I have a problem to display elevation data with pseudocolours. The channel 1 is from -3.40282e+38 to 149.717 . A colleague used 1.7. and it looks like it should (from blue to Red) when I use QGis 1.8 the complete raster is red with an unreasonable classified legend with four colours (three with minus values, one with maximum value red)
How do I do this?
