I have an existing bar chart which works fine.
But I want to make it horizontal by flipping the axis.
Full code:
$(document).ready(function() {
render_chart();
});
function render_chart() {
var stack = d3.stack;

I tried to do it but I mess it up everytime. When I try to flip the axis by changing the portion below which is just reversing the x and y, it does not appear correctly:
var xAxis = d3.axisBottom(xScale)
.tickSize(7)
.tickPadding(6);
var yAxis = d3.axisLeft(yScale).ticks(24);
I can't figure this out.
Why:
So that I can fit more stuff per group of bars when they are horizontal as they are going to be long and have more space inside.
Here is a reversed (horizontal) version of your chart:

This requires a bit more than just switching x and y axes. You'll also have to modify the w/y/width/height attributes of rectangles, as well as the the position of axes.
I've marked the modified lines with //.
Just for the fun (and if like me, starting from a vertical graph, you're lost doing all these inversions of axes/scales), here is another way of doing using a rotation by 90° of the whole graph!:

I have a D3.js histogram graph that has an issue where my last x-axis bin is significantly smaller than than the rest of the bins which are equal width. At first I thought this was a axis issue, but the axis is set with the typical width and height range and domains, making me believe it has to do with my bar code, but I'm not sure what would create just one wrong width for a bing, while the other bins are equal width. Provided below is my code. Any help would be appreciated!

It is because the domain of x is [0, 9.34], so it ended up with 9.34 instead of 10 (to keep the same width)
Solution:
add .nice() to x to "Extends the domain so that it starts and ends on nice round values. " (See Here);
remove the last element of the new bin data otherwise there will be a zero from 10 to 11

I'm new to D3JS and struggling with stacked bar below is my dummy code. I tried adding 10 to data to make it visible and then subtract 10 from label to make the label look correct but this cause problem with yAxis where value of bar is crossing the ticker with less then bar value, for example label was showing 95 but bar crossed 100 ticker coz bar size is 95 + 10 = 105. Help me with this.[In image you can find out small bars label are not visible.

the labels are being hidden due the order in which the g elements are creating in the DOM, in that elements created later will overlap elements created earlier. This means that the INSOLVENCIES group labels will be hidden by the orange rects for the SPV/ASSETBACKED.
A solution would be to create new g element for your labels, so they always appear on top of your rects. See the snippet below.
Now, where you have small values, there will always be a challenge about where to position the labels. The snippet places them in the middle of the bar, but you may need to play around with that

hey guys i am currently trying to change the visibility of 4 lines depending on whether the slider position is at the same "year-tick" as i have in my data.
for example: i would want line 3 which has the value "1994" stored to only be visible as long as the slider is on position "1994"
i havent workder with sliders yet, which is why i am having this much trouble getting this to work.
here is a fiddle of my code: https://fiddle.jshell.net/42jdw2Lt/3/

I added the prop year to all your elements in the data selecting all the line paths in a variable called paths so that I can change the opacity when you move your slider like this
var paths = group.selectAll(".line")
.data(series)
.enter().append("path")
.attr("class", "line")
// .attr("visibility", "hidden")
.attr("stroke-width", function(d) {
return strwi(d);
})
.attr("stroke", "black")
.attr("fill", "none")
.attr("d", line);
and then in your hue function, I added this code to change the opacity based on your slider
paths.attr('opacity', function(d) {
if (((Math.round(h * 2) / 2).toFixed(1)) > d[2]['year']) {
return 0;
} else {
return 1;
}
})

Let me know if this is what you wanted or there's something else.
I am using d3.js and would like the force layout to be NOT random every time I load up the page.
I have already read over a few questions and I set the node position but the layout still is random.
Just set static x and y positions in your node objects.
var graph = {
"nodes": [{
"name": "1",
"rating": 90,
"id": 2951,
x: 5, //Any random value
y: 10 //Any random value
}, {
"name": "2",
"rating": 80,
"id": 654654,
x: 15,
y: 20
------------------
-------------------
}],
"links": [{
"source": 5,
"target": 2,
"value": 6,
"label": "publishedOn"
}, {
"source": 1,
"target": 5,
"value": 6,
"label": "publishedOn"
},

How can I change the nodes to be rectangles instead of circles in the following d3 forced directed graph?
You have to append a rect SVG element instead of a circle.
So, in the script, where it shows this:
var node = svg.selectAll(".node")
.data(graph.nodes)
.enter().append("circle")
.attr("class", "node")
.attr("r", 5)
.style("fill", function(d) { return color(d.group); })
.call(force.drag);
You should change it to maybe this:
var node = svg.selectAll(".node")
.data(graph.nodes)
.enter().append("rect")
.attr("class", "node")
.attr("width", 40)
.attr("height", 20)
.style("fill", function(d) { return color(d.group); })
.call(force.drag);
And, where it shows:
node.attr("cx", function(d) { return d.x; })
.attr("cy", function(d) { return d.y; });
Change it to:
node.attr("x", function(d) { return d.x; })
.attr("y", function(d) { return d.y; });
Change circle to rect. Remove r attribute. Add width and height attibutes. Change cx and cy in fdg to x and y:
var width = 960, height = 500;
var rectWidth = 20, rectHeight = 10;
var color = d3.scale.category20();
var force = d3.layout.force()
.charge(-120)
.linkDistance(30)
.size([width, height]);
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height);
d3.json("https://raw.githubusercontent.com/d3/d3-plugins/master/graph/data/miserables.json", function(error, graph) {
force
.nodes(graph.nodes)
.links(graph.links)
.start();
var link = svg.selectAll(".link")
.data(graph.links)
.enter().append("line")
.attr("class", "link")
.style("stroke-width", function(d) { return Math.sqrt(d.value); });
var node = svg.selectAll(".node")
.data(graph.nodes)
.enter().append("rect")
.attr("class", "node")
.attr("width", rectWidth)
.attr("height", rectHeight)
.style("fill", function(d) { return color(d.group); })
.call(force.drag);
node.append("title")
.text(function(d) { return d.name; });
force.on("tick", function() {
link
.attr("x1", function(d) { return d.source.x; })
.attr("y1", function(d) { return d.source.y; })
.attr("x2", function(d) { return d.target.x; })
.attr("y2", function(d) { return d.target.y; });
node
.attr("x", function(d) { return d.x - rectWidth / 2; })
.attr("y", function(d) { return d.y - rectHeight / 2; });
});
});
.node {
stroke: #fff;

}
.link {
stroke: #999;
stroke-opacity: .6;
}
<script src="http://d3js.org/d3.v3.min.js"></script>
Here is a simple example of using Rectangles with a json file :

stroke: #000;
stroke-width: 1.5px;
}
.node {
