  • Interpolation on Cubism graphs

    - by Abe Stanway
    Cubism was designed, by mbostock's own words, for maximum information density - which means it generally wants to display one datapoint per pixel. While this is useful in many cases, it doesn't help when your data itself is not that dense. In these cases, you get ugly, staccato-style graphs like so: Is there a way to interpolate my data/graph within Cubism to show a nice, smoothed graph? EDIT: After adding keepLastValue to the metric, I get this: Here is the same data as shown in Graphite: I would like to smooth the Cubism view to look more like Graphite (with the added awesomeness of the horizon overplotting)

  • Creating a floating button

    - by Robert Smith
    Hey all, I'm working on a Firefox extension and am out of ideas on how to implement a floating button. I need a button that is overlayed on my page that I can show/hide and dynamically position just about anywhere on my page. I thought I could do something like a fancy CSS tool-tip except replace it with button functionality, but that idea failed because I couldn't pull my example apart well enough to understand what all I need to include, need to change, etc. I've thought about using jQuery(though wouldn't mind avoiding, unless it makes this painfully easy) but will be looking more into that as a possibility now. If anyone can offer a tutorial link, ideas, sample code, anything to help get me moving in the right direction I will greatly appreciate it! Thanks! Edit: Clarification I'm not entirely sure how to actually create the overlayed button. I tried to create a a floating div with some text in it, and nothing showed up, but I got no errors, which means I'm doing something wrong, but I have no idea what that is. http://www.fijiwebdesign.com/blog/css-tooltips-floating-html-elements.html If you take a look at that webpage you see that there is that floating "feedback" button, I would like to create something similar, only it wouldn't be anchored to the sides, but I could position it over text, etc. #floatingBtn { position: absolute; z-index: 10000; top: 50%; left: 50%; } Thats the CSS I used to try and float my div. I don't know if I'm creating the div in the wrong place or... I thought if I could get a floating div with some text, I could turn that into my button.

  • Can I execute a "variable statements" within a function and without defines.

    - by René Nyffenegger
    I am facing a problem that I cannot see how it is solvable without #defines or incuring a performance impact although I am sure that someone can point me to a solution. I have an algorithm that sort of produces a (large) series of values. For simplicity's sake, in the following I pretend it's a for loop in a for loop, although in my code it's more complex than that. In the core of the loop I need to do calculations with the values being produced. Although the algorithm for the values stays the same, the calculations vary. So basically, what I have is: void normal() { // "Algorithm" producing numbers (x and y): for (int x=0 ; x<1000 ; x++) { for (int y=0 ; y<1000 ; y++) { // Calculation with numbers being produced: if ( x+y == 800 && y > 790) { std::cout << x << ", " << y << std::endl; } // end of calculation }} } So, the only part I need to change is if ( x+y == 800 && y > 790) { std::cout << x << ", " << y << std::endl; } So, in order to solve that, I could construct an abstract base class: class inner_0 { public: virtual void call(int x, int y) = 0; }; and derive a "callable" class from it: class inner : public inner_0 { public: virtual void call(int x, int y) { if ( x+y == 800 && y > 790) { std::cout << x << ", " << y << std::endl; } } }; I can then pass an instance of the class to the "algorithm" like so: void O(inner i) { for (int x=0 ; x<1000 ; x++) { for (int y=0 ; y<1000 ; y++) { i.call(x,y); }} } // somewhere else.... inner I; O(I); In my case, I incur a performance hit because there is an indirect call via virtual function table. So I was thinking about a way around it. It's possible with two #defines: #define OUTER \ for (int x=0 ; x<1000 ; x++) { \ for (int y=0 ; y<1000 ; y++) { \ INNER \ }} // later... #define INNER \ if (x + y == 800 && y > 790) \ std::cout << x << ", " << y << std::endl; OUTER While this certainly works, I am not 100% happy with it because I don't necessarly like #defines. So, my question: is there a better way for what I want to achieve?

  • Get the window height

    - by Mitchan Adams
    This is frustrating me. It should be something really simple but I can't get it to work IE. I want to get the height of the current window. Not the scroll height, not the document height, the actual window height. I've tried window.innerHeight which returns undefined and document.documentElement.clientHeight which gives the scroll height.

  • Ajax request with prototype - what is transport if not only responseText?

    - by Delirium tremens
    This is an example code from the prototype site. var url = '/proxy?url=' + encodeURIComponent('http://www.google.com/search?q=Prototype'); // notice the use of a proxy to circumvent the Same Origin Policy. new Ajax.Request(url, { method: 'get', onSuccess: function(transport) { var notice = $('notice'); if (transport.responseText.match(/href="http:\/\/prototypejs.org/)) notice.update('Yeah! You are in the Top 10!').setStyle({ background: '#dfd' }); else notice.update('Damn! You are beyond #10...').setStyle({ background: '#fdd' }); } }); The data that comes from the ajax request is available at transport.responseText, but what is transport if not only responseText?

  • jquery replaceWith implications

    - by Vlad Ioffe
    I am using replaceWith for input type=file to handle changes of the file the user wants to upload. I have this code: $('#add_cv_input').change(function() { // here is some code else { alert('put one of this: pdf doc docx'); $("#add_cv_input").replaceWith('<input id="add_cv_input" type="file"/>'); } }); now the problem is that this jquery changed event does not being called after the first time that the user had uploaded the wrong extension. I don't have a clue why this is happening. Everything works fine if at the first time the user uploads a valid extension and then he changes it to other valid extension.

  • Creating a clickable progress bar

    - by Cory
    What I'm essentially building is a webkit based controller that communicates with a program called Ecoute.app. The controller has a progressbar that indicates the progress made through the currently playing song, but I want to make this bar's position adjustable with a click. function barClick() { var progress = Ecoute.playerPosition(); var width = 142.5; var percentElapsed = progress / length; var position = width * percentElapsed; Ecoute.setPlayerPosition(position); } Is what I have, with Ecoute.playerPosition() returning the player's current position. Width has previously been defined as a dynamic value at var width = 142.5 / length * progress + 1.63; With length being the current track length and progress being the player's position. This has been able to dynamically stretch a progression overlay image to indicate the position of the track via the desktop controller. However, the max width used in the second function does not appear to allow the first function to work properly. Any help possibly determining the correct value or approach would be hugely appreciated.

  • Manipulating/changing adressbar link Help

    - by Karem
    I am out of my own "ideas" going through this. I have a album viewer. When you click next I want the adressbar to hang with it, e.g if you start on ?photoid=1, and click next (next picture appends and stuff), and then i want it to say ?photoid=2. Now I cant make it say ?photoid=2 without changing/manipulating, and this you cant do without HTML5. I have made a script in HTML5 that works fine, but then I need to take care of those who dont have HTML5(only chrome, ff4 etc supports html5) Made the script from this( https://developer.mozilla.org/en/DOM/Manipulating_the_browser_history ) I thought of adding #photoid=2 so, ?photoid=1#photoid=2 and then check if theres anything in # then use that instead of the $_GET.. But apparently you cannot do that as # is client side handled and never sent to the server. So what should I then do? Any suggestions please to make a workaround this? I checked facebook, what they did to IE users, and I could hear that it "clicked" (the annoying click sound from IE) twice.. the first was to get to the next picture, the second click sound changed the adressbar?!(how?). And then I also thought hey, html5 is only supported in ff4, and I got ff3.6, and they manipulate the adress bar url when you browse through the album photos, exactly like how I wanted (and what I have written for but it only works in Chrome and ff4..?). How could they do that?

  • JQGrid: Dynamically set a cell to uneditable based on content

    - by Shawn
    I'm having some issues getting some cells (with cellEdit: true) to be non-editable even though the column is set to editable. I've tried many ways, like beforeEditCell, formatters, etc. None seem to work. The closest I've got is by setting a formatter to the column that I'd like to be editable and then using setCell to set the 'not-editable-cell' class (snippet below). The first time you click the cell, it unfortunately goes into edit mode, but if you click elsewhere and try to re-edit the cell, it's successfully uneditable. I've also tried using the same snipped but inside of beforeEditCell, it successfully stops the cell from being edited but in turn 'freezes' the grid. You can no longer select any other cell. function noEditFormatter(cellValue, options, rowObject) { if (cellValue == 'test') jQuery("#grid").jqGrid('setCell', options.rowId, 'ColName', '', 'not-editable-cell'); return cellValue; } Any help would be much appreciated.

  • How does the dispatch action call work in the Twitter sidebar

    - by phwd
    I would like to understand how the call for replies works as follows: <a href="http://twitter.com/replies" data="{"dispatch_action":"replies"}"> <span>@phwd</span> </a> This was taken from the homepage of Twitter. The section in particular being: data="{"dispatch_action":"replies"}" I believe (think), it is using Twitter's own twitter.js script and I do not want to interfere(or copy) with their code, I rather just want to know how the call works. My current setup is using Abraham's twitteroauth PHP library, jQuery and some Ajax to refresh the portion of the page needed using the following method : Use jQuery and PHP to build an Ajax-driven Web page [IBM link - I am a new user so I can only post one link] I apologize if this question is not formatted/worded well, it is my first time. Also I tried searching DocType and StackOverFlow. The Related Questions show me Struts but I am not sure it is that.

  • Align objects to curve with canvas

    - by mitjak
    Is it possible? I'm learning canvas at the moment, and while it's fun to position objects programmatically, it would be most interesting to come up with a way to align them to a curve. E.g. align a series of squares back to back along a wavy line or a circle.

  • Altering IFrame src content

    - by Nick
    I dont believe this can be done, but is it possible to alter the content of an iframe that is rendered via a src. The 3rd party compiled ASP.Net control (Telerik RadEditor .Net 2 version) I use has an iframe in part of its rendered code and does not contain a doctype and it is causing problems in IE8 with certain elements. As it is compiled, I can not add it in the source. I was wondering if it is possible to add it in another way? I have tried multiple things in jquery such as: $(element).html().prepend("doc type here"); $(element).html("doctype here" + $(element).html()); and all other kinds of dodgy work.

  • Fluid width Son of Suckerfish dropdown menus

    - by derekerdmann
    For CSS dropdown menus, I usually stick with the Son of Suckerfish dropdowns. The technique works extremely well, but there's one small thing that's always bothered me: the width of the dropdown links is always fixed. Are there any ways to automatically resize the width of the items in a Suckerfish dropdown menu? If not, are there any other CSS-based dropdown menu strategies that can accomplish this?

  • JQuery UI: is it possible to know where an object has been dropped?

    - by Jack Duluoz
    Hi, what I want to do is to know where (not in terms of position (x, y), but a reference to the DOM element) an object was dropped. I have a grid made up with divs where you can drop various items and I need to know which div on the grid was the item dropped on (getting its id would be fine). The callback function function(event, ui) { //code here } has just that ui object who doesn't apparently contain any information about this, but only about the draggable item or its helper.

  • element height after content change

    - by Neph
    I have a snippet of code that alters the contents of a DIV to match the contents of a textarea and then applies the height change in the DIV to the textarea element. function growTextArea(parameter) { $('div').find("[data-fieldid='1_description']").text($(parameter).val()); // No Works height = $('.hiddenDiv').find("[data-fieldid='1_description']").outerHeight(); alert(height); // Works heightDiv = $('.hiddenDiv').outerHeight(); alert(heightDiv); $(parameter).css('height', $('div').find("[data-fieldid='1_description']").outerHeight()); } The DIV contents change properly, so the search function is working properly, however the search function always returns the original height of the DIV. The function is called by onKeyUp in the textarea. If the .find is swapped out for a .hiddenDiv the height change is reflected properly.

  • JQuery Slide Onclick

    - by everreadyeddy
    I am using the code in example http://www.faridesign.net/2012/05/create-a-awesome-vertical-tabbed-content-area-using-css3-jquery/ I am trying to slide the div tags on a button click on the list so the current tab-content will slide in and the tab just clicked will slide out. I currently have the working example where I can switch between divs fine, but I need to slide in and out between divs. Is there any script I can do this with the current code. using .slide or .effect instead of .show() looks to display two divs at the same time. I'm not sure what I am doing wrong. <div id="v-nav"> <ul> <li tab="tab1" class="first current">Main Screen</li> <li tab="tab2">Div 1</li> <li tab="tab3">Div 2</li> <li tab="tab4">Div 3</li> <li tab="tab5">Div 4</li> <li tab="tab6">Div 5</li> <li tab="tab7">Div 6</li> <li tab="tab8" class="last">Div 7</li> </ul> <div class="tab-content"> <h4>Main Screen</h4> </div> <div class="tab-content"> <h4>Div 1</h4> </div> <div class="tab-content"> <h4>Div 2</h4> </div> <div class="tab-content"> <h4>Div 3</h4> </div> <div class="tab-content"> <h4>Div 4</h4> </div> <div class="tab-content"> <h4>Div 5</h4> </div> <div class="tab-content"> <h4>Div 6</h4> </div> <div class="tab-content"> <h4>Div 7</h4> </div> My Script looks like $(function () { var items = $('#v-nav>ul>li').each(function () { $(this).click(function () { //remove previous class and add it to clicked tab items.removeClass('current'); $(this).addClass('current'); //hide all content divs and show current one //$('#v-nav>div.tab-content').hide().eq(items.index($(this))).show(); //$('#v-nav>div.tab-content').hide().eq(items.index($(this))).fadeIn(100); $('#v-nav>div.tab-content').hide().eq(items.index($(this))).slideToggle(); window.location.hash = $(this).attr('tab'); }); }); if (location.hash) { showTab(location.hash); } else { showTab("tab1"); } function showTab(tab) { $("#v-nav ul li:[tab*=" + tab + "]").click(); } // Bind the event hashchange, using jquery-hashchange-plugin $(window).hashchange(function () { showTab(location.hash.replace("#", "")); }) // Trigger the event hashchange on page load, using jquery-hashchange-plugin $(window).hashchange(); });

  • Find all <a>s to who's href points to an image with XPath 1.0

    - by Jeffrey Aylesworth
    First, I can assume that all urls that end with jpeg, jpg, bmp, png or gif are images, and others aren't. I thought of, and tried two solutions: Matching the regular expression .(jpe?g|bmp|png|gif)$ Using ends-with to check each separately But, it appears that neither of these exist in XPath 1.0, or at least, they don't exist in Firefox (I am writing a greasemonkey script, so it is only important for the path to work in Firefox).

  • Can events fired from an iframe be handled by elements in its parent?

    Suppose I have a page located at www.example.com/foo, and it contains an iframe with src="http://www.example.com/bar". I want to be able to fire an event from /bar and have it be heard by /foo. Using the Prototype library, I've tried doing the following without success: Element.fire(parent, 'ns:frob'); When I do this, in ff 3.5, I get the following error: Node cannot be used in a document other than the one in which it was created" code: "4 Line 0 Not sure if that's related to my problem.
