    <p>I made something for it. The solution involves custom painting over the highlight canvas.</p> <p><a href="http://jsfiddle.net/Boro/CxsXk/" rel="nofollow noreferrer">The sample is here.</a></p> <p>It was integrated into a sample I made for a question asking how to add sums on top of a stacked bar chart, <a href="https://stackoverflow.com/a/10688315/613495">details are here</a>. I also upgraded its code, so now it is 'bar chart orientation friendly'.</p> <p>Just in case the JS code is also below:</p> <pre><code>$(document).ready(function() { var ins = [2, 2, 3, 5]; var outs = [2, 4, 3, 5]; var swaps = [2, 2, 6, 5]; var passes = [2, 4, 6, 5]; var data = [ins, outs, swaps, passes, [3, 3, 3, 3]]; var series = [ { label: 'IN', pointLabels: { labels: [2, 2, 3, 5] }}, { label: 'OUT', pointLabels: { labels: [2, 4, 3, 5] }}, { label: 'SWAP', pointLabels: { labels: [2, 2, 6, 5] }}, { label: 'PASS', pointLabels: { labels: [2, 4, 6, 5] }}, { label: 'INVISIBLE', pointLabels: { labels: ['∑ 8', '∑ 12', '∑ 18', '∑ 20'] }, show: false, shadowAngle: 90,//for horizontal use (180 istead of 90) rendererOptions: { shadowDepth: 25, shadowOffset: 2.5, shadowAlpha: 0.01 }} ]; var ticks = ['Oi', 'Bike', 'Car', 'Truck']; var plot = $.jqplot('chart', data, { stackSeries: true, seriesDefaults: { renderer: $.jqplot.BarRenderer, rendererOptions: { barMargin: 20 //for horizontal uncomment this // ,barDirection: 'horizontal' }, pointLabels: { show: true, stackedValue: false, location: 's' } }, axes: { xaxis: { renderer: $.jqplot.CategoryAxisRenderer, ticks: ticks } //for horiozontal use the below instead /* yaxis: { renderer: $.jqplot.CategoryAxisRenderer, ticks: ticks } */ }, legend: { show: true, location: 'ne', placement: 'outside' }, series: series, title: "Oi title" });

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.
