Cone Action Spectra Human Cone Action Spectra In most vertebrates that have what humans term “color vision”, there appear to be three classes of cones, based on their absorption spectra. Although many fundamental aspects of color vision remain to be worked out, the chemistry of the cones’ visual pigments is pretty much the same as in the rods. A photon is absorbed by a cis-11-retinal, converting it to the trans- configuration and initiating the phototransduction process. One of the most important differences between cones and rods is in the amino acid sequence of the opsin component of the rhodopsin molecule. You can see that in spite of their names (“Red”, “Green”, and “Blue”), each class of cone shows an absorption, or action, spectrum that extends over a range of wavelengths, with the result being considerable overlap in the three action spectra.
Presenteer.js Introduction Presenteer.js a very flexible HTML5 presentation tool that works in one line of code, but is configurable with constructor options and many callbacks. In its simplest form, it works like And then navigate through the presentation with presentation.start();, presentation.next();, presentation.prev(); and presentation.show(0-based-index); Installation Include jQuery and Presenteer.js (and possibly Sylvester.js, see below) in your page. Create the HTML and style it with CSS Then, on page load, create a Presenteer instances for every presentation on the page. I set followElementTransforms to false to make Presenteer not follow element transforms. And set followElementTransforms: true. Constructor options Apart from the followElementTransforms constructor argument, there's many more options and callbacks. Where canvas is a selector or jQuery element of the canvas on which the presentation is placed. The list of elements on the canvas is specified in the elements argument. Navigation 1.

créer un site web statique hébergé sur github - cybermonde.org Vous utilisez peut-être github pour héberger vos dépôts logiciels (repositories), voyons comment créer un site web (statique) qui ne sera rien d'autre qu'un dépôt parmi les autres. Il existe une autre variante qui consiste à créer un site au sein d'un projet existant, nous n'envisagerons pas ce cas dans le cadre de cet article. Pour notre exemple, nous allons utiliser mon nom d'utilisateur : cybermonde Le site sera accessible à l'adresse J'ai ajouté un domaine personnalisé : Ce domaine est configuré chez Gandi. La documentation complète est disponible ici : Créer le dépôt dont le nom sera obligatoirement : votrenomdutilisateur.github.io Ici : cybermonde.github.io Toutes les autres options sont facultatives, je vous conseille de donner une description, d'ajouter un readme et surtout de laisser le dépôt public. Je suppose que vous êtes familier avec les commandes de bases de Git. Créons :
Remixing Data Visualization, by Alessio Macrì [This is a guest post by Alessio Macrì*, about the infographic he created as part of the "Remixing data visualization" workshop, at Resonate 2014, in Belgrade. The visualization compares the sovereign debt exposure of sixty-one European banks to the twenty-nine nations of the old continent.] Last April, I attended an information design workshop at Resonate 2014. Resonate is an aggregator of brilliant names related to media art, programming, technology, data visualization, visual and interaction design. It brings together the best experts from all over the world. It’s a small dip in future technologies related to art and culture. image via In this context, I had the opportunity to participate at the workshop held by Accurat – Information Design, a studio based in Milan and New York that deals with static data visualization (for printing) and interactive visualization (cross-platform).

Welcome - Polymer 1.0 Three Ways to Tell Stories with Data JuxtaposeJS — Northwestern University Knight Lab Color Survey Results Who in the rainbow can draw the line where the violet tint ends and the orange tint begins? Distinctly we see the difference of the colors, but where exactly does the one first blendingly enter into the other? So with sanity and insanity. —Herman Melville, Billy Budd Orange, red? I don’t know what to believe anymore! I WILL EAT YOUR HEART WITH A FUCKING SPOON IF YOU AKS ANY MORE QUESTIONS ABOUT COLORS —Anonymous, Color Survey Thank you so much for all the help on the color survey. First, a few basic discoveries: If you ask people to name colors long enough, they go totally crazy. Overall, the results were really cool and a lot of fun to analyze. Sex By a strange coincidence, the same night I first made the color survey public, the webcomic Doghouse Diaries put up this comic (which I altered slightly to fit in this blog, click for original): Basically, women were slightly more liberal with the modifiers, but otherwise they generally agreed (and some of the differences may be sampling noise).
5 Rules For Making Graphs I went with the idea that I'm writing this for a kinja audience who all knows the views/uniques shorthands That makes sense for this audience. I mention it because I tend to be much more cautious with explainers I put online because they are available to a much wider audience than one necessarily intends. The x-axis labels are already in a format that's typically used for dates and it's a lineplot, and Summer is in the title. Like this is something that people will pick up. Ha, you say that, but when I first looked at the chart, my brain was like, hmm, I wonder what all those fractions are for? Sorry was getting sloppy here 'cause I'd just plotted the exact same data as a line plot and bar graph and so I figured people would infer from context Oh, yeah, I get that, and it definitely made sense following the rest of the post.
Spotting Bad Data Visualizations Good (or bad) Data visualizations can significantly help (or hurt) your case. Learn more about how poorly people can spot bad data visualizations. To explore how people identify and respond to bad data, Software Advice created an online survey, collecting nearly 800 total responses from randomly selected U.S. adults. We also spoke to data visualization experts for advice on how you should be presenting your data. Here’s what we found. Most People Can Spot Bad Data Visualizations When it comes to making mistakes in your charts, graphs and other visual data representations, do people really notice? Which of the following charts/data visualizations have something wrong with them? The first option was an image portraying percentages of “yes” and “no” answers, scaled with incorrect proportions. Two of the other options (B and D) were charts that had nothing wrong with them. Excerpted from Software Advice, a data visualization software review site. Related:
