I am trying to install and run `julia 0.6.4` on a cluster at school. (Firstly I had to specify package directory away from my home folder in `\scratch` to accomodate the 5GB.) Then I installed `Plots.jl` and `Plotly.jl`. However when I try to display or save the plots, I am getting the following errors.

```julia
using Plots
Plots.backend() # Plots.PlotlyBackend()
plt = plot(1:9, cumsum(rand(0:9, 9)))
# Gives
# Error showing value of type Plots.Plot{Plots.PlotlyBackend}:
# ERROR: could not spawn `xdg-open /tmp/juliafDEpPG.html`: no such file or directory (ENOENT)

```

I realize that `xdg-open` is not on the cluster but the file `/tmp/juliafDEpPG.html` is on the cluster. When I copy it to local firefox does not show anything. I guess because the file says: `<script src="file:///scratch/users/rakesh/dotjulia/v0.6/Plots/deps/plotly-latest.min.js"></script>` When I make it point to my local installation of `Plotly` it works. Or when I `savefig(plt, 'name.html')`, it works! **So that’s ok.**

But the following fail

```julia
julia> savefig(plt, "tmp1.png")
ERROR: MethodError: no method matching _show(::IOStream, ::MIME{Symbol("image/png")}, ::Plots.Plot{Plots.PlotlyBackend})
Closest candidates are:
  _show(::IO, ::MIME{Symbol("image/png")}, ::Plots.Plot{Plots.PyPlotBackend}) at /scratch/users/rakesha/dotjulia/v0.6/Plots/src/backends/pyplot.jl:1359
  _show(::IO, ::MIME{Symbol("text/html")}, ::Plots.Plot{Plots.PlotlyBackend}) at /scratch/users/rakesha/dotjulia/v0.6/Plots/src/backends/plotly.jl:932
  _show(::IO, ::MIME{Symbol("image/png")}, ::Plots.Plot{Plots.PlotlyJSBackend}) at /scratch/users/rakesha/dotjulia/v0.6/Plots/src/backends/plotlyjs.jl:105

```

I get similar errors for `.svg`, `.pdf`. How do I fix that?  
Thanks.

It looks like `Plotly.jl` doesn’t support saving figures as a png. You should try another [backend](http://docs.juliaplots.org/latest/backends/) and see if that fixes the problem.

The website [Output · Plots](http://docs.juliaplots.org/latest/output/#savefig-format) seems to say it does support.
