Detailed Description

MeshViz Class to build a linear auto value legend.

Class to build a linear value legend. The space between boxes is null and their width (or their height) is proportional to the difference between two consecutive values. The legend is composed of one column (or one row depending on the orientation of the legend). There are three possible representations:

  • The values displayed are calculated from a data mapping object or an isovalue list object.
  • The values displayed are calculated as with a linear axis. They are linearly distributed depending on the min and the max of the values of the data mapping object or the isovalue list object.
  • Only the min and the max of the values of the data mapping object or the isovalue list object are displayed. The fields incrementType, numColumns, and boxRatio are not used for this representation.
