I had some simple problems in D3.JS

https://i.stack.imgur.com/90isf.png
When visualizing the data, I got some troubles of X axis of line chart.
As picture shows, line of X axis disappeared, in fact, it only shows the scale of X axis. I wonder why this condition happens. Was it due to the illegal coding or because of the size of SVG was not big enough to contain the whole picture?
var margin = { top: 30, right: 120, bottom: 30, left: 50 },

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; });

D3.js path goes in different directions in V3 vs V4

I'm attempting to make the same multi-line graph in D3 V3 and V4, but they behave differently for reasons I don't understand. What can I change in my V4 code that will make the paths connect in the correct order (according to the x axis instead of the y axis)?
Here's what V3 gives, taken from the jsfiddle I made for it:
...But here's V4:
Jsfiddle doesn't support V4 yet, so here's my code:
var margin = {top: 20, right: 40, bottom: 100, left: 100},
width = 500 - margin.left - margin.right,
height = 400 - margin.top - margin.bottom;
var x = d3.scaleLinear().range([0, width]);
var y = d3.scaleLinear().range([height, 0]);
var xAxis = d3.axisBottom(x);
var yAxis = d3.axisLeft(y);
var line = d3.line()
.x(function(d) { return x(d.depth); })
.y(function(d) { return y(d.carat); });
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("diamonds.csv", function(error, data) {
data.forEach(function(d) {
d.carat = +d.carat;
d.depth = +d.depth;
//d.cut = +d.cut;
})
data.sort(function(a,b) { return a.x - b.x; });
x.domain(d3.extent(data, function(d) { return d.depth; })).nice();
y.domain(d3.extent(data, function(d) { return d.carat; })).nice();
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")
.call(xAxis)
.selectAll("text")
.attr("y", 6)
.attr("x", 5)
.attr("dy", ".35em")
.attr("transform", "rotate(45)")
.style("text-anchor", "start")
var dataNest = d3.nest()
.key(function(d) {return d.cut;})
.entries(data);
svg.append("g")
.attr("class", "y axis")
.call(yAxis)
.append("text")
.attr("class", "label")
.attr("transform", "rotate(-90)")
.attr("y", 6)
.attr("dy", ".71em")
.style("text-anchor", "end")
.text("Price");
var color = d3.scaleOrdinal(d3.schemeCategory10);
dataNest.forEach(function(d) {
svg.append("path")
.attr("class", "line")
.style("stroke", function() { // Add the colours dynamically
return d.color = color(d.key); })
.attr("d", line(d.values));
});
});

If you look at your code using D3 v3.x, you did this after loading the data:
data.forEach(function(d) {
d.x = +d.depth;
d.carat = +d.carat;
})
And using that property x for sorting:
data.sort(function(a,b) { return a.x - b.x; });
However, in your v4.x version, you did:
data.forEach(function(d) {
d.depth = +d.depth;
d.carat = +d.carat;
})
And used an nonexistent x for sorting (the problem with sorting alone was making the lines different from v3.x).
Solution: use depth for sorting:
data.sort(function(a,b) { return a.depth - b.depth; });
Here is your code using v4.x version:
var margin = {
top: 20,
right: 40,
bottom: 100,
left: 100
},
width = 500 - margin.left - margin.right,
height = 400 - margin.top - margin.bottom;
var x = d3.scaleLinear().range([0, width]);
var y = d3.scaleLinear().range([height, 0]);
var xAxis = d3.axisBottom(x);
var yAxis = d3.axisLeft(y);
var line = d3.line()
.x(function(d) {
return x(d.depth);
})
.y(function(d) {
return y(d.carat);
});
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 = d3.csvParse(d3.select("pre#data").text());
data.forEach(function(d) {
d.carat = +d.carat;
d.depth = +d.depth;
//d.cut = +d.cut;
})
data.sort(function(a, b) {
return a.depth - b.depth;
});
x.domain(d3.extent(data, function(d) {
return d.depth;
})).nice();
y.domain(d3.extent(data, function(d) {
return d.carat;
})).nice();
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")

.attr("y", 6)
.attr("x", 5)

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,
left: 50
},
width = 960 - margin.left - margin.right,
height = 500 - margin.top - margin.bottom;
var zoom = d3.zoom()
.scaleExtent([1, 5])
.translateExtent([[0, -100], [width + 90, height + 100]])
.on("zoom", zoomed);
var svg = d3.select(this.htmlElement).append("svg")
.attr("class", "line-graph")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom)
.append("g")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")")
.attr("pointer-events", "all")
.call(zoom);
var view = svg.append("rect")
.attr("class", "view")
.attr("x", 0.5)
.attr("y", 0.5)
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom)
.style("fill", "#EEEEEE")
.style("stroke", "#000")
.style("stroke-width", "0px");
// parse the date / time
var parseDate = d3.timeParse("%Y-%m-%d");
// set the ranges
var x = d3.scaleTime().range([0, width]);
var y = d3.scaleLinear().range([height, 0]);
var z = d3.scaleOrdinal(d3.schemeCategory10);
// define the line
var line = d3.line()
.x( (d) => {
return x(d.date);
})
.y( (d) => {
return y(d.lookbookcount);
});
z.domain(d3.keys(data[0]).filter(function (key) {
return key !== "date";
}));
// format the data
data.forEach( (d)=> {
d.date = parseDate(d.date);
});
var lookBookData = z.domain().map(function (name) {
return {
name: name,
values: data.map( (d) => {
return {date: d.date, lookbookcount: d[name], name: name};
})
};
});
x.domain(d3.extent(data, (d) => {
return d.date;
}));
y.domain([
d3.min([0]),

})
.attr("cy", function (d) {

})
.style("fill", function (d) { // Add the colours dynamically
return z(d.name);
});
function zoomed() {
view.attr("transform", d3.event.transform);
gX.call(xAxis.scale(d3.event.transform.rescaleX(x)));
}
function resetted() {
svg.transition()
.duration(750)
.call(zoom.transform, d3.zoomIdentity);
}
Any suggestions would be highly appreciated.
Thank you

D3 bar chart with autosize

Good afternoon.
I need to automatic update the size of the chart.
My code is above.
My data is something like this, when the data is small i do not have problem but when it is big the values in xAxis and the bars are overlapping.
var data = [
{key:1, value:5},
{key:2, value:10},
{key:3, value:15},
{key:4, value:26},
{key:5, value:33}
];
var margin = {
top: 30,
right: 10,
bottom: 30,
left: 30
},
width = 900 - margin.left - margin.right,
height = 300 - margin.top - margin.bottom;
var x = d3.scale.ordinal()
.domain(data.map(function(d) {
return d.key;
}))
.rangeRoundBands([margin.left, width], 0.05);
var y = d3.scale.linear()
.domain([0, d3.max(data, function(d) {
return d.value;
})])
.range([height, 0]);
var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom");
var yAxis = d3.svg.axis()
.scale(y)
.orient("left");
var key = function(d) {
return d.key;
};
var svg = d3.select("#chart").append("svg")
.attr("width", width + margin.left + margin.right + 10)
.attr("height", height + margin.top + margin.bottom)
.append("g")
.text("Your tooltip info")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")");
svg.append("text")
.attr("x", (width / 2))
.attr("y", 0 - (margin.top / 2))
.attr("text-anchor", "middle")
.style("font-size", "16px")
.style("text-decoration", "underline")
.text("Log(number sts) vs Nodes - Gen" + " " + startGen + " "+"to" + " "+ endGen)
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(-30," + height + ")")
.call(xAxis)
.append("text")
.attr("x", width)
.attr("dy", 30)
.attr("text-anchor", "end")
.text("Number of nodes");
svg.append("g")
.attr("class", "y axis")
.call(yAxis)
.append("text")
.attr("transform", "rotate(-90)")
.attr("y", -30)
.attr("dy", ".71em")
.style("text-anchor", "end")
.text("Log(Number Sts)");
var bars = svg.selectAll("rect")
.data(data, key)
.enter().append("rect")
.attr("x", function(d) {
return x(d.key) + x.rangeBand() / 2 - 40;
})
.attr("y", function(d) {
return y(d.value);
})
.attr("width", 20)
.attr("height", function(d) {
return height - y(d.value);
})
.style("fill", "blue");

If you want to size the chart according to how much data you have then you can simply replace your "width" variable with a calculation: something like:
width = Math.min(900, 20 * data.length);
But perhaps what you mean is to size the bars based on how much room there is? You are already using x.rangeBand that gives you the available range width - try using that for the bar width
...
.attr("width", x.rangeBand())
If you want to get fancy you can have finer control over the bar width and gap. Something like:
var barWidth = Math.max(1, 0.9 * x.rangeBand());
var halfGap = Math.max(0, x.rangeBand() - barWidth) / 2;
var bars = svg.selectAll("rect")
.data(data, key)
.enter().append("rect")
.attr("x", function(d) {
return x(d.key) + halfGap - 30 ;
})
.attr("width", barWidth)
...
