Updating labels in plot! about plots.jl HOT 19 CLOSED

It would also be nice if you could only set the labels without plotting anything extra, for example

p = plot(rand(10))
plot!(;xlabel="label")

from plots.jl.

Yeah this should be possible with most backends. I see you're using pyplot, so I'll handle that first.

I'll also add shorthands 'xlabel!()', etc. I should be able to do this today.

I'm using PyPlot because I'm having some troubles with the other backends in IJulia.

For example:

Same with Immerse and Gadfly.

from plots.jl.

I'm a little confused what you're trying to do. x_mod and y_mod are not valid arguments in Plots, so I wouldn't expect this to flow through to the backends at all. Also what is matstats? Let me know how you'd like to call this, and I can either tell you the right way, or add support for it.

from plots.jl.

Sorry, I understand your confusion, I should have explained better. I am writing a package where the resulting data is a bit messy to extract from the type. To facilitate plotting of the results I therefore extend the plot function in Plots.jl with another function that take the types in my package (matstat is one of those types). This function then extracts the needed data from the type and then finally calls the Plots.jl plot-function and return that plot object

However, the problem has nothing to do with this, it is just that with certain backends like Immerse, Gadfly, Winston I get no output in IJulia.

An example which does not contain any of my own code:

from plots.jl.

Using for example Gadfly directly works.

from plots.jl.

Ah I see, so it's just not displaying in IJulia. Ok I need to look into that... I don't actually use IJulia at all, but I know others do, so I want that to work as expected.

from plots.jl.

Just installed IJulia, so I'll investigate further. However, does it work if you do:

using Plots
gadfly!()
plot(rand(10))
display(currentPlot())

from plots.jl.

Cool! That works beautifully for Gadfly and Immerse (Immerse opens a new window but I guess this is to expect since it has the GUI functionality).

For Winston (works with using Winston):

LoadError: MethodError: `display` has no method matching display(::Gtk.GtkCanvas, ::Winston.FramedPlot)
Closest candidates are:
  display(!Matched::AbstractString, ::Any)
  display(!Matched::TextDisplay, ::Any)
  display(!Matched::MIME{mime}, ::Any)
  ...

from plots.jl.

Ok thanks. I'll look into Winston, but I suspect that IJulia calls a
specific "writemime" method to show its results, and my display method is
only getting called from the REPL. It should be a relatively easy fix, as
soon as I figure out the specific problem.

By the way, this works on the development branch, and I'll push it to master once I finish with a display/writemime re-write.

using Plots
plot(rand(10))
plot!(title="title", ylabel="ylabel")
xlabel!("xlabel")   # shorthand for plot!(xlabel="xlabel")

from plots.jl.

Both the original labels/title request, and the IJulia display issues should all be fixed now on latest master. Please try it out.

from plots.jl.

Works great! Thanks!

from plots.jl.

Cool! If there's anything that's not easy or intuitive, please let me
know. I want this to be the kind of package that "just works" no matter
what you throw at it.

One thing, for Gadfly this works great:

For Pyplot I get two outputs, one that is above the Out:

Winston works.

Unicodeplots workish (maybe this is a limitation with the backend):

from plots.jl.

Thanks... I'll look into PyPlot's double-display. As for UnicodePlots, that's more of a REPL plotting tool... I'm actually surprised it does anything even remotely good in IJulia!

from plots.jl.

Also one additional comment... unless you need the plot reference p somewhere later in your code, it's unnecessary. Instead of

pyplot!()
p = plot(rand(10))
plot!(p, rand(10))

you can do:

pyplot!()
plot(rand(10))
plot!(rand(10))

Plots keeps track of the "current plot" for you, and when you leave it out it will automatically update the current plot.

from plots.jl.

I pushed to master. The pyplot double-show issue is still there, and is not an immediately easy solution. The pyplot code is a little hacky to get it to work in IJulia, and the figure seems to be displayed at various stages of the building process, and not after the plot method returns. It works fine at the REPL, so I need to pour through Steven's code a little more to understand what he's doing for IJulia.

closing for more specific issue #29
