问题 I'm trying to plot streaming data in matplotlib. I can update the plot using interactive mode and the set_ydata function. It animates and everything looks good until the loop ends. Then the python kernel crashes and I get this message: C:\Conda\lib\site-packages\matplotlib\backend_bases.py:2437: MatplotlibDeprecationWarning: Using default event loop until function specific to this GUI is implemented warnings.warn(str, mplDeprecation) Here's the code: import numpy as np import matplotlib

jQuery animate lineHeight - relative property gives weird result

阅读更多关于 jQuery animate lineHeight - relative property gives weird result

问题 I am trying to increase the font size within a page and therefore also adjust the line height accordingly. Now I saw that I can use relative values for the font-size, but somehow this doesn't work for the line-height!? $('elem').on('click', function () { box.animate({ 'lineHeight': '+=5', 'fontSize': '+=5' }); }); Is there another way then: var lh = parseFloat( box.css('line-height'), 10); $('elem').on('click', function () { lh += 5; box.animate({ 'lineHeight': lh + 'px', 'fontSize': '+=5' })

Trigger animation when div element appears in viewport

阅读更多关于 Trigger animation when div element appears in viewport

问题 I am using a scroll trigger from this answer to build a progressbar.js animation that is triggered once the entire progress bar div is in the viewport. The animation works normally with no trigger, it just runs on page load. But I can't make it trigger when the element scrolls into full view. The example code below has a div gap at the top so you can scroll down before the animation starts, although that is obviously the part I cannot get working. function privacyScoreCircle() { //

Shrink/Grow animation using jQuery/CSS

阅读更多关于 Shrink/Grow animation using jQuery/CSS

问题 How can a grow/shrink animation be done with jQuery and/or CSS? An example that I can think of is this when you click on the Join Now button. I looked into animate.css but they did not offer such an animation. 回答1: DEMO — Solution using CSS3's transition-duration (W3Schools) and transform:scale(X,Y); (W3Schools). Update: DEMO — Going a step further, doing more than just changing to opacity:0; by adding display:none; (via jQuery .hide() ) at the end of the animation. 来源： https://stackoverflow
