Julia: Plot matrix with Gadfly.jl

gadfly, julia

Solution

Gadfly has a `spy()` function which does the same thing.

using Gadfly
p = eye(5)
p[end, end] = -1
spy(p)

Problem

I'm trying to plot a matrix with Gadfly, like I can do with PyPlot's `matshow`: ``` using PyPlot p = eye(5) p[5,5] = -1 matshow(p) ``` But I took a look at the docs, and found nothing. How can I do it with Gadfly?
