    <p>I need to make a scatter plot for some categorical data for rainfall in 3 cities for 3 years using d3.js:</p> <pre><code>Year1 Year2 Year3 NY CA TX NY CA TX NY CA TX 17 20 15 23 10 11 14 15 17 16 18 12 15 21 22 20 18 19 13 22 16 17 25 18 17 25 18 19 18 13 16 21 20 22 15 16 </code></pre> <p><img src="https://i.stack.imgur.com/XCQqX.png" alt="This is how the graph should look like"> (Note: the data and plot do not match here, it is just to explain my query) I am completely new to d3.js. I have attempted some tutorials for simple scatterplots and bar graphs, but I can't figure out how do I display a categorical graph like this one.</p> <p>Any help to get me started would be appreciated.</p> <p>[edit] I rearranged the data in the tsv file so it looks like this:</p> <pre><code>year state rain 1 NY 17 1 NY 16 1 NY 13 1 CA 20 1 TX 15 2 NY 23 3 CA 10 3 TX 14 3 NY 13 </code></pre> <p>There seems to be some problem. I get "Unexpected value NaN parsing cx attribute." and same for cy. Any idea how can I fix it?</p> <pre><code>var newArray = new Array(); // draw the scatterplot svg.selectAll("dot") // provides a suitable grouping for the svg elements that will be added .data(data) // associates the range of data to the group of elements .enter().append("circle") // adds a circle for each data point .attr("r", 5) // with a radius of 3.5 pixels .attr("cx", function (d) { newArray = data.filter( function (el) { return el.category == "NY"; }); return xScale(newArray.rain); }) // at an appropriate x coordinate .attr("cy", function (d) { return yScale(newArray.year); }) // and an appropriate y coordinate .style("fill", color(9)); </code></pre>

    1. COThe [NVD3 scatterplot](http://nvd3.org/ghpages/scatter.html) is probably a good place to start.

    3. CONVD3 is based on D3. I can't really help you unless you show us the complete code.

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.
