    <p>So first here's Fiddle of what I am trying to achieve in the end: <a href="http://jsfiddle.net/hQXvR/" rel="nofollow noreferrer">Fiddle</a></p> <p>To do so I need to get values from three different tables: ok_part, reject and stoppage.</p> <p>As for stoppage, the table structure looks like this:</p> <p><img src="https://i.stack.imgur.com/J0eZZ.jpg" alt="Stoppage table structure"></p> <p>The x Axis of my chart are one hour gaps, the first x Axis is always time 8 hours ago and the last one time from now to next full hour. </p> <p>I've managed to put together ok_part and reject arrays for highchart.</p> <pre><code>class GraphCalc() { ..... /* calculate time */ function CalculateTime($diff, $form) { $new = new DateTime(); $new-&gt;modify($diff); return $form != 0 ? $new-&gt;format('Y-m-d H:00') : $new-&gt;format('Y-m-d'); } function GraphInterval() { $time = strtotime($this-&gt;CalculateTime('-8 hours', 1)); // calling function to get time 8 hours ago $now = strtotime(date('Y-m-d H:00')); /* looping through time (8 hours ago to now) */ for ($i = $time, $j = $i + 3600; $i &lt;= $now; $i += 3600, $j += 3600) { /* puts together array for x Axis */ $this-&gt;xAxis_array[] = "'".date('H:00', $i).' - '.date('H:00', $j)."'"; /* queries to sum ok parts and rejects according to time */ $ok_part_sum[] = MouldingPart::find( array( 'select' =&gt; 'SUM(amount) as ok_qty', 'conditions' =&gt; array( 'moulding_product_id IN (?) AND date &gt;= ? AND date &lt;= ?', $this-&gt;product_id, date('Y-m-d H:00', $i), date('Y-m-d H:00', $j) ) ) )-&gt;ok_qty; $reject_part_sum[] = MouldingReject::find( array( 'select' =&gt; 'SUM(amount) as reject_qty', 'conditions' =&gt; array( 'moulding_product_id IN (?) AND date &gt;= ? AND date &lt;= ?', $this-&gt;product_id, date('Y-m-d H:00', $i), date('Y-m-d H:00', $j) ) ) )-&gt;reject_qty; } /* looping through ok_part and reject arrays to add 0 where there's no value */ for ($i = 0; $i &lt; count($ok_part_sum); $i++) { $this-&gt;chart_ok_array[] = $ok_part_sum[$i] == '' ? 0 : $ok_part_sum[$i]; $this-&gt;chart_reject_array[] = $reject_part_sum[$i] == '' ? 0 : $reject_part_sum[$i]; } } function xAxis() { /* return x Axis values */ return implode(', ',$this-&gt;xAxis_array); } function yAxisValues() { /* put together arrays for highchart */ $chart_data[] = "{data: [".implode(", ",$this-&gt;chart_ok_array)."], name: 'OK', color: '#89A54E'}"; $chart_data[] = "{data: [".implode(", ",$this-&gt;chart_reject_array)."], name: 'PRAAGID', color: '#AA4643'}"; return $chart_data; } } </code></pre> <p>I've would like help to get a solution for stoppage data. Stoppage has two dates that need to be considered: start_date and end_date. Based on the x Axis and stoppage dates I need to calculate the duration. Sometimes I could probably use the duration field, but I think it is easier to avoid it and just calculate it on the fly.</p> <p>Here's an example of what I would like to achieve with stoppage:</p> <p>Let's say x Axis is 05:00 - 06:00 then stoppage duration should be 59 minutes, because there is an entry in stoppage table with start_date 2013-09-05 05:01:00 and end_date 2013-09-05 09:00:00, but I can't use the end date of stoppage table value, because I need to use the x axis value which is 06:00.</p> <p>I hope you get an idea of what I am trying to achieve, it is really hard to explain it. </p> <p>The data in stoppage table might vary as well. In one hour there might be multiple stoppages. Let's say x Axis is 08:00 - 09:00 and in table there are three stoppages:</p> <p>start_date: 07:54 end_date: 08:15<br> start_date: 08:19 end_date: 08:38<br> start_date: 08:45 end_date: 09:47<br> So the duration from 08:00 - 09:00 should be 49 minutes.</p> <p>Please help me with this, I've been stuck with this for days now.. I tried to explain it as good as I could, but I bet it's still confusing.</p> <p>In the end I would like to get an array for highchart, like I have with ok_part and reject.</p>

    1. COYes, it's a bit confusing... You could try to make a picture (or whatever) of your desired chart maybe ? Do you always want the bars to be 100% ? Does your question is how to get an array with `php` of the `stoppage` series ?

    2. COI'm not sure I understood. So... are you trying to assemble some data into bins by time range, but you're having trouble because the stoppage table has already collected some data into different bins?

    3. COI think you want us to complete your `GraphInterval` function ?

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.
