    <pre><code>$.jqplot.eventListenerHooks.push(['jqplotClick', myClickHandler]); </code></pre> <p>This call will attach onClick handler to the whole event canvas. (This event canvas is with the size of the plot and should be ABOVE all other canvases to work - meaning that you might need to manually modify it's z-index to make things work). What I think is happening in your case is this:</p> <ol> <li><p>You are attaching "myClickHandler" method to the event canvas. It will be fired every time event canvas is clicked, no matter where - over the series or over the background of the plot.</p></li> <li><p>In the case with barchart renderer this event canvas is below the series canvas (either it is created before series canvas, or it has lower z-index). Solution would be to manually increase the z-index of the event canvas AFTER chart was created. After this it will be on top and click events will be handled correctly.</p></li> <li><p>Remember, this click event will fired on every click over the plot, no matter where. Solution would be to filter the execution of the "myClickHandler" method like this:</p></li> </ol> <p>Code:</p> <pre><code>function myClickHandler(ev, gridpos, datapos, neighbor, plot) { if (isClickEventOverTheSeries(gridpos)) { alert('you have triggered click action'); } } </code></pre> <p>In this example <strong><em>gridpos</em></strong> is array which contains 2 points - x and y coordinates of the click event. "<strong>isClickEventOverTheSeries</strong>" method is function which checks if under this coordinates there is series drawn. I'm not sure how to achieve this with BarChart renderer - I never used it, but with the line render there is a method which checks it...</p> <p>Hope this helps</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.
