    <p>I am new to D3 and trying to learn a few basics. I've been using the D3 tips and Tricks book and tried to adapt a line graph to get a couple of lines into it which both transition. The basic idea is that Line A starts off with Data A, Line B with Data B. Then on clicking a button, Line A transitions to Data C and Line B to Data D. </p> <p>The line graph is an over time graph so I've set the x axis to be a time axis. </p> <p>Here's the code I'm using (cut down a bit)</p> <pre><code> // Define the axes var xAxis = d3.svg.axis().scale(x) .orient("bottom").ticks(10); var yAxis = d3.svg.axis().scale(y) .orient("left").ticks(5); // Define the line var valueline = d3.svg.line() .x(function(d) { return x(d.date); }) .y(function(d) { return y(d.number); }); // Define the line var valueline2 = d3.svg.line() .x(function(d) { return x(d.date); }) .y(function(d) { return y(d.number2); }); // Define the line var valueline3 = d3.svg.line() .x(function(d) { return x(d.date); }) .y(function(d) { return y(d.number3); }); // Define the line var valueline4 = d3.svg.line() .x(function(d) { return x(d.date); }) .y(function(d) { return y(d.number4); }); // Adds the svg canvas var svg = d3.select("body") .append("svg") .attr("width", width + margin.left + margin.right) .attr("height", height + margin.top + margin.bottom) .append("g") .attr("transform", "translate(" + margin.left + "," + margin.top + ")"); // Get the data d3.tsv("data/data3.tsv", function(error, data) { d.date = parseDate(d.date); d.number = +d.number; d.number2 = +d.number2; d.number3 = +d.number3; d.number4 = +d.number4; d.number5 = +d.number5; }); // Scale the range of the data x.domain(d3.extent(data, function(d) { return d.date; })); y.domain([0, d3.max(data, function(d) { return d.number4; })]); // Add the path. svg.append("path") .attr("d", valueline(data)); //Add the transition for the first line d3.select("p2") .on("click", function() { svg.select("path") .data(data) .transition() .delay(function(d, i) { return i / 40 * 1000; }) .duration(1500) .attr("d", valueline3(data)); }) ; // Add the second path. svg.append("path") .attr("d", valueline2(data)) //Add the transition for the second line d3.select("p3") .on("click", function() { svg.select("path") .data(data) .transition() .delay(function(d, i) { return i / 40 * 1000; }) .duration(1500) .attr("d", valueline4(data)); }) </code></pre> <p>The problem is that oth transitions end up applying to the first line, with the second one static What am I doing wrong? </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.
