jquery - Is there a callback for Twitter's Tweet Button? -

-

is there way register callback on twitter's tweet button? i'd able track particular users on site have tweeted link. can't add on onclick event because it's cross-domain iframe. other ideas?

i've seen one way it seems unreliable. their documentation doesn't mention looking work-around.

twitter has web intent events loaded, rendered, resize, tweet, follow, retweet, like, , click.

twttr.events.bind(   'tweet',   function (event) {     // there   } );

the behavior changed in fall of 2015 due unreliableness of callbacks happening after event complete.

they triggered when user invokes action in page, rather after action completed.

example loading widgets.js:

<script> // performant asynchronous method of loading widgets.js window.twttr = (function(d, s, id) {   var js, fjs = d.getelementsbytagname(s)[0],     t = window.twttr || {};   if (d.getelementbyid(id)) return t;   js = d.createelement(s);   js.id = id;   js.src = "https://platform.twitter.com/widgets.js";   fjs.parentnode.insertbefore(js, fjs);    t._e = [];   t.ready = function(f) {     t._e.push(f);   };    return t; }(document, "script", "twitter-wjs")); </script>  <script> // wait until twttr ready before adding event listeners twttr.ready(function (twttr) {   twttr.events.bind('tweet', function(event) {     console.log(event);   }); }); </script>

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
