breeze plot would compile inside eclipse

[Bruce Ho]

I tried running the simple breeze plot sample code in a scala file inside eclipse, and it won't compile. on the line

import breeze.plot._

    val f = Figure()

    val p : Plot = f.subplot(0)

    

    val x = linspace(0.0,1.0)

    p += plot(x, x :^ 2.0, '.')

for the last line, I get compilation error: - too many arguments for method plot: ()Unit

However, I move the exact same code into scala interpreter inside eclipse, it runs fine. Any one knows what's the problem?
