Subplots not appearing

[ashleightrinh]

I have multiple matrices I want to plot in a column. Despite using similar code as in the subplots section it does not appear when I combine them, as shown:

p1 = plot(t, g1);
p2 = plot(t, g2);
p3 = plot(t, g3);
[p1, p2, p3]

After typing that into the terminal this is the result I get is

3-element Array{Plots.Plot{Plots.PlotlyJSBackend},1}:
 Plot{Plots.PlotlyJSBackend() n=6}
 Plot{Plots.PlotlyJSBackend() n=6}
 Plot{Plots.PlotlyJSBackend() n=6}

and no plot appears.

I am using Plots with the plotlyjs() backend.

Hi @ashleightrinh thanks for coming here!

The issue here is somewhat subtle: the [p1, p2, p3] syntax only works when you use PlotlyJS.jl directly. In order to create subplots using Plots.jl you need to tap into the layout functionality offered by Plots.jl (documentation here).

Hopefully that helps!

Hi @sglyon thank you for responding so promptly!

I've tried it again using PlotlyJS.jl and now I do get a plot window opening but for some reason all the plots are empty.

Previously when I tried the layout method offered by Plots.jl it got really complicated since each of my individual data sets (g1, g2, etc.) has 6 lines to plot but they all get plotted in separate subplots rather than each set of data in one subplot each.

Thank you for the help!

Hmm that's odd. Could you please post a sample of the t and g1 variables so I can try it out myself?

If the data are sensitive you could just create a random data set of the same type as the original objects.

Hi, so the code is quite long so I will attach it as a word document and can be copied and pasted.
It's a function so I don't know how to extract just t and g1.

[ashleightrinh]

Sorry, I thought close and comment meant close the window.

[sglyon]

No problem.

I don't have word on my computer.

I should be able to tell everything that I need just from the types of t and g1

Could you instead just post the types of these two variables. You can use the typeof function to get that info

[ashleightrinh]

Ok, so g1 is an Array{Float64,2} and t is an Array{StepRangeLen{Float64,Base.TwicePrecision{Float64},Base.TwicePrecision{Float64}},1}.

Hey @ashleightrinh thank you for that.

It turns out this was an issue within PlotlyJS that I've just fixed with the previous commit.

If you do Pkg.checkout("PlotlyJS") and then try your plotting code again it should work now.

Today I will tag a new release with METADATA.jl. This means if you wait a few hours you can do Pkg.update() instead and your example will work with the released version of this package.

I'll try to remember to post here when METADATA is updated.

The METADATA PR has been merged: JuliaLang/METADATA.jl#10250 (comment)

You can now just do Pkg.update() to get the version of PlotlyJS.jl where you could should work. If it doesn't work after updating please respond here!
