Point plots

Output the array of complex values as a mesh of points in the plane.

dots(rand(Complex{Float64},100),color=color(0,100,155),size=0.7)

Output the matrix entries as a mesh of points in the plane with the color map according to their absolute values. If the absolute value of the entrie is smaller than eps (default value 1.e-6), it is not plot. The entrie M[i,j] is put in position ((j-1)/(min(n1,n2)-1), (n1-i)/(min(n1,n2)-1)).

dots(rand(25,100))
dots(rand(25,100),0.2)

Output the support of polynomial as a mesh of points. Only the exponents of the first 3 variables in the monomials are used. If the polynomial is with n variables, the mesh is in dimension min(n,3).

p = x^2 + y^2-1
