled rhombus
Sets the color of the marker. The passed string can be a color name (e.g. “black” works), or an HTML color specifier (e.g. “#FFFFFF” is white)
Sets the size of the marker. The size acts as a multiplier, with 1.0 being the default.
