d3.js x axis specific number of string ticks

I am trying to generate a area chart with a x axis set to fixed number of ticks (10) where each tick is a string value from the data set used for the chart. I can't figure out what I am doing wrong here:

See the bold part, the count is only a hint value.
A stateless method that returns approximately count representative values from the scale's input domain. If count is not specified, it defaults to 10. The returned tick values are uniformly spaced, have human-readable values (such as multiples of powers of 10), and are guaranteed to be within the extent of the input domain. Ticks are often used to display reference lines, or tick marks, in conjunction with the visualized data. The specified count is only a hint; the scale may return more or fewer values depending on the input domain.
If you want to display the number of ticks exactly as you wanted, you can use the API tickValues.

Is there a way to parse times and be able to plot them directly using javascript and d3?

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) {

why does it fail saying that d3 is not defined when served as string in webbrowser

I am trying to launch a WPF webbrowser from a string. I have a java script file referenced in the head section that points to a file on my drive. It looks good to me but still fails. Any ideas?

Previously the reference to d3.min.js was placed after the <script> tag and before renderLineChart() function call and it worked just fine.

So it appears that the answer is within the string formatting where a space in a file path name was replaced with %20 and rendered such path unreadable. I used Uri.UnescapeDataString() to clean that up and it works great. Thanks!

Could be the problem is caused in the first line of code, where var is shown as Var. See if that helps
Var margin = {
top: 30,
right: 20,
bottom: 30,
left: 50
},

You're missing a space in your CSS:
.grid.tick {
stroke: lightgrey;
opacity: 0.7;
}
should be
.grid .tick {
stroke: lightgrey;
opacity: 0.7;
}
or if you want to be more precise
g.grid g.tick line {
stroke: lightgrey;
opacity: 0.7;
}
The axis function creates <g> elements with a class "tick". You're drawing these inside a <g> element with class "grid". However, without the space the CSS selector .grid.tick only applies when both classes are on the same element.

Filtering out weekend days from time series line chart in D3.js

date close
2013-09-17 178
2013-09-16 185
2013-09-15 20
2013-09-14 10
2013-09-13 190

2013-09-11 150
2013-09-10 189
2013-09-09 183
2013-09-08 11
2013-09-07 20

var line = d3.svg.line()

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) {
data.forEach(function(d) {
d.date = parseDate(d.date);
d.close = +d.close;
});
x.domain(d3.extent(data, function(d) { return d.date; }));
y.domain(d3.extent(data, function(d) { return d.close; }));
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")
.call(xAxis);
svg.append("g")
.attr("class", "y axis")
.call(yAxis)

This example from Crossfilter.js seems to achieve weekend filtering—but only for a small portion of the dataset. Ideally, I would be able to filter by day using checkboxes (e.g. weekdays or Mondays only) across the entire dataset.

d3.js line graph axis not displaying data correctly

I can't figure out why the data won't display correctly. I think it has something to do with the scale of the axis but I can't find any solutions. There is a line being drawn but it's to small to see. The example I was using had a time scale of several years where as I am only doing one week.
Below is the code.
<!DOCTYPE html>
<meta charset="utf-8">

body {
font: 10px sans-serif;
}
.axis path,
.axis line {
fill: none;

var parseDate = d3.time.format("%d-%b-%y").parse;
var x = d3.time.scale()
.range([0, width]);
var y = d3.scale.linear()
.range([height, 0]);
var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom");
var yAxis = d3.svg.axis()
.scale(y)
.orient("left");
var line = d3.svg.line()
.x(function(d) { return x(d.date); })
.y(function(d) { return y(d.close); });
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 + ")");
var data = [{"close":71,"date":"9-Apr-13"},{"close":14,"date":"9-Apr-13"},{"close":10,"date":"9-Apr-13"},{"close":109,"date":"9-Apr-13"},{"close":62,"date":"9-Apr-13"},{"close":61,"date":"9-Apr-13"},{"close":62,"date":"9-Apr-13"},{"close":32,"date":"9-Apr-13"},{"close":19,"date":"9-Apr-13"}];

Based on the data you've provided, there is only one instance of time: Apr 9, 2013. Since there is no difference between min and max, the x axis won't display.
If you change one date to Apr 11, It looks right.
Bear in mind that your css says
.x.axis path {
display: none;
}
so the actual line for the x axis won't display no matter what
