Another cosmetic, related with #26
If you can split a plot()
function and a embed()
fuction, or something similar.
Can be great if plot()
fit to screen, and embed()
still in the way there is, or maybe a little smaller [ some blogger's blog columns are a little more small than plot wide ].
Hello,
When I run the initial example (with iris) under windows with Julia 0.2 I get:

If I try to move the file by hand, I get the windows error message "can't move the file because it is open by julia-release-readline".
Then if I close julia I can move it and display it.
Any plans to make Gadfly and Compose available as julia packages? I see REQUIRE, so I assume that this is coming soon.
The JSON.jl package was recently updated to change its API a bit (see JuliaIO/JSON.jl#35). In particular:
parse
is now JSON.parse
print_to_json
is now JSON.print
to_json
is now json
I'm hoping to push this to METADATA soon (as version 0.2), so you'll want to update your package.

Hi,
Using a Macbook pro with Mountain Lion OS X, I cannot manage to get Gadly to work. Have I forgotten to install something? I receive the following messages:
julia> using Gadfly
Warning: Possible conflict in library symbol zlibVersion
Warning: Possible conflict in library symbol zlibCompileFlags
Fontconfig error: Cannot load default config file
julia> using Compose
julia> p = plot([sin, cos], 0, 25)
Segmentation fault: 11
logout
[Process completed]
I am new to Julia, so perhaps I am doing some simple mistake?
Edit: I am running Julia Version 0.1.1+111038832.r2e9c.dirty
A couple examples:
spy([1 0; 0 1])
and
xpts = linspace(0,4pi,11)
df = DataFrame({"x" => xpts, "y" => sin(xpts)})
plot(df, {:x => "x", :y => "y"}, Geom.point, Geom.line)
Both lead to this error:

There are no errors installing the package so I'm not sure why this is.
Best,

Would be great to add a writemime(io, ::@MIME("text/html"), p::Plot)
method to render to HTML.
@loladiro and I got a simple version of this working a few days ago in IJulia, and it was pretty cool. (I don't have the code on this machine, though; I can get it tonight from my laptop if need be). Basically, it did three things:
display("text/html", """<script src="http://d3js.org/d3.v3.min.js" charset="utf-8"></script>""")
to load the D3 library from the web. Be sure to catch MethodError
s in case the current displays do not support HTML output. You may want an init_display(d::Display) = ....
to do the same thing for an arbitrary Display
in case the user wants to set up D3 on a new display later.writemime
function to display a Plot
as HTML: just a script
tag with the Javascript, and a div
element with a random ID.This was all that was needed to get clickable, interactive Gadfly plots in IJulia. Some other enhancements:
plot
to call redisplay
on the Plot
automatically, which will queue the plot for display in IJulia. Your draw
function can call display
to request immediate drawing (and IJulia will automatically remove the Plot
object from the redisplay queue in this case).One slight annoyance in our mock-up was that if I did plot
again in a later IJulia input cell, it somehow added the plot to the previous output rather than in the new output. Possibly I just screwed something up with the div
tag. If you want something to happen automatically at the end of each (multiline) input cell, e.g. drawing any plots that weren't yet drawn, or setting something up so that subsequent cells will create separate plots, you can do it with:
if isdefined(Main,:IJulia)
Main.IJulia.push_postexecute_hook(my_hook)
end
where my_hook()
is a thunk function.

Picking good colors is an old problem, but see e.g. http://colorbrewer2.org/. Or perhaps port @timholy's MATLAB code up on File Exchange http://www.mathworks.us/matlabcentral/fileexchange/29702
That's interesting. I have a lot of color spaces implemented, but haven't spent a lot of time on actually selecting colors. I'm just choosing equidistant hues in LAB space.
@dcjones, your algorithm sounds quite similar to the one I developed. The main difference possibly being that you can ask it to avoid the background (or multiple other "reserved" colors).
You're also not fixing chroma and lightness like I am. It makes sense to vary only hue (or only lightness) to show quantitative data, but qualitative scales like this might benefit by choosing from a wider range of colors.
I might try adding colorbrewer's scales, but I tend to prefer algorithms to anything "hand curated". If anyone knowns of any papers on maximizing distinguishability with constraints for colorblindness (and maybe printability), I'd be interested.
@pao:
I didn't do a deep search to see what ColorBrewer is doing behind the scenes--I can't imagine those were all created by hand, but maybe they were? Penn State is mentioned in the footer, so there might be some publications.

I like the syntax plot([f, g], a, b)
and find wish that vstack had the same interface:
Gadfly.vstack(ps::Vector{Plot}) = Gadfly.vstack(ps...)
It makes the calling a bit more verbose, but more consistent. Would you entertain adding and exporting this so vstack
can be called without explicitly loading Compose?
MIT (like Julia) would be my vote.

Hi!
I found this error on my latest Julia:
Julia Version 0.2.0-714.r1840
Commit 184054dcde 2013-03-24 16:23:04
Platform Info:
OS_NAME: Linux
Using: (64-bit interface)
Blas: libopenblas
Lapack: libopenblas
Libm: libopenlibm
Here the example I found when I tray to do a simple x,y scatterplot:
julia> data
91x2 DataFrame:
contactos rmsd
[1,] 0.0 0.073
[2,] 0.0 1.677
:
[90,] 17.0 0.544
[91,] 18.0 0.479
julia> plot(data,{:x => "contactos", :y => "rmsd"},Geom.point)
Error showing value of type Plot:
ERROR: no method classify_data(DataArray{Float64,2},)
in render at /home/dzea/.julia/Gadfly/src/Gadfly.jl:244
in repl_show at repl.jl:12
Best!
P.S.: Maybe would be great have a simple default scatterplot version for a simple call like plot(x::Vector,y::Vector)
Sorry, this is more a question than an issue.
Is there some way to plot histograms with of different groups via color?
plot(df, x = "score", color = "target", Geom.bar)
This works for scatter plots
plot(df, x = "score", y = "duration", color = "target", Geom.point)
How I can get a easy copy&paste code for publish on my blog a Gadfly's interactive plot.
Maybe can be great an embed()
for send to the clipboard that needed code (?)
Thanks!
I'm using Julia 0.1.2 c4b3649-WINNT-i686 on Windows 7...

false
When I type 10.3 * 3 I get 30.900000000000002 instead of 30.9, I'm no expert but I don't get this when I type it into R and I suspect something is wrong.

At line 255 or so of Gadfly.jl you repeat a code chunk, likely some odd copy and paste. However, one is missing this: t = classify_data(getfield(plot.data, var)) and it causes an error:

I had the same issue with my own code.

Hi,
I am seeing the following error while trying to use Gadfly.
I am on the master branch of Julia.

Hi,
I managed to add additional gems but not mappings without an error:
julia> p = plot(mpg, x = "cty", y = "hwy", Geom.point)
julua> push!(p.layers, layer(Geom.line))
julia> push!(p.layers, layer(x = "displ", Geom.line))

Hi!
This is cosmetic
Is you past over a point, the point is selected.
But is you go out of the plot area, the same point is still select.
Maybe can be great if go out of the plot area breaks the point selection in order to see again all the plot.
Thanks!
I am using Safari 6.0.2. Good news is that when I try the julia 0.1 mac binary, Pkg.add("Gadfly")
goes through error-free (although it is amazing how many packages it pulls in).
I then try the simplest example from overview as a sanity check:
p = plot([sin, cos], 0, 25)
A Finder window opens up with a temp file, and a new browser tab opens up, but it is empty. Trying the draw
command after plot
leads to an error:
julia> draw(SVG(6inch, 3inch), p)
ERROR: draw not defined
It would be great if the dependencies on Cairo and Fontconfig could be removed, from an ease of installation perspective.
