javascript - D3 is attempting to set attributes of SVG as NaN and I can't figure out why -


i'm trying make basic d3 charts, have little experience doing. here sample of json working (i have 100 objects, left out brevity):

var data = [             {                "orderid": 1,                "shipcountry": "usa",                "freight": 168.0,                "version": 2            },            {                "orderid": 2,                "shipcountry": "usa",                "freight": 336.0,                "version": 2            },            {                "orderid": 3,                "shipcountry": "usa",                "freight": 504.0,                "version": 2            }]

and here d3 code:

 var margin = { top: 10, bottom: 30, left: 30, right: 20 };  var width = 700 - margin.left - margin.right; var height = 400 - margin.top - margin.bottom; //svg chart margins var svg = d3.select('#chart-wrapper')                 .append('svg')                     .attr('height', height + margin.top + margin.bottom)                     .attr('width', width + margin.left + margin.right)                 .append('g')                     .attr('transform', 'translate(' + margin.left + ',' + margin.top + ')');  //xscale based on orderid attribute var xscale = d3.scale.linear().domain([0, 99]).range([0, width]); var yscale = d3.scale.linear().domain([16632, 0]).range(height, 0);     svg.selectall('circle')     .data(data)     .enter()     .append('circle')         .attr('cx', function (d) {             return xscale(d.freight)         })         .attr('cy', function (d) {             return yscale(d.orderid);         })         .attr('r', 2)         .attr('fill', 'green');

for reason, cy property of each circle gets set nan- keeps rendering. have switched around freight , orderid fields, , still cy property not set correctly. while debugging, have logged values of each, , appear real numbers. (this happened while trying create line graph- second number of 'd' attribute path nan, when decided attempt scatterplot instead)

any idea going on? thanks

you need make argument .range() array.

var yscale = d3.scale.linear().domain([16632, 0]).range(height, 0);

is now

var yscale = d3.scale.linear().domain([16632, 0]).range([height, 0]);

asynchronous - Python asyncio task got bad yield -

i confused how play around asyncio module in python 3.4. have searching api search engine, , want each search request run either parallel, or asynchronously, don't have wait 1 search finish start another. here high-level searching api build objects raw search results. search engine using kind of asyncio mechanism, won't bother that. # no asyncio module used here class search(object): ... self.s = some_search_engine() ... def searching(self, *args, **kwargs): ret = {} # raw searching according args , kwargs , build wrapped results ... return ret to try async requests, wrote following test case test how can interact stuff asyncio module. # here testing script @asyncio.coroutine def handle(f, *args, **kwargs): r = yield f(*args, **kwargs) return r s = search() loop = asyncio.get_event_loop() loop.run_until_complete(handle(s.searching, arg1, arg2, ...)) loop.close() by running pytest, return runtimeerror: task got bad yield : {results s...

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
