    <p>In my controller I create the array to be charted </p> <pre><code>function chart() { $results = $this-&gt;Visit-&gt;query( "SELECT date(visits.created) as visit_date, Count(visits.id) AS count_visits FROM visits GROUP BY date(visits.created)" ); foreach($results AS $result) { $row = array( $result[0]['visit_date'], $result[0]['count_visits'] ); $chartData[] = json_encode($row); } pr($chartData); } </code></pre> <p>pr($chartData) gives following array</p> <pre><code>Array ( [0] =&gt; ["2012-07-11","5"] [1] =&gt; ["2012-07-13","1"] [2] =&gt; ["2012-07-14","1"] ) </code></pre> <p>in chart view i have </p> <pre><code>google.load('visualization', '1.0', {'packages':['corechart']}); google.setOnLoadCallback(drawChart); function drawChart() { // Create the data table. var data = google.visualization.arrayToDataTable($chartData); var options = { title: 'Visits by Date', hAxis: {title: 'Date', titleTextStyle: {color: 'black'}} }; var chart = new google.visualization.ColumnChart(document.getElementById('chart_div')); chart.draw(data, options); } </code></pre> <p>but this doesn't get me a chart .. no errors ... just no chart ..</p> <p>if I manually type in an array to test my view, it works fine ... eg if i replace .. </p> <pre><code>var data = google.visualization.arrayToDataTable($chartData); </code></pre> <p>with the following format from Google Chart example it generates a nice column chart</p> <pre><code> var data = google.visualization.arrayToDataTable([ ['Date', 'Count'], ['2012-07-11', 5], ['2012-07-13', 1], ['2012-07-14', 1] ]); </code></pre> <p>couple of questions: - how do i get the header titles in the var data array? - do double quotes or single quotes in array make a difference? - am i passing the array $chartData from php to Google chart javascript correctly? - the Google example has '[]' around the array, how do i get those around my array too? </p> <p>(bwt, i know all about cakephp's Find(all) but I just got lost in documentation about how to get what i wanted and sql was much easier )</p>

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.
