    <p>When I am using this data structure from a javascript source file:</p> <pre><code>var data = [{'x': 100, 'y': '65'}, {'x': 122, 'y': '57'}, {'x': 144, 'y': '101'}, {'x': 166, 'y': '87'}, {'x': 188, 'y': '8'}, {'x': 210, 'y': '180'}, {'x': 232, 'y': '132'}, {'x': 257, 'y': '190'}, {'x': 276, 'y': '210'}, {'x': 298, 'y': '150'}] </code></pre> <p>and <code>alert</code> the data in my main file it shows:</p> <pre><code>[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object] </code></pre> <p>also it works fine with :</p> <pre><code>alert(d3.max(data,function(d) { return d.count;})) </code></pre> <p>But when I using a python as a source file and returns this :</p> <pre><code> data = [{'x': 100, 'y': '65'}, {'x': 122, 'y': '57'}, {'x': 144, 'y': '101'}, {'x': 166, 'y': '87'}, {'x': 188, 'y': '8'}, {'x': 210, 'y': '180'}, {'x': 232, 'y': '132'}, {'x': 257, 'y': '190'}, {'x': 276, 'y': '210'}, {'x': 298, 'y': '150'}] abc=json.dumps(data) print data </code></pre> <p>The alert shows also the same:</p> <pre><code>[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object] </code></pre> <p>But this does not work:</p> <pre><code>alert(d3.max(data,function(d) { return d.count;})) </code></pre> <p>Here is my entire code</p> <pre><code>function add_py() { var count = $( "#count" ).val(); $.ajax({ type: "get", url: "abc.py", data: {'count': count}, datatype:"script", async: false, success: function(response) { var data= JSON.parse(response); showGraph(data); }, // success closed error:function(xhr,err) { alert("Error connecting to server, please contact system administator."); } })//ajax closed } function showGraph(de) { alert(de) var mySVG = d3.select("body").append("svg"); mySVG .attr("width", 500) .attr("height", 500); var heightScale = d3.scale.linear() .domain([0, 963]) .range([0, 400]); alert(d3.max(de,function(d) { return d.count;})) var heightScale = d3.scale.linear() .domain([0, d3.max(de,function(d) { return d.count;})]) .range([0, 400]); var myBars = mySVG.selectAll('circle') .data(de) .enter() .append('svg:circle'); myBars .attr('r',20); myBars .attr('cx',function(d,i) {return (i * 22) + 100;}) .attr('cy',function(d,i) {return 400 - heightScale(d.count);}); } </code></pre> <p>I understand a data from js and from python file may behave differently , but how to make python data working same like js data. Thanks in advance.</p>

    2. COYou have number values for `x` and strings for `y`: it could help if you change them to numbers.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
