General Usage

Trying to write a plot in hdf5 format yields the following error:

using Plots, HDF5

julia> hdf5()
Plots.HDF5Backend()

julia> p=plot(1:10, 1:10);

julia> Plots.hdf5plot_write(p, "plotsave.hdf5")

The syntax follows the documentation exactly (I think).

Is this a bug or am I making a mistake?

Unfortunately, it appears to be a newly created bug: struct Attr was created on January 28th, and my implementation of the HDF5 writer does not support the new object hierarchy.

I will see what I can do. I am not exactly certain when I will have the time to create a fix, though.

Thank you.

The solution was just merged into the master stream:
→ Fix broken hdf5 "backend". by ma-laforge · Pull Request #2492 · JuliaPlots/Plots.jl · GitHub

You should be able to temporarily check out the “dev” version, or wait until the next release of Plots.jl.

Thanks again!
