I need to share an interactive plot made using the PlotlyJS package in Julia. According to the documentation of the package PlotlyJS.jl, I need to use the "savehtml" function and set "js" argument to ":embed" in order to view it offline (screenshot attached). However, I got an error "UndefVarError: savehtml not defined". Can anyone tell me what may cause this problem?
FYI, the "savefig" function can save the plot into an HTML but the HTML cannot be viewed on other machines.
It is also acceptable if there is another way to save an HTML plot that can be assessed from other machines. The interactive plot is generated by PlotlyJS.jl.
Thanks very much in advance.
This creates a standalone file that can be used on other machines.
However, those other machines need to have access to the internet:
p = PlotlyJS.Plot(sin.(1:0.1:10))
open("f.html","w") do f
PlotlyJS.PlotlyBase.to_html(f, p; include_plotlyjs="cdn", full_html=true)
end
I just checked that this is as far as you can do as of today (version v0.8.18) as there is a bug in the source code of PlotlyBase.

I am taking a class on using Octave for machine learning algorithms, and as part of the assignments, they provide a series of .m files to build upon with our own code as well as to run for submission credit through the auto-grader. My problem is that the .m files load perfectly fine in a regular text editor program like Atom or Notepad, but in Octave, the files are best described as nonsense, and thus will not run in the console. If I open the files in a regular editor and copy/paste over the crazy into Octave, it seems to save it and reopen fine. But, I have close to 20 files for the first project alone, and this solution is untenable in the long run. I have a screenshot of how it's loading. Is there some setting I need to change? Uninstall/reinstall Octave? I'm new to Octave and the Octave GUI, and I'm striking out with Google for a solution. I am using version 6.2.0. Thank you for any help/advice!
screenshot of how octave is loading my .m files
Update: I responded to this in a comment below, but I tried loading it another way into Octave GUI and received the following error: ">> error: load: unable to determine file format of 'C:/Users/sophi/documents/octave/assignment_1/computeCost.m" This tracks for me because it makes sense why it would open the files in such a weird way. It's simply not sure what they are. However, I created my own simple functions from scratch to test, saved them as .m files, and was able to run them perfectly fine. I'm including one of the files below. Maybe there's a key in the formatting of the files offered by the class which is impacting Octave's ability to process it correctly?
function plotData(x, y)
%PLOTDATA Plots the data points x and y into a new figure
% PLOTDATA(x,y) plots the data points and gives the figure axes labels of
% population and profit.
figure; % open a new figure window

% Instructions: .... goes on about assignment

MOST RECENT UPDATE: The plot thickens. Yesterday, I was able to open the files I created and run them in the Octave environment, and I (wrongly) assumed they would still work today. They are doing the same stupid thing as the files included by the course. I checked inside preferences for the editor, and it says it is loading and saving them as IBM273 if that helps. Thank you for everyone has pitched in ideas. I really appreciate it!
It was 100% the encoding. I thought it was strange it was saving/loading in IBM273, so I switched it to UTF-8. Almost all the files are working now. The only ones that aren't are the ones I was trying to copy/paste yesterday to see what was going on with the load problems and the basic new problems I wrote. So I deleted everything, redownloaded, and set the default UTF-8 going forward and voila! Solved! Thanks again!
If you want to open a .m file in octave, Try this solution
It is necessary to declare a current directory before saving a file, loading a file, or running an M-file. By default, unless you edit the Octave shortcut, the current directory will be .../Octave/work. After you start Octave, change the current directory by either using the toolbar at the left-hand side of the screen, or entering the path in the bar at the top.
To open an .m file, you can use file -> open, or type
open filename
So I was using the neo4jrestclient, and I noticed that in the class of QuerySequece, there's a .to_html()function (https://github.com/versae/neo4j-rest-client/blob/master/neo4jrestclient/query.py)
However, when I try using it I get the 'Unable to display the graph or the table' error.
I haven't found a working example of it. I was wondering if anyone has gotten this working.
Much thanks appreciated.
The function .to_html() is a function that IPython uses in order to render rich content inside Notebooks. When running inside a Notebook, neo4jrestclient asks for extra information to the Neo4j server, so it can draw the actual graph returned. Therefore, if you try to run a query inside an IPython Notebook, a D3 graph should be rendered automatically.
from neo4jrestclient.client import GraphDatabase, Node, Relationship
gdb = GraphDatabase(url="http://localhost:7474")
gdb.query("MATCH (me)-[r]-() RETURN me, r LIMIT 10")
A running example can be seen in this gist. Although it's still a work in progress. I think that I could add an option to populate the needed fields in case you wanted to use the .to_html() outside the IPython Notebook. All you need to do is to make neo4jrestclient believe that it's running inside of one by modifying the function neo4jrestclient.utils.in_ipnb() making it to always return True. Let me know if you would use that feature and I will add it.
On the other hand, I am developing ipython-cypher, to have a better integration of IPython, Pandas, NetworkX, and matplotlib with Neo4j, but it's still in alpha.
Update: Now you can add data_contents=True to return the extra data.
results = gdb.query(query, data_contents=True)
Data will be in results.rows and results.graph.
I'm relatively new to batch commands and have been learning steadily. My problem is like this:
I've understood how to kill processes using batch commands using many different methods. However, I've been unable to figure out how to close a single tab in, preferably, chrome.
Any thoughts would be greatly appreciated!
Thanks!
So, I suppose I should state my exact problem.
I'm using notepad++ as my LaTeX compiler and sending the final pdf to chrome. The reason: I usually have ~20 tabs open related to the project I'm working on and it just makes my work much easier to split my screen between notepad++ and chrome.
My current batch file compiles the LaTeX code and sends the compiled document to chrome as a new tab. For obvious reasons, i don't want to close a tab each time I compile, so I thought that closing the current tab at the same time during compiling would solve my problem. But, I just can't find a way to get my batch file to only close the tab with my compiled pdf.
Thanks in advance!
check all running chrome instances/tabs with :
wmic process where "caption='chrome.exe'" get
and see processes properties.Probably the best indicator that you can rely on in this case is CreationDate (other properties are basically the same for all chrome instances) - it always comes in format YYYYMMDDHHmmss.ms and is easy for string comparison.But you'll have to know the time when it was started.
I'm trying to port some existing code to WP8 and have come across a problem.
The code i am porting uses a smart pointer thats is defined in comdef.h but for some reason when I try and include comdef.h I get the following error.
comdef.h(25): fatal error C1083: Cannot open include file: 'olectl.h'
I understand what the error means and it seems there is no trace of "olectl.h" in the WP8 SDK include paths on my machine. Is anyone else having this problem, I've tried "repairing" my installation of "Visual studio 2012 Express for Windows Phone"
I have found some code that appears to include comdef.h and has gotten around the missing macro problem the link at the end of this post is talking about by not using the macro at all and explicitly using the code that the macro would expand to.
(Here is the code that does what I want to: https://devel.nuclex.org/framework/browser/graphics/Nuclex.Graphics.Native/trunk/Source/Rasterization/Direct3D11/Direct3D11Api.h?rev=1782)
Has anyone else experienced this, or could someone with the SDK installed try including comdef.h somewhere to see if it works for them.

Thanks.
Yes, I see this too, so it appears this is "by-design".
Basically if the API isn't listed on MSDN in the list of supported COM/Win32 APIs, then it isn't a supported API on Windows Phone 8. It looks like only the combaseapi.h header is supported.
_com_ptr_t<T> and it's friends aren't on the list...
I'm thoroughly confused about how to read/write into igraph's Python module. What I'm trying right now is:
g = igraph.read("football.gml")
g.write_svg("football.svg", g.layout_circle() )
I have a football.gml file, and this code runs and writes a file called football.svg. But when I try to open it using InkScape, I get an error message saying the file cannot be loaded. Is this the correct way to write the code? What could be going wrong?
The write_svg function is sort of deprecated; it was meant only as a quick hack to allow SVG exports from igraph even if you don't have the Cairo module for Python. It has not been maintained for a while so it could be the case that you hit a bug.
If you have the Cairo module for Python (on most Linux systems, you can simply install it from an appropriate package), you can simply do this:
igraph.plot(g, "football.svg", layout="circle")
This would use Cairo's SVG renderer, which is likely to generate the correct result. If you cannot install the Cairo module for Python for some reason, please file a bug report on https://bugs.launchpad.net/igraph so we can look into this.
(Even better, please file a bug report even if you managed to make it work using igraph.plot).
Couple years late, but maybe this will be helpful to somebody.
The write_svg function seems not to escape ampersands correctly. Texas A&M has an ampersand in its label -- InkScape is probably confused because it sees & rather than &. Just open football.svg in a text editor to fix that, and you should be golden!
