Different plotly behavour across computers

It works for me:

julia> time_vect=[1,2,3]
3-element Array{Int64,1}:
 1
 2
 3

julia> dataMat=[2 2 2;3 3 3;4 4 4]
3×3 Array{Int64,2}:
 2  2  2
 3  3  3
 4  4  4

julia> using Plots

julia> plotly()
[ Info: For saving to png with the Plotly backend ORCA has to be installed.
Plots.PlotlyBackend()

julia> plot(time_vect, dataMat, hover = time_vect, layout = (3,1), link=:x)

gives:
newplot

What you see above is a MWE (minimal working example), because others can just copy&paste the code to try and find issues.

Now whats needed next is your MNWE (minimal non working example). There is probably something wrong in your data, which results in the error.
