jquery - Setting Highcharts Series and Category data dynamically -

-

im trying update chart via ajax call using following code

$j(document).ready(function () {     $j("#filter").click(function () {         buildreport();     });      $j("#container").highcharts({         chart: {             type: 'column',             marginright: 130,             marginbottom: 100         },         title: {             text: 'ses open group',             x: -20 //center         },         yaxis: {             title: {                 text: ''             },             min: 0,             allowdecimals: false         },         xaxis: {},         tooltip: {             formatter: function () {                 return '<b>' + this.x + '</b><br/>' +                             this.series.name + ': ' + this.y + '<br/>' +                             'total: ' + this.point.stacktotal;             }         },         plotoptions: {             column: {                 stacking: 'normal',                 cursor: 'pointer',                 }             }         },         legend: {             layout: 'vertical',             align: 'right',             verticalalign: 'top',             x: -10,             y: 100,             borderwidth: 0         },         series: {}     });      buildreport(); });  function setchartseries(series) {     debugger;     chart = $j("#container").highcharts();     chart.xaxis[0].setcategories(getreportcategories(series));     chart.series = $j.map(series, function (item) {         return {             name: item.name,             color: item.colour,             data: $j.map(item.items, function (list) {                 return {                     name: list.category,                     y: list.value,                     id: list.id                 };             })         };     }); }  function getreportcategories(data) {     var catarray = [];     $j.each(data, function (index, value) {         $j.each(value.items, function (index, value) {             if ($j.inarray(value.category, catarray)) {                 catarray.push(value.category);             }         });     });      return catarray; }  function buildreport() {     $j.ajax({         url: "chartdatahandler.ashx",         datatype: "json",         cache: false,         success: function (data) {             setchartseries(data.series);         }     }); }

when page loads or filter button clicked buildreport calls handler , passes series data setchartseries. here can see chart properties set, chart never drawn. doing wrong?

if want create new series need use chart.addseries() method

if want set new data in existing series need use series.setdata() method.

as see, create new series each request , use addseries method

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...
