mkdir juliastuff
cd julia stuff
tar -xvf julia-0.4.6-linux-x86_64.tar.gz
In below command replace xyz by the full path to the bin directory of julia
export PATH=xyz:$PATH
module load git_1.8.2.3

  • Plotting with Gadfly *

At the Julia prompt
(In below command replace abc with your userid)
rm /usr/lusers/abc/.julia/lib/v0.4/Compose.ji
Restart Julia
At the Julia prompt:
Below error is due to missing xdg-open on Hyak. It is minor error.
myplot=plot(sin, cos, 0, 25)
Error showing value of type Gadfly.Plot:

  • Plotting with Python Matplotlib PyPlot *

At the julia prompt:
using PyPlot
x = linspace(0,2*pi,1000); y = sin(3*x + 4*cos(2*x))
plot(x, y, color="red", linewidth=2.0, linestyle="--")
ERROR: ArgumentError: haskey of NULL PyObject
(Above is a Julia bug in calling Python matplotlib properly)
