    <p>I am working on a d3.js project where I am displaying a number of rectangles to be the same height. The rectangles are connected to a <code>input[type=number]</code> that adjust the height of each group of rectangles. To make animation easier (so I only have to manipulate the <code>svg:defs</code> onchange of the number input), I would like to be able to specify the height of a group of rectangles with a <code>svg:def</code> tag like this:</p> <pre class="lang-js prettyprint-override"><code>var svg = d3.select("body").append("svg") .attr("width", 960) .attr("height", 500); svg.append("defs").selectAll(".rectdef") .data(data).enter() .append("rect") .attr("class", "rectdef") .attr("id", function (d, i){return "rect" + d.name;}) .attr("x", 0) // overridden below .attr("width", 0) // overridden below .attr("y", 0) // overridden below .attr("height", function (d, i){return d.height}); </code></pre> <p>and then to be able to just refine placement x, y and width of the rectangles with something like this:</p> <pre class="lang-js prettyprint-override"><code>svg.selectAll(".bar") .data(data).enter() .append("use") .attr("class", "bar") .attr("xlink:href",function (d){return "#rect"+d.type;}) .attr("x", function(d) { return d.x }) .attr("width", function (d) {return d.w;}) // this does NOT adjust width! .attr("y", function (d) {return 0;}); </code></pre> <p>This snippet correctly changes the x and y coordinates but it does not properly change the width! Any ideas what's wrong here? Is this a browser issue (I'm using Chrome 24.0.1312.52)? Is width not editable like this on an svg:use tag?</p> <p>There aren't any problems with the data (I've checked that) and I have been able to confirm that the animation does work correctly.</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.
