Try a 2D texture (replicate your 1 D texture to create it)...

Some hardware has limitations in the aspect ratio of the supported 
textures, but texture with dimensions like 256x32 should fit most 
hardware. (or 128x16 etc if the smaller resolution is ok.
Actually even smaller resolution like 32x4 might be ok if the 
texture interpolation results are ok for your color scale)
