I drawn a stackedbar Chart in which now I trying to place the Total value(I mean the yaxis value) on tip of the every rectangle. I have coded to fetch the details but here the problem is I am getting Every Layer value on tip of every layer but i need to show only the last layer value.
the problem is shown in below fig's.
My code is Shown below

can anyone help me.
Here is what you need: First, we'll set fData as the data for the texts:
layer.selectAll("text.rect")
.data(fData)
.enter()
.append("text")
But, as this dataset doesn't have the correct yScale value, we'll have to extract it using a filter:
.attr("y", function (d) {
var filtered = fData.filter(function(e){
return e.Total_Units == d.Total_Units
});
return y(filtered[0].Total_Lines) - 3;
})
All together:
layer.selectAll("text.rect")
.data(fData)
.enter().append("text")
.attr("text-anchor", "middle")
.attr("x", function(d) {
return xScale(d.orders) + xScale.rangeBand() / 2;
})
.attr("y", function(d) {
var filtered = fData.filter(function(e) {
return e.Total_Units == d.Total_Units
});
return y(filtered[0].Total_Lines) - 3;
})
.text(function(d) {
return d.Total_Units
})
.style("fill", "4682b4");
Here is your fiddle: https://jsfiddle.net/wnwb6meh/
I have Done a stacked Bar chart now I am extending the Chart feature as when mouseover on the legend the Respective Bars should highlight.
The Problem I am facing is the mouseover event is working on the Last legend only but but highlighting the every rect layer in chart.
The Problem shown in below fig. This image is when I mouseover on D_Lines Legend Rect
My Code part is

Can any one help me to overcome this problem.
You are appending the same class : color-9999CC to all your rect elements, so once you hover the last legend item having color : #9999CC all rect element will be selected.
To create the required class properly, you can add the corresponding color info to each element in your layers object while creating it.
I added a color property that has as value the color of the corresponding headers item:
var layers = d3.layout.stack()(
headers.map(function (count) {
return fData.map(function (d,i) {
return { x: d.orders, y: +d[count] , color: colorScale(count)};
/*color = current headers item color */
});
}));
Then while creating your rect items you can add to each element a class by accessing its color property like this:
var rect = layer.selectAll("rect")
.data(function (d) { return d; })
.....
.attr("class", function (d) {
return "rect bordered " + "color-" +d.color.substring(1);
});
complete code:
var margin = {top:10, right: 10, bottom: 80, left: 50},
width =960,
height=650;
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 + ")");

i am trying to create a stacked bar graph.
however i can't seem to get the alignment right.the graph has two axis.
because of the length of the y axis label it is partially blocked.
i tried solving this by using different CSS styles on the label and on the enclosing div,
but they did not have the desired affect.
i created a jsfidel to explain my case.

i will appreciate any insight you have on this matter.
I cannot figure out why during the chart transitions in the attached JSFiddle the bars do not refresh properly.
If you click on "CLICK ME" a few times you will see that when DATA1 is selected (for example) bars for x values of 13 to 19 do not appear. I have three data sets that the chart randomly picks to use in refreshing itself, each with a different number of x-values.
Can someone help me understand please. Thank you in advance!

You need to handle the .enter() and .exit() selections in your update functions as well, as the data sets are of different size:
var sel = svg.selectAll(".bar") // change the bar
.data(data);
sel.exit().remove();
sel.enter().append("rect")
.on('mouseover', tip.show)
.on('mouseout', tip.hide)
.attr("class", "bar");
sel.transition().delay(function (d, i) {
return i / data.length * 1000;
})...

Full disclosure: I'm not new to programming, but I'm pretty new to d3 and javascript.
I am trying to combine the Grouped Bar Chart Example and the Sortable Bar Chart Example. I have a total of 51 groups of 3 variables. Here is a truncated form of my dataset you can use to run the code if you want:
State,Response,Predicted,Difference
1,0.0526,0.0983,0.0456
2,0.1161,0.1093,0.0068
5,0.0967,0.1035,0.0067
4,0.0998,0.0942,0.0055
6,0.0888,0.0957,0.0069
I want to be able to order the data by the Response variable by checking a box. Right now I can get the x-axis labels to move accordingly, but I can't get the bars to move with them. To get to this point I renamed the variables in the change() function according to my data. I tried saving the transition.selectAll(".state") function as state2 and then using state2.selectAll(".rect") to modify the x-coordinates of the rectangles, but I realized that wasn't going to get me anywhere.
Here is my code right now (mostly copied from the examples linked above). The relevant function is at the end.
var margin = {top: 20, right: 20, bottom: 30, left: 40},
width = 1000 - margin.left - margin.right,
height = 500 - margin.top - margin.bottom,
code = "";
var x0 = d3.scale.ordinal()
.rangeRoundBands([0, width], .1);
var x1 = d3.scale.ordinal();
var y = d3.scale.linear()
.range([height, 0]);
var color = d3.scale.category10();
var xAxis = d3.svg.axis()
.scale(x0)
.orient("bottom");
var yAxis = d3.svg.axis()
.scale(y)
.orient("left")
.tickFormat(d3.format(".0%"));
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 + ")");
d3.csv("data.csv", function(error, data) {
var ageNames = d3.keys(data[0]).filter(function(key) { return key !== "State"; });
data.forEach(function(d) {
d.ages = ageNames.map(function(name) { return {name: name, value: +d[name]}; });
});
x0.domain(data.map(function(d) { return d.State; }));
x1.domain(ageNames).rangeRoundBands([0, x0.rangeBand()]);
y.domain([0, d3.max(data, function(d) { return d3.max(d.ages, function(d) { return d.value; }); })]);

function change() {
clearTimeout(sortTimeout);
// Copy-on-write since tweens are evaluated after a delay.
var x2 = x0.domain(data.sort(this.checked
? function(a, b) { return b.Response - a.Response; }
: function(a, b) { return d3.ascending(a.State, b.State); })
.map(function(d) { return d.State; }))
.copy();
var transition = svg.transition().duration(750),
delay = function(d, i) { return i * 50; };
var state2 = transition.selectAll(".state")
.delay(delay)
.attr("x", function(d) { return x2(d.State); });
transition.select(".x.axis")
.call(xAxis)
.selectAll("g")
.delay(delay);
}
})
Any help would be greatly appreciated. I've found nothing so far searching SO and Google.
I assume that you want to keep the grouping when sorting. Your groups are contained in g elements, so all you need to do is adjust the coordinates of the groups. That is, the code to move the groups would look something like
svg.selectAll("g.g")
.transition().duration(750)
.delay(delay)
.attr("transform", function(d) { return "translate(" + x2(d.State) + ",0)"; });
Am tried with the stacked bar chart. To sort the stacked chart, please find the
Stacked Bar Chart
function change() {
// Copy-on-write since tweens are evaluated after a delay.
var x0 = x.domain(data.sort(this.checked
? function(a, b) { return b.noncomplete - a.noncomplete; }
: function(a, b) { return d3.ascending(a.moduleName, b.moduleName); })
.map(function(d) { return d.moduleName; }))
.copy();
var transition = svg.transition().duration(750),
delay = function(d, i) { return i * 60; };
transition.selectAll(".moduleName")
.delay(delay)
.attr("transform",function(d, i) { return "translate(" + (x0(d.moduleName)) + ",0)"; } );
transition.select(".x.axis")
.call(xAxis)
.selectAll("g")
.delay(delay);
}
