I'm new to D3.js. I have two problem while creating line chart in D3.js.
One is, I have tried to create line chart in D3.js using the following input values. In my output graph X-axis, I didn't get the time along with date which is present in the input file. I didn't understand how do date parsing into some format happening while creating graph. I don't know how to parse the date into some format to get date with time in my graph x-axis.

My output graph:
Instead of the above graph, I need a graph which should have date with time in X-axis. what do i need to do to get time?
Another one is, I need to draw a vertical line to make two seperate parts like pre cutover, post cutover in that graph for particular date.
Eg. I need a vertical line on the date "2012-Apr-25 11:00"
How do I solve this problems? Can anyone help me to solve these problem please?

Here is my code. I m currently using 2 csv files and when i add third one nothing appears on the screen. How do i add multiple csv files here?
Graph should update itself for each csv files in every 5 seconds.
I need your help, what code has to be added to make it even more dynamic.
I tried this part in code to make it work with 3 csv, But it din work.
function updateData() {
// Get the data again
d3.csv("data-alt.csv", function(error, data) {
d3.csv("alt.csv-data", function(error, data) {
data.forEach(function(d) {
d.date = parseDate(d.date);
d.close = +d.close;
});

You should break your function that handles parsing the result into another function, then just call d3.csv multiple times passing in the correct URL for the csv and the specific handler for that csv file.
Here is a quick snippet with the changes i suggested:
// Set the dimensions of the canvas / graph
var margin = {
top: 30,
right: 20,
bottom: 30,
left: 50
},
width = 600 - margin.left - margin.right,
height = 270 - margin.top - margin.bottom;
// Parse the date / time
var parseDate = d3.time.format("%d-%b-%y").parse;
// Set the ranges
var x = d3.time.scale().range([0, width]);
var y = d3.scale.linear().range([height, 0]);
// Define the axes
var xAxis = d3.svg.axis().scale(x)
.orient("bottom").ticks(5);
var yAxis = d3.svg.axis().scale(y)
.orient("left").ticks(5);
// Define the line
var valueline = d3.svg.line()
.x(function(d) {
return x(d.date);
})
.y(function(d) {
return y(d.close);
});
// Adds the svg canvas
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",

data.forEach(function(d) {
d.date = parseDate(d.date);
d.close = +d.close;
});

return d.date;
}));

How can I make a scatterplot plotting time of day against date, which looks like this in using javascript and d3? The problem I am having is formatting the time of day data and axis. Input of the date is in the y column format below.
Sample data:
Day Time
5-Feb-16 21:35:00
5-Feb-16 19:15:00
11-Dec-15 21:42:00
21-Jul-15 11:00:00

My output:
Is there a way to parse times and be able to plot them directly using javascript and d3? Or do I need to convert them to decimal numbers like 12:30 = 12.5 to plot them?
If you're using time in the y scale, you should parse the Time column as well:
var parseDate = d3.time.format("%d-%b-%y").parse;
var parseTime = d3.time.format("%H:%M:%S").parse;
Here is your code with just 4 points (the ones of the CSV you copy/pasted in your question):
var margin = {
top: 30,
right: 20,
bottom: 30,
left: 80
},
width = 600 - margin.left - margin.right,
height = 270 - margin.top - margin.bottom;
// Parse the date / time
var parseDate = d3.time.format("%d-%b-%y").parse;
var parseTime = d3.time.format("%H:%M:%S").parse;
// Set the ranges
var x = d3.time.scale().range([0, width]);
var y = d3.time.scale().range([height, 0]);
// Define the axes
var xAxis = d3.svg.axis().scale(x)
.orient("bottom").ticks(5);
var yAxis = d3.svg.axis().scale(y)
.orient("left");
// Define the line
var valueline = d3.svg.line()
.x(function(d) {
return x(d.Day);
})
.y(function(d) {
return y(d.Time);
});
// Adds the svg canvas
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 + ")");
// Get the data
var data = d3.csv.parse(d3.select("#csv").text());
data.forEach(function(d) {
d.Day = parseDate(d.Day);
d.Time = parseTime(d.Time);
});
// Scale the range of the data
x.domain(d3.extent(data, function(d) {
return d.Day;
}));
y.domain([parseTime("00:00:01"), parseTime("23:59:59")]);
// Add the valueline path.

I'm following this example by Mike himself. The timeFormat in the example is ("%d-%b-%y"), but using my own data uses just the year. I've made all the necessary changes (I think). The y-axis shows, but the x-axis doesn't. There are also no errors showing, so I'm not sure where to go. Below is my code. Thanks!

You have another date format. Try this:
var parseDate = d3.time.format("%d-%m-%Y").parse;
And use d.date instead of d.time in your x.domain:
x.domain(d3.extent(data, function(d) { return d.time; }));
Demo: https://embed.plnkr.co/SGRyjWxjReXq8ENLd4LI/
I'm trying to run a basic d3.js line graph but I keep getting an error in the function d3_time_parse. The example I'm attempting to copy is here: http://bl.ocks.org/d3noob/b3ff6ae1c120eea654b5
Specifically, the error is d3.v3.js:2550 Uncaught TypeError: Cannot read property 'length' of undefined corresponding to
2549: function d3_time_parse(date, template, string, j) {
2550: var c, p, t, i = 0, n = template.length, m = string.length;
My code:
<!DOCTYPE html>
<meta charset="utf-8">
<style> /* set the CSS */
body { font: 12px Arial;}
path {
stroke: steelblue;
stroke-width: 2;
fill: none;

A few users have asked similar questions, and the issues were fixed after correcting the time format used in var parseDate and making sure the CSV values are separated by commas. I've checked for these issues and still no luck.
I determined there was an issue with the .csv file after I downloaded the data file from the example website I was using.
Although the .csv files look identical in excel, the code only runs when I use the file downloaded from the example site.
