Problems with grouped bar chart

I am new to d3 and trying to make a grouped bar chart following this and this websites.
The following is my code for the scales
x0 = d3.scaleTime()
.domain([
d3.min(dataset, function(d) {return d.date;}),
d3.max(dataset, function(d) {return d.date;})
])
.range([0,w]);
x1 = d3.scaleOrdinal()
.domain([dataset.WorldPopulation, dataset.InternetUser]);
// .rangeRound([0, x0.bandwidth()]);
y = d3.scaleLinear()
.domain([0, d3.max(dataset, function(d) {return d.WorldPopulation})])
.range([h,0]);
In the website above they use scaleOrdinal but I used scaleTime as x0. Therefore I'm not too sure if that works.
This is my code for the append(rect) for the bar chart
var date = svg.selectAll(".date")
.data(dataset)
.enter()
.append("g")
.attr("class", "g")
.attr("transform", function(d) {return "translate(" + x0(d.date) + ",0)";});
/* Add field1 bars */
date.selectAll(".bar.field1")
.data(d => [d])
.enter()
.append("rect")
.attr("class", "bar field1")
.style("fill","blue")
.attr("x", d => x0(d.WorldPopulation))
.attr("y", d => y(d.WorldPopulation))
.attr("width", x1.bandwidth())
.attr("height", d => {
return height - margin.top - margin.bottom - y(d.WorldPopulation)
});
/* Add field2 bars */
date.selectAll(".bar.field2")
.data(d => [d])
.enter()
.append("rect")
.attr("class", "bar field2")
.style("fill","red")
.attr("x", d => x0(d.InternetUser))
.attr("y", d => y(d.InternetUser))
.attr("width", x1.bandwidth())
.attr("height", d => {
return height - margin.top - margin.bottom - y(d.InternetUser)
});
And this is my csv file. Not too sure how to upload excel so I took a screenshot.
Any help provided will be appreciated. Feel free to request for any extra snippets of my code for clarification.
edit: After tweaking the code, no errors are shown but the svg is not produced either.

Using scaleBand for both x0 and x1, the following code works:
<script src="js/d3.v4.js"></script>
<script>
var margin = { top: 20, right: 20, bottom: 30, left: 40 },
width = 960 - margin.left - margin.right,
height = 500 - margin.top - margin.bottom;
var x0 = d3.scaleBand()
.rangeRound([0, width]).padding(.1);
var x1 = d3.scaleBand();
var y = d3.scaleLinear()
.range([height, 0]);
var xAxis = d3.axisBottom()
.scale(x0)
.tickSize(0);
var yAxis = d3.axisLeft()
.scale(y);
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("InternetUserStats.csv", function (error, data) {
var dates = data.map(function (d) { return d.date; });
var ymax = d3.max(data, function (d) { return Math.max(d.WorldPopulation, d.InternetUser); });
x0.domain(dates);
x1.domain(['WorldPopulations', 'InternetUsers']).rangeRound([0, x0.bandwidth()]);
y.domain([0, ymax]);
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")
.call(xAxis);
svg.append("g")
.attr("class", "y axis")
.call(yAxis);
var date = svg.selectAll(".g")
.data(data)
.enter().append("g")
.attr("class", "g")
.attr("transform", function (d) { return "translate(" + x0(d.date) + ",0)"; });
/* Add field1 bars */
date/*.selectAll(".bar.field1")
.data(data)
.enter()*/
.append("rect")
.attr("class", "bar field1")
.style("fill", "blue")
.attr("x", function (d) { return x1('WorldPopulations'); })
.attr("y", function (d) { return y(+d.WorldPopulation); })
.attr("width", x0.bandwidth() / 2)
.attr("height", function (d) {
return height /*- margin.top - margin.bottom*/ - y(d.WorldPopulation)
});
/* Add field2 bars */
date/*.selectAll(".bar.field1")
.data(data)
.enter()*/
.append("rect")
.attr("class", "bar field2")
.style("fill", "red")
.attr("x", function (d) { return x1('InternetUsers'); })
.attr("y", function (d) { return y(d.InternetUser); })
.attr("width", x0.bandwidth() / 2)
.attr("height", function (d) {
return height /*- margin.top - margin.bottom*/ - y(d.InternetUser)
});
});
</script>
EDIT: the following code adds a legend that is based on your comment and your second link:
//This code goes after field2 bars are added.
/* Legend */
var legend = svg.selectAll(".legend")
.data(['WorldPopulations', 'InternetUsers']) //Bind an array of the legend entries
.enter().append("g")
.attr("class", "legend")
.attr("font-family", "sans-serif")
.attr("font-size", 13)
.style("text-anchor", "end")
.attr("transform", function (d, i) { return "translate(0," + i * 20 + ")"; });
legend.append("rect")
.attr("x", width - 18)
.attr("width", 18)
.attr("height", 18)
.style("fill", function (d) {
// Return "blue" for "WorldPopulations" and "red" for "InternetUsers":
return ((d === "WorldPopulations") ? "blue" : "red");
});
legend.append("text")
.attr("x", width - 24)
.attr("y", 9)
.attr("dy", ".35em")
//.style("text-anchor", "end") //Already applied to .legend
.text(function (d) { return d; });

Grouping bar and line charts

I am trying to group bar chart and line chart in d3 js and I followed one Link for that purpose,
Here is what my Ajax is returning in response:
[
{
"date_created": "2017-12-27",
"jobs_fail": 19,
"jobs_resub": 31,
"jobs_success": 50
},
{
"date_created": "2017-12-29",
"jobs_fail": 18,
"jobs_resub": 25,
"jobs_success": 44
},
{
"date_created": "2017-12-28",
"jobs_fail": 8,
"jobs_resub": 24,
"jobs_success": 44
},
{
"date_created": "2018-01-02",
"jobs_fail": 2,
"jobs_resub": 0,
"jobs_success": 0
}
]
And what I am trying to show is displaying the jobs_fail and jobs_resub as a bar and jobs_sucess as line chart in same graphs with respect to date_created,
Here is my code for that purpose.

UPDATE
What problem I am facing is I am able to render bar but not the line chart on bars.
I am trying to debug but not able to do so.
Please let me know what might I am doing wrong here.

You have some minor problems and a big problem.
The minor problems are:
Your y scale should take into account the maximum value in your dataset:
y.domain([0, d3.max(obj, function(d) {
return d.jobs_success
})]);
Your line generator should use x0. Besides that, you'll have to move the line by half rangeBand:
.x(function(d) {
return x0(d.date_created) + x0.rangeBand() / 2;
})
By default, a <path> has a black fill. Change it:
.style("fill", "none")
Those, however, are minor problems. The biggest problem lies here, in the data() method:
svg.append("path")
.data(obj)
.attr("class", "line")
.attr("d", line);
Let's see in detail what's happening here. You're passing the obj array to the data(). However, if you do this, each element of that array will be passed, individually, to the line generator.
So, supposing that this is your array...
["foo", "bar", "baz"]
...what you're passing to the line generator is just:
"foo".
You have some different solutions here. First, you can pass the array to the line generator directly, as you did in your edit. Second, you can wrap the array in an outer array:
svg.append("path")
.data([obj])
.attr("class", "line")
.attr("d", line);
That way, the whole obj array will be passed to the line generator.
Or, third, you can use datum:
svg.append("path")
.datum(obj)
.attr("class", "line")
.attr("d", line);
Here is your code with those changes and using datum to draw the path:
var obj = [{
"date_created": "2017-12-27",
"jobs_fail": 19,
"jobs_resub": 31,
"jobs_success": 50
}, {
"date_created": "2017-12-29",
"jobs_fail": 18,
"jobs_resub": 25,
"jobs_success": 44

Ok a couple of things. Your line's x function should be relying on x0 not x1:
var line = d3.svg.line()
.x(function(d) { return x0(d.date_created); })
.y(function(d) { return y(d.jobs_success); });
And your path needs to be called like this:
svg.append("path")
.attr("class", "line")
.attr("d", line(obj));
That should get you most of the way there - you might want to tweak the maximum y-value, and shift the x co-ordinate of the line by x0.rangeBand()/2 as well to make it line up properly with the centre of the bars.

D3 V4: Zoom & drag multi-series line chart

I am drawing charts with d3 4.2.2 in my Angular2 project. I created a multi series line chart and added zoom and drag properties. Now the chart is zooming on mouse scroll event but it zoom only X-axis and Y-axis. And it can be dragged only X-axis & Y-axis but chart cannot be dragged. When I do zooming or dragging those events are applying only to the two axis es but not for the chart. Following is what I am doing with my code.
// set the dimensions and margins of the graph
var margin = {
top: 20,
right: 80,
bottom: 30,

},
width = 960 - margin.left - margin.right,

var y = d3.scaleLinear().range([height, 0]);
var z = d3.scaleOrdinal(d3.schemeCategory10);
// define the line
var line = d3.line()
.x( (d) => {

how to left align ticks in d3 bar chart

i created a stacked bar graph.
on the y axis side i have ticks with varying lengths.
what i am trying to accomplish is to align the text in the tick to the left.
this is my example:http://jsfiddle.net/2khbceut/2/

as can be seen the current positioning of the tick text is to the right.
i tried the following idea:
svg.append("g")
.attr("class", "y axis")
.call(yAxis)
.selectAll("text")
.style("text-anchor", "start");
but it did not position the ticks in the desired alignment.
any ideas?

You can make the Y axis right-oriented, which will have the effect of positioning all the labels to the right of the axis, left-aligning them:
var yAxis = d3.svg.axis()
.scale(y)
.orient("right")// <- 1st step
At that point the labels would disappear, because they'll get covered up by the bars of the graph.
But then you can shift all those left-aligned labels some constant distance in the negative X direction, such that they're back on the left side of the Y axis, but still left-aligned the way you wanted. tickPadding() is a way to shift them:
var yAxis = d3.svg.axis()
.scale(y)
.orient("right")
.tickPadding(-180)
Here's your example, modified with the above: http://jsfiddle.net/2khbceut/3/
Maybe hardcoding the -180 is ok for you. If you need that amount to be dynamic, you can compute it using getBBox() on each text element of the axis and taking the maximum width to be the negative offset.

You can set the text-anchor to "start" and adjust the x position with translate, I added the code below in the chart model "boxPlotChart.js"
g.select('.nv-y.nv-axis').selectAll('.tick').selectAll('text')
.style('text-anchor','start')
.attr('transform', function(d,i,j) { return 'translate(-14,0)' });
g.select('.nv-y.nv-axis').selectAll('.nv-axisMaxMin').selectAll('text')
.style('text-anchor','start')
.attr('transform', function(d,i,j) { return 'translate(-16,0)' });

d3 stacked bar chart values not showing up on chart

So I have created a D3 Stacked Bar Chart, but I can't seem to figure out how to make the values of the bars show up on the chart. I can display Text "Sample" to each bar, but I can't figure out how to retrieve the data. I tried using this... .text(function(d) {return d.total; }) but with no luck.

You have to change this line
.data(function(d) { return d.ages; })
to actually give data() your data. If you have an array with all the ages named ages, then it would be:
.data(ages)
The d argument in function(d) references nothing since data() is actually the method where you input your data.
