Using Highchart.js is it possible to add an image to a plotline label? Something as shown below <img src="https://i.stack.imgur.com/AOKAB.png" alt="enter image description here"> I want to add this (i) image along with a tooltip, but it seems (from <a href="http://api.highcharts.com/highcharts#yAxis.plotLines.label.text" rel="nofollow noreferrer">here</a>) that the limited set of html available for this elements does not support images, divs, or titles. I've figured that it would be easier to add this image and tooltip on a separated div (from graph), find the position of the label and use absolute positioning to add this layer. But I can't add any id or something to this element, so I can't find its position. Has someone had similar issues? My Solution: CSS <pre><code>.infoMedia { position: absolute; z-index : 10000; width: 30px; height: 30px; background: url('../img/information.png') center no-repeat; } </code></pre> HTML <pre><code><div class='infoMedia' style='left:0px;top:0px;'></div> </code></pre> javascript <pre><code>function processHintPosition() // every resize, call this function { $('.infoMediaENEM').css('top', 0); $('.infoMedia').css('left', 0); var this_container = $('#container_line_graph'); var this_container_width = $(this_container).width(); var this_container_height = $(this_container).height(); var this_margin_y = 60; var this_margin_x = 15; $('.infoMedia').css('top', $(this_container).offset().top + $(this_container).height() - this_margin_y); // POSITION X var x_val = $(this_container).offset().left + this_container_width - this_margin_x; $('.infoMedia').css('left', x_val) // POSITION Y var this_media = parseFloat(lineGraph.linechart_data.prcMedia); var this_max = 100; var this_val_posy = Math.ceil( ( this_media * (this_container_height - this_margin_y) ) / this_max ); var y_val = (($('.infoMedia').offset().top) - this_val_posy) - ($('.infoMedia').height()/2); $('.infoMedia').css('top', y_val); } </code></pre>

Guidance

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.
