Trying to plot a Matrix with a single nonzero element in Gadfly using
*using Gadflya = zeros(Float64, 10,10);a[5,5] = 1;spy(a)* The result is shown in the attached figure. How can I convince Gadfly to show me also the zero values, in order to see the whole array, not just one element? To see what I mean, replace *zeros(Float64, 10,10) *with *rand(10,10) *for instance.
