    <p>I am just starting out with cubism.js</p> <p>Stripping down the example code I am able to show two metrics .. one calculated (kpi1) -- random function , one from Cube (kpi2). It works perfect at a context step of 1e4 as soon as I change it to 1e3 the calculated one - random - shows fine at a resolution of 1s while the one from Cube does not show at all.</p> <p>this works:</p> <pre><code>var context = cubism.context() .serverDelay(0) .clientDelay(0) .step(1e4) .size(960); </code></pre> <p>this does not:</p> <pre><code>var context = cubism.context() .serverDelay(0) .clientDelay(0) .step(1e3) .size(960); </code></pre> <p>What am I doing wrong?</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html&gt;&lt;head&gt;&lt;meta http-equiv="content-type" content="text/html; charset=UTF-8"&gt;&lt;meta charset="utf-8"&gt; &lt;title&gt;Dashboard&lt;/title&gt; &lt;/head&gt;&lt;body&gt;&lt;div id="body"&gt; &lt;div id="kpi1"&gt;&lt;/div&gt; &lt;div id="kpi2"&gt;&lt;/div&gt; &lt;script src="../d3.v2.js"&gt;&lt;/script&gt; &lt;script src="../cubism.v1.js"&gt;&lt;/script&gt; &lt;script&gt;function random(name) { var value = 0, values = [], i = 0, last; return context.metric(function(start, stop, step, callback) { start = +start, stop = +stop; if (isNaN(last)) last = start; while (last &lt; stop) { last += step; value = Math.max(-10, Math.min(10, value + .8 * Math.random() - .4 + .2 * Math.cos(i += .2))); values.push(value); } callback(null, values = values.slice((start - stop) / step)); }, name); }&lt;/script&gt; &lt;script&gt; var context = cubism.context() .serverDelay(0) .clientDelay(0) .step(1e4) .size(960); var foo = random("foo"); var cube = context.cube(); d3.select("#kpi1").call(function(div) { div.selectAll(".horizon") .data([foo]) .enter().append("div") .attr("class", "horizon") .call(context.horizon()); }); d3.select("#kpi2").call(function(div) { div.selectAll(".horizon") .data([cube.metric("median(cube_compute(ms))")]) .enter().append("div") .attr("class", "horizon") .call(context.horizon()); }); &lt;/script&gt; &lt;/body&gt;&lt;/html&gt; </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.
