D3 SVG transform rotation transition behaving weirdly

阅读更多关于 D3 SVG transform rotation transition behaving weirdly

问题 I generated a geometric SVG pattern with D3 and I wanted to animate it. I wanted to have the circles and square spinning around their centre. However when they rotate the centre point moves along an elliptical path before returning to the correct position. My codepen is here: http://codepen.io/andybarefoot/pen/bwkjaN Clicking "spin" in the top left corner shows the unusual behaviour. My key function for rotating the "group" looks like this: function spinCircles() { d3 .select("#fixedGroup")

Update 6 : Fenomenas suggested me to re-create everything as simple as possible. I had my doubts that this would make any difference as the algorithm remains the same, and performance did not seem to be the issue. Anyway, it was the only suggestion I got so here it is: 30 FPS: http://www.feedpostal.com/test/simple/30/SimpleMovement.html 40 FPS: http://www.feedpostal.com/test/simple/40/SimpleMovement.html 60 FPS: http://www.feedpostal.com/test/simple/60/SimpleMovement.html 100 FPS: http://www.feedpostal.com/test/simple/100/SimpleMovement.html The code: package { import flash.display.Sprite;

CSS3 transform difference in Firefox and Chrome and IE

阅读更多关于 CSS3 transform difference in Firefox and Chrome and IE

问题 I think it may have something to do with a pseudo element, but I'm not sure. I am having difficulties with the effect of a transform transition using css3. In Firefox v24, the effect works as I want it to - see the CodePen here http://codepen.io/patrickwc/pen/aKEec but in Chrome and IE, the border effect of the links animate and then suddenly switch back into position. It is difficult to describe so the best way is to look at the effect in Firefox then in Chrome or IE. body { background: #000

Using D3 transition method with data for scatter plot

阅读更多关于 Using D3 transition method with data for scatter plot

So I'm new to D3 and have little exp with JavaScript in general. So I have been following some tutorials am currently using source code that creates a basic scatter plot. Now my question is how do I use the transition() method to moves the circles around when I add more datasets? I want to be able to set up buttons and when a user presses them, it activates the transition() method with the corresponding dataset. The tutorial I read on transitions only showed a transition on a single rectangle and did it manually, without data, and not with multiple items //Width and height var w = 900; var h =
