Display Data from JSON .on("mouseover", How? - javascript
What I'm trying to do is get a function that when I move my mouse over the Map(USA) that is drawn with a d3.json file that this will show it's data which is stored in a CSV file.
What I'm having trouble with is that I don't know how to implement the mouseover function, because I don't know where I should reference towards.
This is my code. I have no idea how to do this. Any tips would be really appreciated.

You must add 3 events mousedown, mousemove, mouseup
const target = document.getElementsByTagName("SVG");
// or by id
const target = document.getElementsById("someid");
target.addEventListener('mousedown', () => {
console.log('mousedown');
});
target.addEventListener('mousemove', () => {
console.log('mousemove');
});
target.addEventListener('mouseup', () => {
console.log('mouseup');
});
but I thing d3.js handle all this, check the official documentation.

Using D3 for painting grid cells multiple times?
I have a tsv file with 100000+ lines and 3 columns: time(ascending, nanoseconds);object;color. In this file each object appears multiple times with different color and time. And i have a grid, where each cell represents one of the objects (about 500+) and their actual color.
Here is the Code:

i want to start the visualisation (like youtube: variable speed, slider, possible to play/pause, back and forth) and while time is running it should always check the time in the file if an object needs to be updated. so, e.g. beeing at 45 seconds and all objects should represent their latest color update until that time.
As a newbie in general but especially in D3 i am wondering if D3 is a good choice and if so how my approach should look like or if i shouldn't use D3 with these requirements at all? I didn't figure out to fully understand update,enter and exit, yet but it feels like it should be the answer. If so i have no clue how the approach for "rewinding" should look like, since it shouldn't delete an object but repaint it with its latest color before the chosen time.
Here is the latest working example on plunker with a very small dataset for better understanding. It is supposed to look like this (missing the whole slider functionality like in youtube). But it is not supposed to use setTimeout for the moments of painting. I want to use "real time" from the tsv file.
As best fit got these sources: slider, grid.
With slider i am having trouble to change the Date approach into my nanoseconds.
Do you have some help if D3 will work and how to approach all of this since i am a bit lost?
PS: First question for me: Any suggestion for a better title of this question? I am happy to edit my question to make it more comfortable for everyone.
D3.js Problem rendering barchart with object data
I have the following script for rendering a simple barchart in D3.js. I have been able to render charts ok up until a point.
I have this data below which I am struggling to insert into my chart, there is no specific key I can call upon and I'm really confused how I would insert all of these into my chart.
Object { "food-environmental-science": 0, "art-media-research": 0, .....}
I have a seperate file for the HTML (only a snippet):
var barchart1 = barchart("#otherchart");
function clickScatter(d){
var unitOfAssessment = d.UoAString;
click = d.environment.topicWeights
renderTopicWeights(click)
}
function renderTopicWeights(clickedPoint){

format your input data into object like {key:"",value:""} and pass this into d3 so that they can understand and render chart.
var input = {'a':1,"b":2};
function parseData(input){
return Object.keys(input).reduce(function(output, key){
output.push({"key":key,"value":input[key]});
return output;
},[])
}
console.log(parseData(input));
// [{"key":"a","value":1},{"key":"b","value":2}]

d3js v5 + Topojson v3 Show/Hide element on click legend
I would like this reverse action http://bl.ocks.org/d3noob/5d621a60e2d1d02086bf. When I click on an item of my legend, I want focus all elements of the map within these class.
However, how isolate just one class compared to others?
For example in this image, just show elements where the value is included between 23500 and 29000 and hide other elements.
I suggest to 1/ filter data and 2/ fill with the same color these elements but surely it's easier.

Your instincts will work - filter the path data according to the color:
features.filter(function(feature) {
return color(feature.properties["value0"]) == d;
})
I saved your feature paths in the variable features in the plunkrs below
As the datum of each legend entry is a color, we can just filter the paths based on which datum would produce the same color when scaled. We could alternatively give class names or apply other indicators to filter.
Color the filtered paths on the event, revert all paths on some sort anti-event. Since you haven't said what will reset the map, I'll assume if you click on the same legend entry twice in a row the map should reset (this lets you toggle between each legend entry). To do so we'll need to keep track of which legend entry is currently in focus:
var highlighted = "";
Then we just listen for a click event on the legend entry and:
.on("click",function(d,i) {
highlighted = ""; //reset
// revert map back to default state
}
else {
highlighted = d;
// filter features to highlight certain ones.
})
Altogether that might look like:
.on("click",function(d,i) {
// clicking an active entry: reset:
if(highlighted == d) {
// reset opacity on each path:
features.style("opacity",1);
// reset legend entries' fills:
legend.selectAll("rect")
.style("fill",function(d) { return d; });
// reset highlight variable since nothing is highlighted
highlighted = "";
}
// clicking a different entry: highlight that entry:
else {
//update highlighted variable
highlighted = d;
// set opacity low for all features, filter for chosen features and style accordingly:
features.style("opacity",0.2)
.filter(function(f) {
return color(f.properties["value0"]) == d;
})
.style("opacity",1);
// hollow legend entries
legend.selectAll("rect")
.style("fill","white")
// fill selected option:
d3.select(this).select("rect")
.style("fill",function(d) { return d;});
}
})
Which looks something like:
(I'm formatting the legend entries to show what is highlighted - I changed your stroke to accomodate this)
Here's an updated plunkr.
If you want to be able to toggle multiple legend items at once, then the logic gets a bit more detailed and the highlighted variable becomes an array
As an alternative with mouseover/off events rather than clicks (so no need to track what is actively shown), here's a slightly different approach using the same principles: plunkr
D3.js adding/removing data pie chart slices
I have an input control that should on the key up event on the control either add or subtract a slice from a pie chart depending on if you hit the left or right arrow keys. It doesn't really work as expected because it seems that the new pie slice is sometimes being taken out of existing pie slices and the entire chart is not being recalculated. I'm not sure if I'm messing up the enter or the exit selection. Help is appreciated, TIA.
fiddle http://jsfiddle.net/jaqj3usb/
pertinent code
function removeSlices(n){
var i = -1;
while(++i < n){
data.pop();
}
paths.data(pie(data)).exit().remove();
paths.data(pie(data)).attr('d',arc).attr('transform','translate(100,200)')
}
function changeSlices(){
console.log('woot');
var shouldAddSlice = d3.event.target.valueAsNumber > data.length,
numDifference = Math.abs(data.length - d3.event.target.valueAsNumber);
if(shouldAddSlice){
addSlices(numDifference);
}
else{
removeSlices(numDifference);
}
}
sliceSlider.on('keyup',changeSlices);
I am also new to D3js, trying to learn. I used jQuery for handling keyup events. I did some changes, so left arrow adds and right arrow subtracts slices.
passed jquery as in argument to self executing function
(function(d3, $) {
})(window.d3, $);
In addSlices() changed
paths
.data(pie(data))
.enter()
.append('path')
.attr('d',arc)
.attr('transform','translate(100,200)')
.attr('fill',function(d,i){
return colors[i]
});
to
paths.data(pie([])).exit().remove();
paths = svg.selectAll('path').append('g')
.data(pie(data))
.enter()
.append('path')
.attr('d',arc)
.attr('transform','translate(100,200)')
.attr('fill',function(d,i){
return colors[i];
});
above code deletes and redraws the pie.
full code:
(function(d3,$){
var svg = d3.select('body').append('svg').attr({
height: 500,
width: 500,
id: 'mySvg'
});
var data = [10,20,30];
var sliceSlider = d3.select('body').append('input').attr({
type: 'range',
max: 10,
min: 1,
value : data.length
});
var colors=['orange','blue','steelblue','green','red','yellow','purple','pink','indigo'];
var pie = d3.layout.pie();
pie.value(function(d){ return d});
var arc = d3.svg.arc().innerRadius(10).outerRadius(100);
var paths = svg.selectAll('path').append('g')
.data(pie(data))
.enter()
.append('path')
.attr('d',arc)
.attr('transform','translate(100,200)')
.attr('fill',function(d,i){
return colors[i]
});
function addSlices(n){
var i = -1;
function randomBetween(min,max){
return Math.floor(Math.random()*(max-min+1)+min);
}
while(++i <n){
data.push(randomBetween(10,50));
}
paths.data(pie([])).exit().remove();
paths = svg.selectAll('path').append('g')
.data(pie(data))
.enter()
.append('path')
.attr('d',arc)
.attr('transform','translate(100,200)')
.attr('fill',function(d,i){
return colors[i];
});
}
function removeSlices(n){
var i = -1;
while(++i < n){
data.pop();
}
paths.data(pie(data)).exit().remove();
paths.data(pie(data)).attr('d',arc).attr('transform','translate(100,200)');
}
function changeSlices(){
console.log('woot');
var max=$("input[type='range']").attr("max")-data.length;
var shouldAddSlice = max > data.length;
if(shouldAddSlice){
addSlices(1);
}
}
$(document).keyup(function(e) {
switch(e.which) {
case 37: // left
changeSlices();
break;
case 39: // right
removeSlices(1);
break;
default: return; // exit this handler for other keys
}
e.preventDefault(); // prevent the default action (scroll / move caret)
});
})(window.d3,$);
example : http://jsfiddle.net/jaqj3usb/2/
Here is first variant (I think this is correct), base on this please add comments because you are not computing correctly from the start svg's added to the page.
You can remove individual pie slice like this but this will is not update correct your plate:
svg.selectAll('path')[0][pos].remove();
where pos 0 < data.length (in your original code not correct)
Adding in this way you are overlapping unmoved slices:
paths
.data(pie(data))
.enter()
.append('path')
.attr('d',arc)
.attr('transform','translate(100,200)')
.attr('fill',function(d,i){
return colors[i]
});

In the same way that you use this code:
svg.selectAll('path').append('g')
.data(pie(data))
.enter()
.append('path')
You can use:
svg.selectAll('path').append('g')
.data(pie(data))
.exit()
.remove()
This should remove pie graph elements which no longer have data associated with them.
how to do a simple looping carousel of svg:g elements with D3.js
I am trying to make a scrollable list that is part of a bigger d3.js generated chart. clicking on list item acivates changes in the rest of the chart.
How would you make a simple animated looping carousel of svg:g elements with D3.js using the reusable chart pattern ?
Wired to jQuery-mousewheel or some forward and back buttons for example.
http://jsbin.com/igopix/2/edit
NameLoop = function () {
var scroll = 0;
function chart(selection) {
selection.each(function (data) {
var len = data.length,
scroll = scroll % len + len; // keep scroll between 0 <-> len
var nameNodes = d3.select(this).selectAll("g")
.data(data, function(d){return d.ID;} );
var nameNodesEnter = nameNodes.enter().append("g")
.attr("class", "nameNode")
.attr("transform", function(d, i) {
// implement scroll here ??
return "translate(30," + (i+1)*20 + ")";
})
.append("text")
.text(function(d){return d.ID;});
});
return chart;
}
chart.scroll = function(_) {
if (!arguments.length) return scroll;
scroll = _;
return chart;
};
return chart;
};
data = [{ID:"A"},{ID:"B"},{ID:"C"},{ID:"D"},{ID:"E"}];
var svg = d3.select("body").append("svg")
.attr("width", 200)
.attr("height",200)
.attr("id","svg");
var nameloop = NameLoop();
d3.select("#svg").datum(data).call(nameloop);
var body = d3.select("body").append("div");
body.append("span").on("click",function(d){ scroll(1) }).html("forward ");
body.append("span").on("click",function(d){ scroll(-1) }).html("back");
