d3 show labels only for ticks with data in a bar chart

Question

First, I\'m new with D3. :) I have a stacked bar chart. My y axis is a ordinal scale (state). In my data, I could have total=0 for some ticks. So, I just want to see the lab

You can use .tickFormat() to suppress the labels for those particular values. As the thing you want to check isn't part of the data that's available to the scale, you'll need to find it in your entire data:

yAxis.tickFormat(function(d) {
    var val = 0;
    dataSet.forEach(function(item) {
        if(item.Date == d) val = item.total;
    });
    return val == 0 ? "" : d;
});

This will suppress the label (return "") if the total is 0 or the value can't be found in the data set. Complete demo here.
