Detailed Description

MeshViz 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 :
