javascript - Crossfilter can't filter one dimension by another -


I am trying to filter two dimensions in Crossfilter. I have an array which repeats a given object: 

  { "bioguide_id": "O000167", "Prtham_nam": "Barack", "Last_Name": "Obama", " party ":" Democrat "," religion ":" United church of Christ "," Pisi_aidi ":" C -00404145 "," Pisi_nam ":" Mandokino county Democratic Central Committee "," Yogdan_kount ": 4," Yogdan_syuem " 1264, "Congress": 110}

I have the following query of a crossfilter working perfectly: 

  var yoga Dan = Data Dream (function (c) {return c. Contribution_user;}); Contribution (3) .for (function (p, i) {console.log (p.pac_name + "(" + p.congress + ")" + ": $" + p.contribution_sum);});

However, how can I get from Y Congress to top X contribution_sum ? You have not taken any advantage: 

  var congress = data.dimension (function (c) {return c.congress;}); Congress.filter (111) Group () Order (function (c) {return c.contribution_sum;}) Top (3) .for Ika (function (P, I) {console.log (p.pac_name + "(" + P.congress + ")" + ": $" + p.contribution_sum);});

Any thoughts on why?

I believe that you want to filter your 'Congress' dimension and then Ask for top members like your 'contribution_asam' dimension: 

  var congress = data.dimension (function (c) {return + c.congress;}); Var Contribution = Data Dream (function (c) {return + c.contribution_sum;}); Congress.filter (111); Contribution (3) .for (function (p, i) {console.log (p.pac_name + "(" + p.congress + ")" + ": $" + p.contribution_sum);});

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
