I want to create stacked bar chart with d3.
I have this data in CSV file:
Type Sum Color
Regular 29756.85897 green
Regular 9756.85897 blue
and I want that each row will appear above the other in Y axis.
for example in this photo, the blue area should start in y=9756 until y=39512.
what should I change?
this is the relevant html code:

I tried to use that stack function as you told me, and changed the attribute of "y" , but it's not work for me now. I think I did something wrong.

first of all, I guess that when you say
for example in this photo, the blue area should start in y=9756 until
y=39512
You actually mean
for example in this photo, the blue area should start in y=29756 until
y=39512
What happens is that your green area is painted from 0 to 29756 then your blue area on top of it from 0 to 9756. You need to shift each area on top of the previous one.
Easiest is to preprocess your data to do it.
D3.js can do it for you, see Stack Layout. This computes the y0 and y for all of your layers.
EDIT:
var stack = d3.layout.stack()
.x(function(d) { return d.Type }) // tell d3 to use Type as x value
.y(function(d) { return d.Sum }); // tell d3 to use Sum as y value
var stackData = stack(data);
After that, you data is augmented, i.e. each entry contains an additional y and y0 values that you can use directly to plot (in your y and height attribute).

I found a vertical stack bar graph sample on google - http://bl.ocks.org/juan-cb/43f10523858abf6053ae
I want to convert it in horizontal stacked bar graph. I have done the changes but something is wrong. Graph is not correct.I think all the bars are overlapped.
Please help me to resolve this. Code is copied.

A few minor things were missing/incorrect:
The group (<g>) containing the bars was being transformed incorrectly (I'm guessing you missed this while changing from vertical stacked to horizontal) i.e. the following line
.attr("transform", function(d) { return "translate(" + y(d.rooms) + ",0)"; });
translates the bar groups from the left and the y position would be 0 and hence the overlap. I've changed that to this:
.attr("transform", function(d) { return "translate(0, " + y(d.rooms) + ")"; });
The rects' x value is changed from x(d.y1) to x(d.y0) (might be a typo)
bar_enter.append("rect")
.attr("height", y.bandwidth())
.attr("x", function(d) { return x(d.y0); })
Axis padding was missing for the scaleBand(). I've added that (check docs for more info)
var y = d3.scaleBand()
.rangeRound([height, 0]).padding(0.1);
Reset the margins to adapt to the SVG dimensions:
var margin = {top: 10, right: 60, bottom: 60, left: 50},
Combining all of the above, here's a fork of your codepen:

You have to create the label :
var label = svg.append("text")
.attr("x", 4)
.attr("y", height)
.attr("dy", ".35em")
.text(function(d) { return "0"; });
Then add a transition on this new text
label.transition()
.attr("y", y(d.total) + 5)
.text(d.total);

You set a time scale in which the range uses padding and width:
var xScale = d3.time.scale()
.domain([mindate, maxdate])
.range([padding, width - padding * 2]);
Despite you had previously defined width:
width = 960 - margin.left - margin.right;
You didn't define padding anywhere in your code.
So, just give it any value you want, before defining the time scale:
var padding = 42; //tweak this value
How do I highlight an elliptical arc drawn, on mouseover and display tooltip on the same using d3.js?

Reference:
I have a simple bar chart here that should nicely transition all the bars over slightly to the left to make room for a new bar to appear on the right of the graph whenever new data is submitted via a button click event, however they all seem to fire over to the left side on top of each other.
Here is my code for my transition:
bars.transition()
.duration(1000)
.attr("x", function(d, i) {
return x(i);
})
.attr("y", function(d) {
return y(d.count);
})
.attr("width", x.rangeBand())
.attr("height", function(d) {
return height - y(d.count);
});
Here is a jsfiddle of the code so far: https://jsfiddle.net/foL2Lcg1/1/
The test data for entry on the button submission I'm using is 'Service: blah' and 'Count: 60000' which you can enter below the graph.
Any suggestions?
From the example here : https://bl.ocks.org/RandomEtc/cff3610e7dd47bef2d01
I have created this fiddle with your data : https://jsfiddle.net/thatOneGuy/foL2Lcg1/5/
I have added a draw function which you pass data. So instead of rewriting code as you were, you start by calling this function, and once you add/remove some data, you call this function again with the new set of data and it updates. Here is the function :
function draw(data) {
// measure the domain (for x, unique letters) (for y [0,maxFrequency])
// now the scales are finished and usable
x.domain(data.map(function(d) { return d.service; }));
y.domain([0, d3.max(data, function(d) { return d.count; })]);
// another g element, this time to move the origin to the bottom of the svg element
// someSelection.call(thing) is roughly equivalent to thing(someSelection[i])
// for everything in the selection\
// the end result is g populated with text and lines!
svg.select('.x.axis').transition().duration(300).call(xAxis);
// same for yAxis but with more transform and a title
svg.select(".y.axis").transition().duration(300).call(yAxis)
// THIS IS THE ACTUAL WORK!
var bars = svg.selectAll(".bar").data(data) // (data) is an array/iterable thing, second argument is an ID generator function
bars.exit()
.transition()
.duration(300)
.attr("y", y(0))
.attr("height", height - y(0))
.style('fill-opacity', 1e-6)
.remove();
// data that needs DOM = enter() (a set/selection, not an event!)
bars.enter().append("rect")
.attr("class", "bar")
.attr("y", function(d) {
return y(d.count);
})
.attr("height", function(d) {
return height - y(d.count);
})
// the "UPDATE" set:
bars.transition().duration(300).attr("x", function(d) { return x(d.service); }) // (d) is one item from the data array, x is the scale object from above
.attr("width", x.rangeBand()) // constant, so no callback function(d) here
.attr("y", function(d) { return y(d.count); })
.attr("height", function(d) { return height - y(d.count); }); // flip the height, because y's domain is bottom up, but SVG renders top down
}
Now update as you were on button click :
d3.select("button")
.attr("id", "submit")
.on("click", function() {
var service = document.getElementById("service").value;
var count = document.getElementById("count").value;
var json = {
"count": count,
"service": service
};
data.push(json);
draw(data)
})
Here is working code if fiddle isn't working :
var data = [
{
service: "QA",
count: "25262"
}, {
service: "QB",
count: "42386"
}, {
service: "QUERY_NOTICICATIONS",
count: "14042"
}, {
service: "TTL",
count: "4088"
}
];
// Mike Bostock "margin conventions"
var margin = {top: 20, right: 20, bottom: 30, left: 40},
width = window.innerWidth - margin.left - margin.right,
height = window.innerHeight/1.5 - margin.top - margin.bottom;
// D3 scales = just math
// x is a function that transforms from "domain" (data) into "range" (usual pixels)
// domain gets set after the data loads
var x = d3.scale.ordinal()
.rangeRoundBands([0, width], .1);
var y = d3.scale.linear()
.range([height, 0]);
// D3 Axis - renders a d3 scale in SVG

var yAxis = d3.svg.axis()
