How do I fill the area under a curve between two $x$-values using sage plot?
For example, maybe I am using the following code:
plot(x(x-1)(x-2)+1,0,2,fill=True)
but I only want the area under the curve from x = 0.5 to x = 1.5 to be shaded in.
If I'm understanding you correctly, then one way to do this is to take advantage of the fact you can add plots:
sage: f = x*(x-1)*(x-2)+1
sage: p = plot(f, 0.5, 1.5, fill=True) + plot(f, 0, 2)
sage: show(p)
@kcrisman: Sure, we'd simply need to have fillxmin and fillxmax and use those instead. Right now it looks like fill is using xmin and xmax for both purposes. (You could probably achieve the same effect by playing games with the function specifications but that seemed like more work than the above..) That would be a good beginner-level ticket for someone who already knows Python.
