    <p>I am fairly new to graphs using javascript and started using d3 and nvd3 for a project now. I am trying to plot a multi bar chart provided by nvd3 module. I am successful in plotting the data however, I am not able to customize the values for x axis for each series. I believe it is taking integer values for x to plot the graph. My question is how can I show some custom value like X, Y, Z instead of 1, 2, 3 for each graph. </p> <p>Below is my code i am using</p> <pre><code>var data = [{ "key" : "Step 1", "values" : [{"y" : 5,"x" : 2,},{"y" : 4,"x" : 1,}, {"y" : 4,"x" : 0,}] }, { "key" : "Step 2", "values" : [{"y" : 4,"x" : 0}, {"y" : 5,"x" : 2 }, {"y" : 6,"x" : 1 }] }, { "key" : "Step 3", "values" : [{"y" : 5,"x" : 2}, {"y" : 4,"x" : 0 }, {"y" : 5,"x" : 1 }] }]; var chart; var tickValues = ['X','Y','Z']; nv.addGraph(function() { chart = nv.models.multiBarChart().margin({ bottom : 100 }).transitionDuration(300).delay(0).groupSpacing(0.5); chart.multibar.hideable(true); chart.reduceXTicks(true).staggerLabels(true); chart.xAxis.showMaxMin(false) //.tickValues(tickMarks) .tickFormat(function(x){ return tickValues[x] } ); chart.yAxis.tickFormat(d3.format(',.1f')); d3.select('#chart1 svg').datum(data).call(chart); nv.utils.windowResize(chart.update); return chart; }); </code></pre> <p>if i plot the graph using the above code, the graph is generating properly but the Custom Values for X axis are completely out of order. I want X to be printed where value in data array hss x = 0, Y for data array x = 1 and so on. But right now its coming randomly.</p> <p>I tried passing the data as </p> <pre><code>var data = [{ "key" : "Step 1", "values" : [{"y" : 5,"x" : "Z",},{"y" : 4,"x" : "Y",}, {"y" : 4,"x" : "X",}] </code></pre> <p>So that I can plot the desired value of each axis as mention in data, but it does not work. :(</p> <p>Is there a better way to keep the values in sync ? Any help is highly appreciable. </p>

    1. CODo you have a fiddle or somewhere where we can view the code in action?

    2. COhttp://jsfiddle.net/VBtEx/ here is the code. I could not generate the graph because nvd3 is not hosted anywhere. I had to download the src code and added in my page. Thanks for your response.

    3. COI believe that you can't really do this with NVD3 -- it wasn't meant to support this. You would either have to modify the source code or start from scratch.

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.
