The Index Calculator displays the index using only one color.
The Index Calculator displays the index using only one color. When hovering the mouse on the index view, the correct value is displayed in the lower right corner. The histogram behaves as if only one value was associated to it and has very large min/max values.
If the index formula contains divisions, some index values might get very large. This issue is due to a display issue as the min/max values for the histogram cannot be defined by the user.
As the index is correctly generated it is possible to open it with other software such as Global Mapper and Quantum GIS where it is possible to change the min/max values for the color scale in order to get an appropriate color visualization of the index.
