Body
<p>You should use a associative array instead of an array, so that you can look up the data based on the name as a string instead of trying to find the variable. All objects in Javascript are associative arrays, so just put the data in an object.</p> <p>Also:</p> <ul> <li>Create the <code>mygraphs</code> array inside the event handler, otherwise it can not shrink when you uncheck options.</li> <li>Catch the click on the checkboxes inside the form, not on the form itself.</li> <li>Put a <code>label</code> tag around the checkbox and it's label, that way the label is also clickable.</li> <li>You don't need an index variable to put values in the <code>mygraphs</code> array, just use the <code>push</code> method to add items to it.</li> </ul> <p><a href="http://jsfiddle.net/cCukJ/" rel="nofollow">http://jsfiddle.net/cCukJ/</a></p> <p>Javascript:</p> <pre><code>$(function() { Comment = [['2011-01-29',7695],['2011-02-02',19805]]; WallPost = [['2011-01-29',11115],['2011-02-02',8680]]; Likes = [['2011-01-29',5405],['2011-02-02',10930]]; var seriesre = { 'Comment': Comment, 'WallPost': WallPost, 'Likes': Likes }; $("#testCheck :checkbox").click(function() { var mygraphs = []; $("#testCheck :checked").each(function() { mygraphs.push(seriesre[$(this).val()]); }); alert("["+mygraphs+"]"); }); }); </code></pre> <p>HTML:</p> <pre><code><div class="activity"> <form method="POST" id="testCheck" name="myform"> <label> Likes <input type="checkbox" value="Likes" name="box2"> </label> <label> Comments <input type="checkbox" value="Comment" name="box3"> </label> <label> Wall Post <input type="checkbox" value="WallPost" name="box4"> </label> </form> </div> </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.
