jquery - get json data in controller action in asp.net mvc -

-

i have asp.net mvc application. want configure object in jquery , want pass the action of controller . in script using configure data ajax call:

var arr=new array();  arr.push(0)=1; arr.push(1)=2; arr.push(2)=3;  var  peform = {                  empid: eid,                  depatrmentid:deptid,                  empaddress:straddress,                  empbirthdate:bdate,                  empaccountsid:arr               };

i able values in param here but. when trying this:

if(peform!=null)             {                   var json = $.tojson(peform);                   $.ajax({                  url: '/load/savedata',                  type: 'post',                  datatype: 'json',                  data: json,                  contenttype: 'application/json; charset=utf-8',                  success: function (data) {                  }         });    }

it not calls action in controller. think here :

 var json = $.tojson(peform);

is not working expect. need add js file reference ? or mistake in syntax? or please suggest me other remedy.

try following instead: 

var json = json.stringify(peform);

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....
