D3: How to set text inside a circle

I'm newbie with D3.js and I'm trying to put a text inside a circle but I am only able to do it with one of them and not with all the circles.
You can find all the code in this snipet
And the function where I create the circles and I try to put the text inside of is "setPointsToCanvas"
setPointsToCanvas(canvas, data, scales, x_label, y_label, lang) {
canvas
.selectAll("circle")
.data(data)
.enter()
.append("circle")
.attr("class", "dot")
.attr("r", 20) //Radius size, could map to another dimension
.attr("cx", function(d) {
return scales.xScale(parseFloat(d.value_x));
}) //x position
.attr("cy", function(d) {
return scales.yScale(parseFloat(d.value_y));
}) //y position
.style("fill", "#FFC107")
.on("mouseover", tipMouseOver)
.on("mouseout", tipMouseOut);
//Ad label for each circle
canvas
.data(data)
//.enter()
.append("text")
.attr("x", function(d) {
return scales.xScale(parseFloat(d.value_x));
})
.attr("y", function(d) {
return scales.yScale(parseFloat(d.value_y) - 0.9);
})
.text(function(d) {
return d.name.substring(0, 3);
})
.style("text-anchor", "middle")
.style("font-weight", "bold")
.style("font-size", "10pt")
.style("fill", "#344761");
let tooltip = d3
//.select("#" + this.props.idContainer)
.select("body")
.append("div")
.attr("class", "tooltip-player")
.style("opacity", 0);
/**
* We define this function inside of setPointsToCanvas to get access to canvas, data, scales and tooltip
* #param {*} d
* #param {*} iter
*/
function tipMouseOver(d, iter) {
let players = data.filter(p => {
if (p.value_x === d.value_x && p.value_y === d.value_y) {
return p;
}
});
let html = "";
for (let i = 0; i < players.length; i++) {
let text_x =
lang === "es"
? String(parseFloat(players[i].value_x).toFixed(2)).replace(
".",
","
)
: parseFloat(players[i].value_x).toFixed(2);
let text_y =
lang === "es"
? String(parseFloat(players[i].value_y).toFixed(2)).replace(
".",
","
)
: parseFloat(players[i].value_y).toFixed(2);
if (i > 0) html += "<hr>";
html +=
players[i].name +
"<br><b>" +
x_label +
": </b>" +
text_x +
"%<br/>" +
"<b>" +
y_label +
": </b>" +
text_y +
"%";
}
tooltip
.html(html)
.style("left", d3.event.pageX + 15 + "px")
.style("top", d3.event.pageY - 28 + "px")
.transition()
.duration(200) // ms
.style("opacity", 0.9); // started as 0!
// Use D3 to select element, change color and size
d3.select(this)
//.attr("r", 10)
.style("cursor", "pointer");
}
/**
* We create this function inside of setPointsToCanvas to get access to tooltip
*/
function tipMouseOut() {
tooltip
.transition()
.duration(500) // ms
.style("opacity", 0); // don't care about position!
//d3.select(this).attr("r", 5);
}
}
And here you can see how I'm only able to get one text inside of one circle and not the text inside all of them.
What am I doing wrong?

Following the advice of #Pablo EM and thanks to #Andrew Reid for your appreciated help I publish the solution to my problem.
How #Andrew Reid said if I have problems with selectAll("text") I have to change it for another text grouper. How I had it, I changed by selectAll("textCircle") and everything works fine to me.
This is the code which writes the text inside each circle. This piede of code you can find it inside of "setPointsToCanvas" method.
//Ad label for each circle
canvas
.selectAll("textCircle")
.data(data)
.enter()
.append("text")
.attr("x", function(d) {
return scales.xScale(parseFloat(d.value_x));
})
.attr("y", function(d) {
return scales.yScale(parseFloat(d.value_y) - 0.9);
})
.text(function(d) {
return d.name.substring(0, 3);
})
.style("text-anchor", "middle")
.style("font-weight", "bold")
.style("font-size", "10pt")
.style("fill", "#344761");
Now, here you've got an image of the final result:
If you access to the code through CodeSandBox posted before you can access to all the code and check how it works perfectly.

D3 Map + Graph Coordinated Visualization: selecting wrong countries / map changing attributes

Here is my issue: I have a map SVG and a bar Graph SVG. I want to create a coordinated selection. For instance, the user highlights a bar in the graph and the country on the map corresponding to that data is also highlighted and Vice Versa.
Right now I can highlight any country on the map and the proper corresponding bar will also highlight. However, the same does not work for the bars. When I highlight a bar, a random country is highlighted and after that the country names, as displayed in a tooltip, are all jumbled and wrong.
Here is the map -> bar graph highlight:
...
map.selectAll("countries")
.data(b.features)
.enter()
.append("path")
.attr("d", path)
//.style("stroke", "black")
.on("mouseover", function(d) {
activeDistrict = d.properties.ADMIN,
chart.selectAll("rect")
.each(function(d) {
if(d){
if (d.Country == activeDistrict){
console.log("confirmed" + d.Country)
d3.select(this).style("stroke", "blue").style("stroke-width", "3");
}
}
})
...
Here is the bar graph -> map highlight. This is the function I cannot get to behave properly.
var bars = chart.selectAll(".bars")
.data(data)
.enter()
.append("rect")
.on("mouseover", function(d) {
activeDistrict = d.Country,
//console.log(activeDistrict),
map.selectAll("path")
.data(b.features)
.each(function(d) {
if (d){
//console.log("activeDistrict = " + activeDistrict)
if (d.properties.ADMIN == activeDistrict){
d3.select(this).style("stroke", "blue").style("stroke-width", "3");
console.log(d.properties.ADMIN + "=" + activeDistrict)
}
}
});
And here is my entire JS:
<script>
window.onload = setMap();

When drawing countries initially you use:
map.selectAll("countries")
.data(b.features)
.enter()
.append("path")
As there are no elements with the tag countries on your page, the initial selection is empty, and .enter().append("path") creates a path for each item in your data array.
But when you do a mouseover on the bars you re-assign the data with a selectAll().data() sequence, but you do it a bit differently:
map.selectAll("path")
.data(b.features)
...
There are paths in your map that aren't countries: the graticule and the outline. Now we've selected all the paths and assigned new data to them. Since the first two items in the selection are the graticule and the outline they now have the data of the first two items in the data array. All the countries will have bound data of a country that is two away from them in the data array. This is why the wrong data will be highlighted when mouseovering the bars and afterwards why the country tooltips are wrong.
It is not clear why you update the data (I don't see it changing), you could append the countries as so:
var countries = map.selectAll("countries")
.data(b.features)
.enter()
.append("path")
... continue as before
or
map.selectAll("countries")
.data(b.features)
.enter()
.append("path")
.attr("class","country")
... continue as before
And then in the mouseover function of the bars use:
countries.each(....
or
map.selectAll(".country").each(...
Either way still lets you update the data with .data() if needed.
I'll note that the each method isn't necessary, but may be preferable in some situations, by the looks of it you could use:
var bars = chart.selectAll(".bars")
.data(data)
.enter()
.append("rect")
.on("mouseover", function(d) {
activeDistrict = d.Country,
map.selectAll(".country")
.data(b.features)
.style("stroke", function(d) {
if (d.properties.ADMIN == activeDistrict) return "blue"; else return color(d.properties[currentFood])
})
.style("stroke-width", function(d) {
if (d.properties.ADMIN == activeDistrict) return "3" else return 0;
});
})
...

You might try the following to be a bit more consistent in what you create and what you select.
The map:
select by class because you have more path in the svg
add a class to the bar to highlight instead of setting a style
map.selectAll(".countries")
.data(b.features)
.enter()
.append("path")
.attr("class", "countries")
.attr("d", path)
//.style("stroke", "black")
.on("mouseover", function(d) {
activeDistrict = d.properties.ADMIN,
chart.selectAll(".bars")
.classed("highlight", function(d) {
return d && d.Country === activeDistrict;
});
tooltip.transition() //(this.parentNode.appendChild(this))
.duration(200)
.style("opacity", .9)
.style("stroke-opacity", 1.0);
tooltip.html(d.properties.ADMIN + "<br/>" + d.properties[currentFood] + "(kg/CO2/Person/Year)")
.style("left", (d3.event.pageX) + "px")
.style("top", (d3.event.pageY - 28) + "px");
})
.on("mouseout", function(d) {
activeDistrict = d.properties.ADMIN,
chart.selectAll(".bars")
.classed("highlight", false);
tooltip.transition()
.duration(500)
.style("opacity", 0)
.style("stroke-opacity", 0);
})
.style("fill", function(d) { return color(d.properties[currentFood]) });
};
Drawing of the bars
fix the class, add a space between the bars and country
do not bind new data to the map paths on mouse over and mouse out
select map paths by class not by type
add a class to the map path to highlight instead of setting a style
var bars = chart.selectAll(".bars")
.data(data)
.enter()
.append("rect")
.on("mouseover", function(d) {
activeDistrict = d.Country;
//console.log(activeDistrict),
map.selectAll(".countries")
.classed("highlight", function(d) {
return d && d.properties.ADMIN === activeDistrict;
});
tooltip.transition() //(this.parentNode.appendChild(this))
.duration(200)
.style("opacity", .9)
.style("stroke-opacity", 1.0);
tooltip.html(d.Country + "<br/>" + d[currentFood] + "(kg/CO2/Person/Year)")
.style("left", (d3.event.pageX) + "px")
.style("top", (d3.event.pageY - 28) + "px");
})
.on("mouseout", function(d) {
map.selectAll(".countries")
.classed("highlight", false);
tooltip.transition()
.duration(500)
.style("opacity", 0)
.style("stroke-opacity", 0);
})
.sort(function(a, b){
return a[currentFood]-b[currentFood]
})
.transition() //add animation
.delay(function(d, i){
return i * 5
})
.duration(1)
.attr("class", function(d){
return "bars " + d.Country;
})
.attr("width", chartWidth / data.length - 1)
.attr("x", function(d, i){
return i * (chartWidth / data.length);
})
.attr("height", function(d){
return yScale(parseFloat(d[currentFood]));
})
.attr("y", function(d){
return chartHeight - yScale(parseFloat(d[currentFood]));
})
.style("fill", function(d){ return color(d[currentFood]); });

If you change the selection of the radio button and then click on a section of the pie chart that section does not complete its transition as I believe it decides it needs to move on to its "on" event.
How do I ensure that the transition completes? (and the pie chart does not do a pac-man impersonation)

Clear your listeners when the tranistion starts.
Attach it when the transition is ended
Like this:
path2
.data(partition.value(value).nodes)
.transition()
.duration(1500)
.attrTween("d", arcTween)
.each("start", function(){
d3.select(this)
.on("mouseover", null) //CLEARING the listeners
.on("mouseout", null) //CLEARING the listeners
.on("click", null) //CLEARING the listeners
})
.each("end", function(){
d3.select(this)
.on("mouseover", mouseover) //attaching the listeners
.on("mouseout", mouseout) //attaching the listeners
.on("click", up) ////attaching the listeners
});

d3.js an Inverse bubble chart

I am interested in creating something like this. Usually we see people drawing a bubble - I am keen to draw the space to represent the bubble. I would perhaps place this mask/chart in a shared component -- that is conjoined only by a background image -- so maybe embed this in a bootstrap part like col-md-8.
I've added the the subtraction mask -- and some label/pointer stuff - but its not rendering.
http://jsfiddle.net/NYEaX/1525/
var data = [{
"label": "My Property Value over 3 yrs.",
"value": "148",
"direction": "up"
}]
so the json for this may be something like
$(document).ready(function() {
function maskMaker(el) {
var backcolor = $(el).data("color");
var backopacity = $(el).data("opacity");
// Set the main elements for the series chart
var svgroot = d3.select($(el)[0]).append("svg");
var mask = svgroot
.append("defs")
.append("mask")
.attr("id", "myMask");
mask.append("rect")
.attr("x", 0)
.attr("y", 0)
.attr("width", "1200px")
.attr("height", 500)
.style("fill", "white")
.style("opacity", backopacity);
mask.append("circle")
.attr("cx", 550)

You need to do several things:
In SVG DOM have the label and the pointer after the rectangle with the mask (or the rectangle itself before them). This will make them topmost. There is no z-index in SVG.
Add a declaration of the marker to the same 'defs' node at the beginning of SVG
Set pointer target values d.cx and d.cy (in the example below I set them to ordinary values)
Implement enter-update-exit pattern differently. In your example code with comments '__ update' will only be executed for existing elements in the selection, whereas it is empty on first run. See https://bl.ocks.org/mbostock/3808218 on how to merge operations on just added elements and already existing ones.
labels.enter()
.append("text")
.attr("text-anchor", "middle")
//__ update
//labels
.attr("x", function(d) {
return d.x;
})
...

D3 js selectAll each doesn't iterate

I am trying to implement the FishEye lens (Cartesian) in my scatterplot.
I am trying to follow this approach, but apparently my selector already fails.
I have my FishEye defined as
var fisheye = d3.fisheye.circular().radius(120);
svg.on("mousemove", function() {
fisheye.focus(d3.mouse(this));
console.log("here " + points.selectAll("circle").length);
points.selectAll("circle").each(function(d) {
console.log("aaa");
d.fisheye = fisheye(d);
/*points.selectAll("circle")
.each(function(d) {
console.log("???");
this.attr("cx", function(d) { return d.fisheye.x; })
this.attr("cy", function(d) { return d.fisheye.y; })
this.attr("r", function(d) { console.log("hype"); return 10; });
}); */
});
});
and my points is defined as
points = svg.append("g")
.attr("class", "point")
.selectAll("circle")
.data(dataset)
.enter()
.append("circle")
.attr("cx", function(d) { // Set the x position using the x-scale
return x(d.x);
})
.attr("cy", function(d) { // Set the y position using the y-scale
return y(d.y);
})
.attr("r", 5) // Set the radius of every point to 5
.on("mouseover", function(d) { // On mouse over show and set the tooltip
if(!isBrushing){
tooltip.transition()
.duration(200)
.style("opacity", 0.9);
tooltip.html(d.symbol + "<br/> (" + parseFloat(x(d.x)).toFixed(4)
+ ", " + parseFloat(y(d.y)).toFixed(4) + ")")
.style("left", (d3.event.pageX + 5) + "px")
.style("top", (d3.event.pageY - 28) + "px");
}
})
.on("mouseout", function(d) { // on mouseout, hide the tooltip.
tooltip.transition()
.duration(500)
.style("opacity", 0);
});
The console.log with "here" is spamming when I am moving the mouse, and shows the correct amount. Hwoever, the each loop is never executed as I do not see "aaa". I have also tried to just use selectAll("circle") but that doesn't work either.
What am I doing wrong and how can I get my FishEye to work?
