Total height of Stacked Bar on tip of every rectangle in stacked Bar Chart using d3

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");

Hightlight the respective layer in stacked Bar chart when mouseover on legend in d3

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 + ")");

D3 Scale domain does not update with selected data. I get negative values

I have a bar chart that updates based on the results selected in a drop-down menu. When I change the selcetion, I get negaitve "y" values. It seems that my domain does not get updated with the new data. When I hard code the domain, my "y" are what I expect them to be. Anyone knows why ? Any other other comments (formatting, etc) welcomed.

dept_3,d3_p1,5
dept_3,d3_p2,7
dept_3,d3_p3,10

Firgured out what was my problem. I hadn't defined the format of the values. The max function was returning the maximum number out of character values (9). I added the following piece of code prior to the domain function and everything now works fines.
csv_data.forEach(function(d) {
d.dept = d.dept;
d.Pos = d.Pos;
d.Value = +d.Value;
});

how to align y axis label in D3

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.

D3JS Axis orientation changes on data refresh

I have an issue on my bar/line chart whereby when data is refreshed, the left hand side Y axis has its tick marks change orientation from left to right. I am sure I have muddled up something simple as I am 4 days into D3, but I cannot see the problem.
My code is in JFIDDLE here. I have also added it to this post. Thank you for any assistance!

Your problem is in following two lines: (line number 492-493)
svg.select("g.y").call(yAxisL);
svg.select("g.y").call(yAxisR);
Your solution is to have two y axes two different classes, and you will achieve that by changing above lines to:
svg.select("g.y-l").call(yAxisL);
svg.select("g.y-r").call(yAxisR);
and also change
line 386 to:
.attr("class", "y-l axis")
line 397 to:
.attr("class", "y-r axis")
You need class names that are consistent.
