    <p>I'm having issue with generating arc curves with Raphael.</p> <p>I created a reduced example here: <a href="http://jsfiddle.net/vaxilart/m6cHw/3/" rel="nofollow">http://jsfiddle.net/vaxilart/m6cHw/3/</a></p> <p>As you can see, the first path drawn isn't the same as the second one, and the second one is only a subpath of the first.</p> <p>Do you know why both are different? And how could I resolve this issue?</p> <p>Here's the code:</p> <pre><code>function drawpath( canvas, bg, pathstr, duration, attr, callback ) { var guide_path = bg; var path = canvas.path( guide_path.getSubpath( 0, 1 ) ).attr( attr ); var total_length = guide_path.getTotalLength( guide_path ); var last_point = guide_path.getPointAtLength( 0 ); var start_time = new Date().getTime(); var interval_length = 50; var result = path; var run = function run() { var elapsed_time = new Date().getTime() - start_time; var this_length = elapsed_time / duration * total_length; var subpathstr = guide_path.getSubpath( 0, this_length ); path.attr({ path: subpathstr }); if ( elapsed_time &gt;= duration ) { if ( callback != undefined ) callback(); } else { requestAnimationFrame(run); } }; run(); return result; } var sequence_path = [ [ "M", 200, 0 ], [ "V", 200 ], [ "A", 100, 100, 90, 0, 0, 300, 300 ], [ "H", 400 ], [ "A", 100, -100, 90, 0, 0, 500, 400 ], [ "V", 500 ], [ "A", 100, -100, 90, 0, 0, 400, 600 ], [ "H", 200 ], [ "A", 100, 100, 90, 0, 0, 100, 700 ], [ "V", 800 ] ]; var paper = Raphael(10, 50, 700, 1000); var bg = paper.path(sequence_path).attr({ stroke: 'white', 'stroke-width': 64, 'stroke-opacity': 1, fill: 'none', 'fill-opacity': 0 }); drawpath( paper, bg, sequence_path, 3500, { stroke: 'orange', 'stroke-width': 64, 'stroke-opacity': 1, fill: 'none', 'fill-opacity': 0 }); </code></pre>

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.
