Q:

Adding values on reclassified layers using ArcMap?

I have reclassified the values on the layer I am using, however, I would like to  add extra values. The final values showed in the layer should be in a scale from 0 to 10. That means, in this case, I have to add somehow values for 1, 2, 3, 4 and 10. 
Can someone help me with this ArcMap problem? 

A:

I don't think it is possible to add a value to a unique values rendering for an INTEGER raster when the value does not exist in the raster.
Suggest you explore colormaps that may overcome this issue, search Help file for colormap.
