    <p>There are a couple of small things that threw you off. First, the domain of the x0 scale should be an array of datetime objects, not an array of strings:</p> <pre><code>x0.domain(data.days.map(function(d) { var str = d.modified; d.date = parseDate( str.substring(0, str.length - 3) ); return d.date; })); </code></pre> <p>will return datetimes, not strings like it was before (minor nitpick: really not a fan of this use of <code>map</code>, I would add the date property separately in a forEach function as the data is loaded). </p> <p>Second, x0 needs to be passed a property that actually exists:</p> <pre><code>var state = svg.selectAll(".state") .data(data.days) .enter().append("g") .attr("class", "g") .attr("transform", function(d) { return "translate(" + x0(d.date) + ",0)"; }); </code></pre> <p>Before, you were using <code>x0(d.state)</code> which is a vestige from the grouped bar example (several others still exist; I've changed the minimum to get your project working). Since the value didn't exist, all of the rectangles were getting drawn over each other. </p> <p>Additionally, we need to format the axis labels so we aren't printing out the entire datetime object all over the labels:</p> <pre><code>var xAxis = d3.svg.axis() .scale(x0) .orient("bottom") .tickFormat(d3.time.format("%m-%d")); </code></pre> <p>Finally, I noticed that the newest dates were being printed on the left instead of the right. You could sort the results of <code>data.days.map( ... )</code> to fix that, I just reversed the range of x0: </p> <pre><code>var x0 = d3.scale.ordinal() .rangeRoundBands([width, 0], .1); </code></pre> <p><a href="https://github.com/1wheel/learning/tree/master/stacktest/D3.js%20graph%20displaying%20only%20one%20dataset" rel="nofollow">fixed files</a></p>

    1. COI think you'd need a `d3.time.scale` for real date objects, not just an ordinal scale...

    2. COx0 is an ordinal scale whose domain is an array of real data objects. I'm not sure if that is better than using a string to connect the scale to the data like you do though.

    3. COAhh, Thank you I was wondering how to flip the scale.

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.
