public class PoLabel
extends PoChart

Class to build a label field. Builds a 2D label field on 1D mesh (PoIrregularMesh1D or PoRegularMesh1D). The abscissas of the labels are given by the geometry of the current mesh 1D, and the ordinates are given by one of the value-set of the current mesh 1D specified by the field yValuesIndex. Names attached to each label are given by one of the string-set of the current mesh 1D specified by the field stringsIndex.

The fields position, threshold and offset allows the user to set the label position and the field valueType set the values to display as labels. This class also takes into account of the current mesh 1D hints (PoMesh1DHints), and the current mesh 1D filter (PoMesh1DFilter) to filter the geometry of the current mesh 1D. The current label hints (PoLabelHints) is used to specify the appearance of labels. If the offset is different from null and, if the field isLabelLineVisible of the current label hints is set to true then, a line representing the offset is drawn. All labels depend on the current miscellaneous text attributes which defines the font names, line length and so on (PoMiscTextAttr). All numerical values depend on the current numerical display format (PoNumericDisplayFormat).

The interpretation of colorBinding is the following :

INHERITED: All labels are colored with the same inherited color.
PER_PART, PER_VERTEX: A color is used for each label.

File format/default:

PoLabel {

colorBinding	INHERITED
yValuesIndex	-1
colorValuesIndex	1
material	NULL
stringsIndex	0
axis	X
valueType	VALUE
position	VALUE_POS
threshold	0.
offset	0. 0. 0.
fontSize	0.0

- Field Detail
 - stringsIndex
```
public final SoSFInt32 stringsIndex
```
 Defines the index of the set of strings used for the names attached to labels when valueType is equal to NAME. If the field value is negative, no names is attached to labels.
 - axis
```
public final SoSFEnum<PoLabel.AxisType> axis
```
 Defines from which axis the position and type of displayed values computation is done. All values in brackets correspond to the Y-axis.
 - valueType
```
public final SoSFBitMask<PoLabel.ValueTypes> valueType
```
 Defines the type of values displayed by the labels. There are two ways to display the labels :
 - VALUE: The values displayed correspond to the the ordinates (resp. abscissas) of the current mesh 1D geometry.
 - NAME: The values displayed correspond to the names associated to the strings-set specified by the field stringsIndex.
 - position
```
public final SoSFEnum<PoLabel.Positions> position
```
 Defines the position of the labels. There are three ways to define this position :
 - VALUE_POS: The label position is the given by the current mesh geometry.
 - MIDDLE_POS: The abscissas (resp. ordinate) is given by the current mesh geometry and the ordinate (resp. abscissas) is at the middle between the mesh ordinate (reps. abscissas) and a threshold.
 - THRESHOLD_POS: The abscissas (resp. ordinate) is given by the current mesh geometry and the ordinate (resp. abscissas) is the threshold field.
 - threshold
```
public final SoSFFloat threshold
```
 Defines the threshold used to the set position of the label.
 - offset
```
public final SoMFVec3f offset
```
 Defines an offset applied to the label. This offset is combinated with the label position. If the number of offsets is inferior to the number of labels, they are cyclically used.
 - fontSize
```
public final SoSFFloat fontSize
```
 Font size of labels. If this value is less or equal to 0, the font size is fixed at 0.04. This value is a percentage of the current domain (cf PoBase description).
