I'm trying to get day of the month(i.e 1,2,3,4 ...etc) on the x axis and time period of the hour 0-24 on Y axis. I am unable to get the axis line i dont know why.Can someone tell me why? In the console window, it says padding is not defined.

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

I am trying to get my d3 bar graph to update with a csv and for some reason I keep getting the error that data is undefined when I run it with the live server extension, however I am not sure why because it works totally fine with a different csv. Earlier I was having a different error with this code where it would show up but only one bar would be filled in all the way to the top no matter what was selected from the dropdown. Any help would be greatly appreciated!! Here is my code:

I am plotting a bar chart in D3.js (Version 3). Which has two axis, one is receive_data and another one is responses. I have a JSON file where I stored the data. JSON format looks like,
[{"receive_date":"2013-11-04","responses":"2"}]
In my JSON, I have two responses values for the same date 2013-11-04 .
Like,
[{"receive_date":"2013-11-04","responses":"2"},{"receive_date":"2013-11-04","responses":"8668"}
This is the JSON Source :- https://api.myjson.com/bins/gdpu7
So, when I am plotting the graph, it is not taking the sum of the values for the same receive_date instead it is showing two times. I want it to show the sum of responses. responses should be (8668+2) for the receive_date 2013-11-04
I also found it that by using reduce we can do this. I tried to use d3.json.reduce . But it is showing error d3.json.reduce is not a function.

The data with which I want to work is a csv file and looks like this:
Age, ZNF8, ZNF18, ZNF136, ZNF140 .... ZNF778,
"8pwc", 13.654, 12.643, 10.593, 8,124, .... 9.900,
"9pwc", 4.364, 1.004, 3.576, 0.032, .... 5.512,
"2yrs", 65.345, 53.278, 33.001, 68.844, .... 54.544,
....
Thank you!
In this particular case, you have to use a point scale, which is a type of ordinal scale:
Point scales are a variant of band scales with the bandwidth fixed to zero. Point scales are typically used for scatterplots with an ordinal or categorical dimension.
A point scale will allow you to map a categorical (qualitative) variable to a continuous numeric output.
Thus, your scale should be:
var x = d3.scalePoint().range([0, width])
And its domain should be defined with a map:
x.domain(data.map(d=>d.Age));
Here is the working code: https://plnkr.co/edit/2nOLP5fEIHbs2U8OQB2y?p=preview
This is a question already asked, but none of the solutions worked for me so putting up again.
1.I am trying to change the color of the bar in my D3 bar chart, based on a certain threshold value(if the bar exceeds a particular value on the y axis say 30 in this case) How can I change the color of the bar to something else say blue.
I also want to draw a horizontal line at y= 30.

Any reason not to do the obvious:
svg.selectAll(".bar")
.data(data)
.enter().append("rect")
.attr("class", function(d) {d.frequency < threshold ? 'bar' : 'bar bar-special';})
etc.
As #Stephen told you can basically make use of the class attribute to manage the color of your bars. Another approach is to use the fill attribute and use a function to return the desired value.
svg.selectAll(".bar")
.data(data)
.enter().append("rect")
.attr("class", "bar")
.attr("x", function(d) { return x(d.letter); })
.attr("width", x.rangeBand())
.attr("y", function(d) { return y(d.frequency); })
.attr("height", function(d) { return height - y(d.frequency); })
.attr("fill", function(d) {
if (d.frequency >= 30) {
return 'red';
}
return 'green';
});
As for the line you want to draw you might do something like this:
svg.append("line")
.attr("x1", 0)
.attr("y1", y(30))
.attr("x2", width)
.attr("y2", y(30))
.style("stroke", "#828282")
.attr('stroke-dasharray', '2,2')
.attr('stroke-width', '1')
Here is a plunker with code similar to yours: https://plnkr.co/edit/3danSMezWDsbnJZXEUTH?p=preview
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?

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).
