Of course there is. Here is some code snippet i used some time ago for doing
something similar.
gridx = gridy = 50
c = canvas.canvas()
# ...
pal = []
for i in range(gridy):
pal.append([0, 0.5, i*0.5/gridy, (i+1)*0.5/gridy, i*1.0/gridy])
gp = c.insert(graph.graphxy(height=2, width=0.5, xpos=12.5, ypos=4,
x=graph.axis.linear(parter=None),
y=graph.axis.linear(min=0, max=0.5, density=0.5)))
gp.plot(graph.data.list(pal, xmin=1, xmax=2, ymin=3, ymax=4, color=5),
[graph.style.rect(color.palette.ReverseRainbow)])
