  • Howto format a date as localized Short MonthDay string

    - by Wouter
    I would like to format a DateTime to a string containing the month name abbreviated and the date for use in axislabels in a graph. The default DateTime format strings do not contain abbreviated month. I guess there is no standard but I could take a substring of the first 3 characters of the month name and replace this into the MonthDay format. The reason I would use MonthDay is that the ordering of month and date is locale dependent. Does anyone have a better idea? http://msdn.microsoft.com/en-us/library/az4se3k1.aspx#MonthDay

  • Getting empty result within PHP when in browser I get the JSON exception

    - by Pentium10
    I have this code: $url="https://graph.facebook.com/me/friends?access_token=".$access_token."&fields=id,first_name,last_name&limit=10"; $content=file_get_contents($url); Whenever I use this on a non authenticated user I should get feedback of OAuthException, which doesn't show up in the PHP the $content is empty. While if I copy the URL to the browser I get the result and I see the exception. I want to detect if the user is logged in and the session data is valid. What might be wrong?

  • Multiple outliers for two variable linear regression

    - by Dave Jarvis
    Problem Building on my previous question, the "extreme" outliers in the following graph are somewhat obvious: Question Given: T - Set of all temperatures Y - Set of all years ST - Sum of temperatures. SY - Sum of years. N - Number of elements T(n) - Temperature of the nth element in the temperature set How would you implement an efficient MySQL stored procedure or user-defined function (UDF) to determine if T(n) is an outlier? (If such an implementation already exists, that would be good to know as well.) Related Sites I am slowly working through these sites to get a better understanding of the problem: Multiple Outliers Detection Procedures in Linear Regression M-estimator Measure of Surprise for Outlier Detection Ordinary Least Squares Linear Regression Many thanks!

  • How to detect code duplication during development ?

    - by David Dibben
    We have a fairly large code base, 400K LOC of C++, and code duplication is something of a problem. Are there any tools which can effectively detect duplicated blocks of code? Ideally this would be something that developers could use during development rather than just run occasionally to see where the problems are. It would also be nice if we could integrate such a tool with CruiseControl to give a report after each check in. I had a look at Duploc some time ago, it showed a nice graph but requires a smalltalk environment to use it, which makes running it automatically rather difficult. Free tools would be nice, but if there are some good commercial tools I would also be interested.

  • Simple javascript string problem in ie6 and ie7

    - by Jeff Lamb
    I have a very simple function that takes a list of comma separated (x,y) points and imports them into a graph. I have FF, Chrome and IE8 installed. I use IETester to test for IE6 and IE7. // Import Data this.Import = function(data) { alert("Data in: "+data); var d; // Make sure the first and the last are start/ending parenthesis if ( (data[0] != '(') || (data[data.length-1] != ')') ) { alert("After if: "+data[0]+" "+data[data.length-1]); return false; } ... In Chrome, FF and IE8, I don't see the "After if:" alert. In IE6 and IE7, I see the following two alerts: Data in: (52,16),(100,90) After if: undefined undefined The "Data in" alert matches in all browsers. Any ideas?

  • PyQt: Get the position of QGraphicsWidgets in a QGraphicsGridLayout

    - by Chris Phillips
    I have a fairly simple PyQt application in which I'm placing instances of a QGraphicsWidget in a QGraphicsGridLayout and want to connect the widgets with lines drawn with a QGraphicsPath. Unfortunately, no matter what I try, I always get (0, 0) back as the position for both the start and end widgets. I'm constructing the graph with a recursive function that adds widgets to the scene and layout. Once the recursive function is complete, the layout is added to a new widget, which is added to the scene to show everything. The edges are added to the scene as widgets are created. How do I get a non-zero position of any of the widgets in the grid layout?

  • Actionscrips/Flex4: Display cut-off datapoints differently in LineChart

    - by Limited Atonement
    Dear Sirs, The issue arises when the user selects a range on the linechart that cuts off datapoints. When this happens, I would like the chart to tell the user somehow that there are data points three, just outside the range, perhaps by drawing a straight line across the top or bottom of the graph. How can I get Flex to do this for met? Let me know if you understand the question, or if you need more information, and of course, let me know the answer! Thanks! Sincerely, Aaron

  • Help understanding how to make a bar chart using ggplot2

    - by celenius
    I'm trying to use the bar_geom function of ggplot2, but I can't understand how to use it. I've made a small sample of my code to show what I am trying to do: library(ggplot2) # sample data sampleData = data.frame( v1=c('a','b','c','d','e', 'f','g', 'h', 'i','j'), v2=c(1:10) ) sampleData$Names = data.frame( Names = paste(sampleData$v1, sampleData$v2, sep="") ) sampleData$Values = c(1:10) # make plot x = sampleData$Values y = sampleData$Names qplot( x, y, data = sampleData, geom="bar" ) I want sampleData$Names to be on the x-axis of my graph, labeling each bar and and sampleData$Values to scale the bar height. I want the y-axis to be specified as a range. I realize that I don't understand how ggplot2 functions as this small example does not work, yet my other example is generating a plot but I cannot specify a y-range as it considers the variables to be categorical.

  • What's the best way to view/analyse/filter huge traces/logfiles?

    - by oliver
    this seems to be a reoccurring issue: we receive a bug report for our software and with it tons of traces or logfiles. since finding errors is much easier when having a visualization of the log messages/events over time it is convenient to use a tool that can display the progression of events in a graph etc. (e.g. wireshark (http://www.wireshark.org) for analyzing network traffic) what tool do you use for such a purpose? the problem with most tools i used so far is that they mercilessly break down when you feed them huge data traces ( 1GB) so some criteria for such a tool would be: can deal with huge input files ( 1 GB) is really fast (so you don't have to get coffee while a file is loading) has some sort of filtering mechanism

  • Using Ruby Hash instead of Rails ActiveRecord in Coffeescript / Morris.JS

    - by Vanessa L'olzorz
    I'm following the Railscast #223 that introduced Morris.JS. I generate a data set called @orders_yearly in my controller and in my view I have the following to try and render the graph: <%= content_tag :div, "", id: "orders_chart", data: {orders: @orders_yearly} %> Calling @orders_yearly.inspect shows it's just a simple hash: {2009=>1000, 2010=>2000, 2011=>4000, 2012=>100000} I'll need to modify the values for xkey and ykeys in coffeescript to work, but I'm not sure how to make it work with my data set: jQuery -> Morris.Line element: 'orders_chart' data: $('#orders_chart').data('orders') xkey: 'purchased_at' # <------------------ replace with what? ykeys: ['price'] # <---------------------- replace with what? labels: ['Price'] Anyone have any ideas? Thanks!

  • How to convert a AChartEngine chart to bitmap

    - by user2137817
    I want to convert a line graph I made with AChartEngine lib to bitmap.How should I do?I didn't found on the net anything that can help. Is the toBitmap() method suitable?if yes then how to use it? Update: I used this method : public static Bitmap loadBitmapFromView(View v) { v.setDrawingCacheEnabled(true); v.layout( 0,0,800,600); v.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH); v.buildDrawingCache(); v.getDrawingCache(); Bitmap bmp = Bitmap.createBitmap(800,600, Bitmap.Config.ARGB_8888); v.setDrawingCacheEnabled(false); return bmp; } and saved the result in a png file but all I got is an empty file !

  • In Django how display all of the values aftere the for loop is finished instead of displaying them one by one

    - by Igor
    Hello, In my django project in the view I call the last 6 values in the column and send them to the template. I then would like to pass into google charts api those 6 values and have a graph. At the moment for some reason I get 6 different graphs. {% for foodbag in foodbags %} <img src="http://chart.apis.google.com/chart?chxl=0:|0|1|2|3|4|5|6&chxr=2,0,0&chxs=0,1,676767,10.5,1,l,676767|2,676767,5.5,0,l,676767&chxt=x,y&chs=300x170&cht=bvg&chco=76A4FB&chd=t:{{foodbag.12}},0&chma=0,5|5,5&chdlp=t&chtt=Food+Bags"/> {% endfor %} I'm not sure how to replace string chd=t:{{foodbag.12}}, with the 6 values I am trying to extract from foodbags. I would really appreciate the help. Thank you

  • problem with asf writer

    - by hatham
    Im trying to encode raw data(both video frame and audio sample) into .asf file, using asf writer filter in directshow. my filter graph structure: raw_send_filter - asf writer filter raw_send_filter implements CBaseFilter and CBaseOutputPin. It plays a role as source filter which get raw data, then deliver them to ASF writer filter. The process follows these steps: Get deliver buffer (return into "sample") , using the function CBaseOutputPin::GetDeliveryBuffer sample-GetPointer(&buffer); Set time stamp (with frame rate = 30 fps) deliver sample The problem is after encode some raw data, I can not deliver any more. I can encode .avi file with this way, using Avi mux filter. Can u tell me why I can not deliver samples after encoding some? Thanks.

  • Java code to convert a list of dependencies into a build order?

    - by Egon Willighagen
    Given I have a list of dependencies, like: module1 module2 dependsOn module1 module3 dependsOn module1 module4 dependsOn module3 I would like to create a build order where each build step is found on one line, and each line contains a list of one or more modules which can be compiled at the same time, and which only depend on modules compiled earlier. So, for the above data set, create a list like: module1 module2,module3 module4 Now, this is basically just a problem of creating a directed graph, and analyzing it. Now, I am using Ant, and would very much like to use something off-the-shelf... what is the minimum of custom code I need to have it create such a dependency-aware build list starting from the given input? BTW, these modules are actually custom modules, so maven will not work.

  • Recommendation for web-based database visualization tool

    - by prometheus
    Tableau is extremely flexible when it comes to visualizing and playing around with datasets, but it is extremely slow when you go into "production mode" and publish a particular view that you've created onto your server. Does anyone know of any tools that can be used to connect to a database, present interactive (or somewhat interactive) dashboards, and perform reasonably well when published to a server? To be clearer, I am looking for something like this -- http://www.corda.com/executive-dashboard-graph-styles.php. I realize that such a product might not exist. If so, is there a particular framework or library that I could use to create killer interactive visualizations of data for the web?

  • How to integrate junit/pmd/findbugs report into hudson build email?

    - by fei
    my team is looking into using hudson as our continuous integration software, 1 problem that we try to figure out is to integrate the reports of junit/pmd/findbugs etc into the build email that get sent to the team. the graph/reports on the dashboard are nice and all, but people usually want to just read the email and not clicking the links. i tried to use the ext-email plugin, but that doesn't provide much help related to this. is there any way i can get those info into the build email? Thanks!

  • Capture Flash Audio in 4.7 Edge?

    - by emcmanus
    Is there a way to capture plugin (Flash) audio before it gets to the sound card? I'd like to record plugin audio, hopefully without actually playing the sound. Capturing audio at the device level is an absolute last resort, as the application would pick up all system audio rather than just the Webkit plugin. I'm aware of the recent switch back from QTMultimedia; is this possible with phonon? I spent the night looking for some way to access the phonon graph via QWebFrame (or any of the QtWebkit widgets) -- and didn't turn up much. I also started digging through QTWebkit, particularly NPAPI, without success. For reference, I'm using the edge version of 4.7 (6aa50af000f85cc4497749fcf0860c8ed244a60e) This seems to be a fairly challenging problem. Any hints would be greatly appreciated.

  • Cloned Cached item has memory issues

    - by ioWint
    Hi there, we are having values stored in Cache-Enterprise library Caching Block. The accessors of the cached item, which is a List, modify the values. We didnt want the Cached Items to get affected. Hence first we returned a new List(IEnumerator of the CachedItem) This made sure accessors adding and removing items had little effect on the original Cached item. But we found, all the instances of the List we returned to accessors were ALIVE! Object relational Graph showed a relationship between this list and the EnterpriseLibrary.CacheItem. So we changed the return to be a newly cloned List. For this we used a LINQ say (from item in Data select new DataClass(item) ).ToList() even when you do as above, the ORG shows there is a relationship between this list and the CacheItem. Cant we do anything to create a CLONE of the List item which is present in the Enterprise library cache, which DOESNT have ANY relationship with CACHE?!

  • Double linking array in Python

    - by cdecker
    Since I'm pretty new this question'll certainly sound stupid but I have no idea about how to approach this. I'm trying take a list of nodes and for each of the nodes I want to create an array of predecessors and successors in the ordered array of all nodes. Currently my code looks like this: nodes = self.peers.keys() nodes.sort() peers = {} numPeers = len(nodes) for i in nodes: peers[i] = [self.coordinator] for i in range(0,len(nodes)): peers[nodes[i%numPeers]].append(nodes[(i+1)%numPeers]) peers[nodes[(i+1)%numPeers]].append(nodes[i%numPeers]) # peers[nodes[i%numPeers]].append(nodes[(i+4)%numPeers]) # peers[nodes[(i+4)%numPeers]].append(nodes[i%numPeers]) The last two lines should later be used to create a skip graph, but that's not really important. The problem is that it doesn't really work reliably, sometimes a predecessor or a successor is skipped, and instead the next one is used, and so forth. Is this correct at all or is there a better way to do this? Basically I need to get the array indices with certain offsets from each other. Any ideas?

  • How do I show the SVN revision number in git log?

    - by Zain
    I'm customizing my git log to be all in 1 line. Specifically, I added the following alias: lg = log --graph --pretty=format:'%Cred%h%Creset - %C(yellow)%an%Creset - %s %Cgreen(%cr)%Creset' --abbrev-commit --date=relative So, when I run git lg, I see the following: * 41a49ad - zain - commit 1 message here (3 hours ago) * 6087812 - zain - commit 2 message here (5 hours ago) * 74842dd - zain - commit 3 message here (6 hours ago) However, I want to add the SVN revision number in there too, so it looks something like: * 41a49ad - r1593 - zain - commit 1 message here (3 hours ago) The normal git log shows you the SVN revision number, so I'm sure this must be possible. How do I do this?

  • Program contains 2 nested loops which contain 4 if conditionals. How many paths?

    - by Student4Life
    In Roger Pressman's book, there is an example described of a program with 2 nested loops, the inner loop enclosing four if statements. The two loops can execute up to 20 times. He states that this makes about 10^14 paths. To get a number this large, it seems the paths inside the loops are multipllied by 2^40, i.e. 2^20 times 2^20 to account for all the possibilities of going through the two loops. I can't see why this factor is not just 400, i.e. 20 times 20. Can someone shed some light? It will help if you have the ppt slides and can see the program graph. Thanks.

  • Plot smooth line with PyPlot

    - by Paul
    I've got the following simple script that plots a graph: import matplotlib.pyplot as plt import numpy as np T = np.array([6, 7, 8, 9, 10, 11, 12]) power = np.array([1.53E+03, 5.92E+02, 2.04E+02, 7.24E+01, 2.72E+01, 1.10E+01, 4.70E+00]) plt.plot(T,power) plt.show() As it is now, the line goes straight from point to point which looks ok, but could be better in my opinion. What I want is to smooth the line between the points. In Gnuplot I would have plotted with smooth cplines. Is there an easy way to do this in PyPlot? I've found some tutorials, but they all seem rather complex.

  • Graphing a line and scatter points using Matplotlib?

    - by Patrick O'Doherty
    Hi guys I'm using matplotlib at the moment to try and visualise some data I am working on. I'm trying to plot around 6500 points and the line y = x on the same graph but am having some trouble in doing so. I can only seem to get the points to render and not the line itself. I know matplotlib doesn't plot equations as such rather just a set of points so I'm trying to use and identical set of points for x and y co-ordinates to produce the line. The following is my code from matplotlib import pyplot import numpy from pymongo import * class Store(object): """docstring for Store""" def __init__(self): super(Store, self).__init__() c = Connection() ucd = c.ucd self.tweets = ucd.tweets def fetch(self): x = [] y = [] for t in self.tweets.find(): x.append(t['positive']) y.append(t['negative']) return [x,y] if __name__ == '__main__': c = Store() array = c.fetch() t = numpy.arange(0., 0.03, 1) pyplot.plot(array[0], array[1], 'ro', t, t, 'b--') pyplot.show() Any suggestions would be appreciated, Patrick

  • Problem requesting a HTTPS with TCL

    - by Javier
    Hi Everybody, I'm trying to do the following request using TCL (OpenACS) http::register https 443 tls::socket set url "https://encrypted.google.com" set token [http::geturl $url -timeout 30000] set status [http::status $token] set answer [http::data $token] http::cleanup $token http::unregister https The problem is that when I read the $status variable I get "eof" and the $answer variable becomes empty. I tried enabling tls V.1 http::register https 443 [list tls::socket -tls1 1] and it works only for the site https://www.galileo.edu, but not for https://encrypted.google.com. The site what I'm trying to connect is https://graph.facebook.com/me/feed?access_token=... but it doesn't work. I used curl to retrieve the contents of the pages in HTTPS and it works, I have installed OpenSSL, so I can't see the problem, there is another way to do HTTPS connections with TCL?. I can't see if this is a problem of coding (maybe I'm registered wrong the https protocol) or maybe It is a bad configuration of my server. Hope somebody helps!! Thanks!
