and here link of graph_script.js

http://pastebin.com/fhqyxtsq

you can add formatter series so:

plotoptions: {             column: {                 datalabels: {                     enabled: true,                     formatter: function() {                         return '$' + this.y ;                                 }                 }             }         },

update : entire code should this;

<!doctype html> <html>      <head>         <title>graph 2</title>         <script type="text/javascript" src="jquery-1.7.2.min.js"></script>         <script type="text/javascript" src="graph_script.js"></script>     </head>     <body>         <div id="container" style="  height:285px; width:400px;float:left;margin:200px 0 0 335px; position:absolute;"></div>          <script type="text/javascript">              $(document).ready(function(){                var b;             b=17;             bb=17.60;             cc=21;             a=10;              var n=$;             var chart = new highcharts.chart(             {              chart: {                 renderto: 'container',                 defaultseriestype: 'column'             },             xaxis: {             categories: [''],             title: {                 text: '',                 style: {                    color: '#767575'                 }},             labels: {                     align: 'right',                     style: {                         font: 'normal 11px verdana'                     },                     x: 34,                 }},             yaxis: {                     min: 0,                     startontick: false,             labels: {                 formatter: function() {                     return this.value + '%';                         },             style: {                color: '#767575'             }},             title: {                 text: 'prevalence rate %',                 style: {                     color: '#767575'                 }}},             plotoptions: {                 column: {                     datalabels: {                         enabled: true,                         formatter: function() {                             return '$' + this.y ;                                     }                     }                 }             },             series: [                         {name: 'prevalence rate %', data: [b]},                          {name: 'prevalence rate %', data: [bb]},                          {name: 'prevalence rate %', data: [cc]},                         {name: 'prevalence rate %', data: [a]}                     ]                 });             });          </script>     </body> </html>

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
