How can I superimpose 1D streamline (color) on 2D grayscale image?

Hi,
I have a 2D grayscale image (128x128 double) and a 1D streamline with color (400x1 double). I can overlay the streamline color on the 2D grayscale image, but the streamline color would change to grayscale too.
I check that function imoverlay can do this but it requires both inputs in 2D. Anyone can help me to superimpose the 1D streamline color on 2D grayscale image by having different colormap?
Thanks.

You forgot to attach/insert the images. I'll check back tomorrow. In the meantime, see http://blogs.mathworks.com/steve/2009/02/18/image-overlay-using-transparency/
