    <p>I am in my rookie stage learning javascript. I made an API that gets a number of users registered on a certain date and returns this data as a JSON object. Here is a sample of that data</p> <pre><code>{"myjsonobject": [{"users": 3, "joined": "2013-05-25"}, {"users": 1, "joined": "2013-05-26"}, {"users": 1, "joined": "2013-05-30"}, {"users": 1, "joined": "2013-05-31"}]} </code></pre> <p>I then parse the data and graph on <a href="http://www.chartjs.org" rel="nofollow">ChartJS</a> linegraph using the javascript function below</p> <pre><code>$(document).ready(function() { url = "http://mylink/getjson/" Create_jsonObject(url) }); function Create_jsonObject(url) { $.getJSON(url, function (data) { myJSONObject=data; var dataSource=myJSONObject.myjsonoject; var chart = $("#chartContainer").dxChart({ dataSource: dataSource, commonSeriesSettings: { argumentField: 'joined' }, series: [ { valueField: 'users', name: 'users' }, ], argumentAxis:{ grid:{ visible: true } }, tooltip:{ enabled: true }, title: 'Volunteer Registration', legend: { verticalAlignment: 'bottom', horizontalAlignment: 'center' }, commonPaneSettings: { border:{ visible: true, right: false } } }); }); }; </code></pre> <p>The function works in charting the JSON data on the linegraph. I would like to incorporate a javascript function that checks for missing dates and inserts 0 users where a date is missing. Thus the graph will plot zero where not date was returned. It should check this against the earliest date returned. Any ideas anyone? </p> <p>Thanks</p>

    1. COso you want this to return false {"myjsonobject": [{"users": 3]} , but not this {"myjsonobject": [{"users": 3, "joined": "2013-05-25"}, {"users": 3}]} ?

    2. COWhy not make json at server side only with missing date logic and provide it to Charts API. Why doing extra work at client side?

    3. CONo. I would like the JSON object to remain as it is but in the event a date is missing, it should append a 0. For example {"myjsonobject": [{"users": 3, "joined": "2013-05-25"},{"users": 0, "joined": "2013-05-26"}, {"users": 2, "joined": "2013-05-27"}]}

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.
