D3 Legend Placement - javascript

I have a donut chart with lots of labels and need place the labels preferably in a an unorder list so they will resize based on the size of the parent element.
I am going off of this example: http://zeroviscosity.com/d3-js-step-by-step/step-3-adding-a-legend
I still don't fully understand D3 and working quick to use it. Thanks for any suggestions you have!!
Here is my code.
JS
(function(d3) {
'use strict';
var width = 760;
var height = 760;
var radius = Math.min(width, height) / 2;
var donutWidth = 275;
var legendRectSize = 18;
var legendSpacing = 4;
var color = d3.scale.category20b();
var svg = d3.select('#chart')
.append('svg')
.attr('width', width)
.attr('height', height)
.append('g')
.attr('transform', 'translate(' + (width / 2) +
',' + (height / 2) + ')');
var arc = d3.svg.arc()
.innerRadius(radius - donutWidth)
.outerRadius(radius);
var pie = d3.layout.pie()
.value(function(d) { return d.count; })
.sort(null);
var tooltip = d3.select('#chart')
.append('div')
.attr('class', 'tooltip');
tooltip.append('div')
.attr('class', 'label');
tooltip.append('div')
.attr('class', 'count');

.attr('class', 'percent');

Create a new div and give it some styles. also set the opacity to 0.
var popupDiv = d3
.select("#root")
.append("div")
.attr("class", "tooltip")
.style("opacity", 0);
Next, you need to add a mouseenter and mouseout to your desired elements
d3.append("div") // Change this to your element(s)
.on("mouseenter", function (d, i) {
popupDiv.transition().duration(200).style("opacity", 0.9);
popupDiv
.html(i.Description) // Example of display a data item description
.style("left", d.pageX + "px") // X offset can be added here
.style("top", d.pageY + "px"); // Y offset can be added here
})
.on("mouseout", function (d, i) {
popupDiv.transition().duration(200).style("opacity", 0);
})
Bear in mind the first parameter d to the mouseenter and mouseout functions is the mouse event itself which is being used to find out the x and y position of the mouse. The second parameter i is the data attached to your element if you wanted to use any of the data for specific descriptions or colours etc.
These are the base styles I used when creating a popup
div.tooltip {
position: absolute;
text-align: center;
width: auto;
height: auto;
max-width: 200px;
padding: 8px;
font: 12px sans-serif;
background: lightsteelblue;
border: 0px;
border-radius: 8px;
pointer-events: none;
z-index: 10;

Displaying selections to an SVG rectangle (JavaScript)

I saw this post last night and wanted to replicate it/make it better - because it interested me. However, I'm stuck on displaying the selections to an SVG rectangle. I thought by appending text to the function where the Lasso is called would work, however it doesn't. I've included the problematic code and would like to know where I've gone wrong for me to improve. Thanks.
If you need anymore code, holla.
var textBox = svg.append("g")
.attr("transform", "translate(5,385)");
textBox.append("rect")
.attr("height", 10)
.attr("width", 100)
.style("stroke", "black")
.style("fill", "none")
.style("stroke-width", 1);
var lasso_start = function() {
lasso.items()
.attr("r",7)
.classed("not_possible",true)
.classed("selected",false);
};
var lasso_draw = function() {
lasso.possibleItems()
.classed("not_possible",false)
.classed("possible",true);
lasso.notPossibleItems()
.classed("not_possible",true)
.classed("possible",false);
};
var lasso_end = function() {
lasso.items()
.classed("not_possible",false)
.classed("possible",false);
selected = lasso.selectedItems()
.classed("selected", true)
.attr("r", 13);
var selectedDots = selected.data().map(d=>d[0]);
};
var lasso = d3.lasso()
.closePathSelect(true)
.closePathDistance(100)
.items(circles)
.targetArea(area)
.on("start",lasso_start)
.on("draw",lasso_draw)
.on("end",function(d) {
textBox.append("text")
.attr("x", 10)
.attr("y", 20)
.text(lasso_end)
});
svg.call(lasso);

Modifying the block that I posted as an answer to this post to include the selections in a rect, here's a fork for the same:
https://bl.ocks.org/shashank2104/d58381c96971ff131c03e8832470085b/151651c9fa3e94fef46e243227924f4e4c90cf01
And a code snippet if that's convenient:

Relevant changes:
Based on the selections, I've added a function that adds texts to the textBox with an enter/exit/merge logic and assigns widths to the rect based on the maximum length of the text.
var modifyTextBox = function (selected) {
if(selected.length) {
var widths = [], textHeight = 0;
var texts = textBox.selectAll('text.selection')
.data(selected);
texts.exit().remove();
texts
.enter().append('text').attr('class', 'selection').attr('x', '3')
.merge(texts)
.attr('y', function (d, i) {
return i * 13 + 12;
}).text(function (d) { return d; });
textBox.selectAll('text.selection')
.each(function (d) {
widths.push(d3.select(this).node().getBBox().width);
textHeight = d3.select(this).node().getBBox().height;
});
var maxW = selected.length ? d3.max(widths) : 0;
textBox.style('display', null).select('rect').attr('width', maxW+10).attr('height', selected.length*textHeight);
} else {
textBox.style('display', 'none');
}
};
And calling this in the lasso_end function as: modifyTextBox(selectedDots);
And I've added some CSS for this textBox and the texts within it:
.textBox rect {
fill: steelblue;
}
text.selection {
font-size: 12px;
fill: #FFF;
letter-spacing: 0.1em;
font-weight: 300;
}
Feel free to play around with this function to position the rect (probably based on the mouse).
Hope this helps.

Applying zoom in matrix scatterplot d3.js v4

Here is a plunkr of a matrix scatterplot in d3 V4
http://plnkr.co/edit/7meh4sMhxItcQtCaAtZP?p=preview
(It may take some time to load and display)
I am looking forward to zoom the plot in order to see the cluttered points in a convenient way.
I have used d3.zoom() to rescale the axis but the circles are not being plotted accordingly.
Here is the problem description:
Initially, all the axis are set with different ranges (like top y-axis is having range from 4.5-7.5 , below that y-axis range is from 2.0-4.0 .. )
Now after zooming it, (i.e when scrolling mouse over the circles), all the axis are set in the same ranges that leads to all circles oriented diagonally.
Is there a workaround for that so that we can zoom the axis accordingly and visualize it nicely !!
Thanks. Any help would highly appreciated.

I think move'new_xScale = d3.event.transform.rescaleX(x)' after 'x.domain(attr2Domain[d])' inside each function should work. The same as y.

D3 text not centered on nodes?

I have a jsfiddle with a scatter plot, on which the corresponding text will not align with the dots.
I believe that this chunk should be displaying the names at the same coordinates as the circles:
.attr("x", function(d){return timeScale(d[1]);})
.attr("y", function(d){return rankScale(d[0]);})
This is the same code I used to place the circles.
Do I misunderstand something?

Since you are (for whatever reason) translating the circles, you should apply the same translate to the texts:
textSelection.attr("transform", "translate("+transRight+","+transDown+")")
Alternatively, don't translate the circles.

PS: in your text selection, don't do theBody.selectAll("text"), because you already have texts in that SVG. Instead of that, select something that doesn't exist, like theBody.selectAll("foo").

Hello I want to right align my legend after the pie chart. But with my codes they are getting aligned to left before pie chart. What CSS changes should I make to do this.

Please give some idea how to solve this problem. I am stuck in this code.
Thanks for help in advance.

You need to add x and y attributes to the legend.
legend.attr("x", width - 65)
.attr("y", 25)
Here is the full code and working example for you
