i trying create graph this:

http://bl.ocks.org/cmdoptesc/6228457

or this

http://raphaeljs.com/polar-clock.html

but want able scale (preferably without javascript) according browser width. love able css only, , if not css, preferably without library raphael or d3 (though i'll take can get). know how accomplish in way scales down / up?

update

i made js fiddle - graph want:

http://jsfiddle.net/q9hb5/

but need resize. using raphael, , read svg resizing here:

http://bertanguven.com/?tag=raphael-js

and here:

http://www.justinmccandless.com/blog/making+sense+of+svg+viewbox%27s+madness

but don't want have resize js - i'd able svg properties such viewbox , preserveaspectratio, still haven't seen example accomplishes this.

any ideas?

since don't want use javascript libraries, assume creating svg image ahead of time and/or on server, , transmitting static svg code user. canvas images, in contrast, made javascript.

(if want dynamically create graph javascript, not use library, hard part drawing graph, not getting resize! @lars kotthoff notes, javascript easy find out size of window , scale accordingly.)

to make svg scale , down, need include viewbox attribute on svg element, , scale automatically. warning, though, sizing image dynamically while maintaining aspect ratio can bit frustrating. preserveaspectratio attribute prevents distortion, leaving empty space, not scaling down. in firefox, using height:auto; cause svg height scale down match width , viewbox aspect ratio, not in webkit browsers.

example here:
http://fiddle.jshell.net/9dsbl/

a indirect solution + set svg height negligible (but not zero) amount, such 1px; + set overflow:visible; on svg; + use slice option preserveaspectratio, image scales larger dimension of height or width; + hard-code bottom padding style on svg element matches aspect ratio of viewbox; + wrap entire svg in <div> style overflow:hidden;.

html - Sizing a high-res image (~8MB) to display entirely in a small div (circular, diameter 100px) -

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
