My D3js sunburst chart is only displaying 2 layers of data even though there are more layers.
I want it to display all layers of data
A live version of the chart is here: D3 Chart
The code is below. please advise on how to make the chart display all of the layers of data.
I need to see more than just two layers.
export default function define(runtime, observer) {
const main = runtime.module();
main.variable(observer()).define(["md"], function(md){return(
md`# D3 Zoomable Sunburst

Click a node to zoom in, or click the center to zoom out.`

I've made a couple of changes, firstly making the example more minimal by removing hover and click events.
I needed to change the arc radius and the partition method as per this example, and took text positioning logic from this fiddle.
const width = 500,
radius = width / 2,
format = d3.format(",d");
const svg = d3.select('svg')
.attr("width", width)
.attr("height", width)
.style("font", "10px sans-serif");
const g = svg.append("g")
.attr("transform", `translate(${radius},${radius})`);
const arc = d3.arc()
.startAngle(d => d.x0)
.endAngle(d => d.x1)
.padAngle(d => Math.min((d.x1 - d.x0) / 2, 0.005))
.padRadius(radius)
.innerRadius(d => Math.sqrt(d.y0))
.outerRadius(d => Math.sqrt(d.y1) - 1);
d3.json("https://gist.githubusercontent.com/MargretWG/b3f9e0a383408c6e6a45fc652e83a26c/raw/8756e2320d05a774e96983234beff81b01409315/hierarchy.json").then(data => {

// for text it is the X axis.
var thetaDeg = (180 / Math.PI * (arc.startAngle()(d) + arc.endAngle()(d)) / 2 - 90);
// If we are rotating the text by more than 90 deg, then "flip" it.
// This is why "text-anchor", "middle" is important, otherwise, this "flip" would
// a little harder.
return (thetaDeg > 90) ? thetaDeg - 180 : thetaDeg;

I am trying to fill circles in waffle partially based on the data. It should show circles partially coloured. With my following code, I am getting black circles instead of partially coloured circles.
The clip-path I am trying to draw is incorrect or so.
Any help will be appreciated.
Thank you in advance!
const waffle = d3.select(waffleDiv)

I have a D3 chart but only want to show 3 ticks for the y-axis.
Depending on the data, I sometimes get 3, 4 or 5 ticks which makes it difficult for me to style with CSS.
Here is the full code:
// Create a new d3
var chart = d3.select('#analytics-chart').append('div').attr('class', 'chart');
chart.append('div').attr('class', 'y-axis');
chart.append('div').attr('class', 'bars-and-x-axis');
var barMargin = '0 2px',
min = 0,
max = d3.max(data, function(d) {
return parseInt(d.value, 10);
});
var bars = d3.selectAll('.bars-and-x-axis').append('div').attr('class', 'bars'),
xaxis = d3.selectAll('.bars-and-x-axis').append('div').attr('class', 'x-axis'),
yaxis = d3.selectAll('.y-axis'),
xScale = d3.scale.linear().domain([1, data.length]),
yScale = d3.scale.linear().range(0, 100).domain([min, max]),
barWrapper = bars.selectAll()
.data(data.map(function(d) {
return d.value;
}))
.enter()
.append('div')
.attr('class', function(d, i) {
if (d == 0) {
return 'chart-data-wrapper empty';
} else {
return 'chart-data-wrapper';
}
}).style('margin', barMargin);
var bar = barWrapper.append('div').attr('class', 'chart-data-bar')
.style('height', function(d) {
return Math.ceil((d - min) / (max - min) * 100) + 'px';
})
.append('div')
.attr('class', 'tooltip')
.attr('style', function(d, i) {
return 'left: ' + Math.ceil(i / data.length * 100) + '%; transform: translateX(-' + Math.ceil(i / data.length * 100) + '%); ';
})
.append('p')
.text(function(d, i) {
return data[i].date;
})
.append('p')
.attr('class', 'data')
.text(function(d, i) {
return data[i].content;
});
xaxis.selectAll()
.data(xScale.ticks(12))
.enter()
.append('div')
.attr('class', 'x-axis-mark');
yaxis.selectAll()
.data(yScale.ticks(3))
.enter()
.insert('small', ':first-child')
.attr('class', 'label')
.text(function(d, i) {
if (d > 999) {
d = d / 1000 + 'k';
}
return d;
});
var tick = d3.selectAll('.x-axis-mark')
.append('div')
.attr('class', function(d, i) {
if (i % 3 == 1) {
return 'x-axis-tick-with-label';
} else {
return 'x-axis-tick';
}
});
var label = d3.selectAll('.x-axis-mark')
.append('small')
.attr('class', 'label')
.text(function(d, i) {
var format = d3.time.format('%b');
return data[i].xlabel;
})
.attr('class', function(d, i) {
if (i % 3 != 1) {
d3.select(this).remove();
}
});
Edit - I've added the full code and attached an image of the working example below:
I was able to replace yScale.ticks(3) in .data(yScale.ticks(3)) with my own math function that returns an array of values to create the tick values.
I am new for D3. How can I add an arrow to the beginning and to the end of this line?
var x = 100;
var y = 100;
var canvas = d3.select("#canvasContainer")
.append("svg")
.attr("width", 600)
.attr("height", 500);
var line1 = canvas.append("line")
.attr("x1", x)
.attr("y1", y)
.attr("x2", x)
.attr("y2", y + 50)
.attr("stroke", "red")
.attr("stroke-width", "3");
All you need is:
svg
.append('svg:defs')
.append('svg:marker')
.attr('id', 'triangle')
.attr('refX', 6)
.attr('refY', 6)
.attr('markerWidth', 30)
.attr('markerHeight', 30)
.attr('markerUnits', 'userSpaceOnUse')
.attr('orient', 'auto')
.append('path')
.attr('d', 'M 0 0 12 6 0 12 3 6')
.style('fill', 'black');
Next:
const pathNodes = svg
.append('path')
.datum(path)
.attr('d', line)
.attr('fill', 'none')
.attr('stroke-width', '3')
.attr('stroke', (d) => d.color)
.attr('marker-end', 'url(#triangle)');
Or with animation in my case:
const arrow = svg
.append('svg:path')
.attr('d', 'M 0 0 12 6 0 12 3 6')
.attr('fill', 'black');
arrow
.transition()
.duration(2000)
.delay(1500)
.ease(d3.easeLinear)
.attrTween('transform', this.arrowAnimation(pathNodes.node()));
arrowAnimation(path) => {
const l = path.getTotalLength();
let prevX = 0;
let prevY = 0;
return (d, i, a) => {
return (t) => {
const p = path.getPointAtLength(t * l);
const deltaY = prevY - p.y;
const deltaX = prevX - p.x;
prevY = p.y;
prevX = p.x;
let rotTran;
if (deltaY === 0) {
if (deltaX > 0) {
rotTran = 'rotate(-180)';
} else {
rotTran = 'rotate(180)';
}
} else if (deltaX === 0) {
if (deltaY > 0) {
rotTran = 'rotate(-90)';
} else {
rotTran = 'rotate(90)';
}
} else {
rotTran = 'rotate(0)';
}
return 'translate(' + p.x + ',' + p.y + ') ' + rotTran;
};
};
}
I've got a fairly simple reusable chart built in D3.js -- some circles and some text.
I'm struggling to figure out how to update the chart with new data, without redrawing the entire chart.
With the current script, I can see that the new data is bound to the svg element, but none of the data-driven text or attributes is updating. Why isn't the chart updating?
Here's a fiddle: http://jsfiddle.net/rolfsf/em5kL/1/
I'm calling the chart like this:
d3.select('#clusters')
.datum({
Name: 'Total Widgets',
Value: 224,
Clusters: [
['Other', 45],
['FooBars', 30],
['Foos', 50],
['Bars', 124],
['BarFoos', 0]
]
})
.call( clusterChart() );
When the button is clicked, I'm simply calling the chart again, with different data:
$("#doSomething").on("click", function(){
d3.select('#clusters')
.datum({
Name: 'Total Widgets',
Value: 122,
Clusters: [
['Other', 14],
['FooBars', 60],
['Foos', 22],
['Bars', 100],
['BarFoos', 5]
]
})
.call( clusterChart() );
});
The chart script:
function clusterChart() {
var width = 450,
margin = 0,
radiusAll = 72,
maxRadius = radiusAll - 5,
r = d3.scale.linear(),
padding = 1,
height = 3 * (radiusAll*2 + padding),
startAngle = Math.PI / 2,
onTotalMouseOver = null,
onTotalClick = null,
onClusterMouseOver = null,
onClusterClick = null;
val = function(d){return d};
function chart(selection) {
selection.each(function(data) {
var cx = width / 2,
cy = height / 2,
stepAngle = 2 * Math.PI / data.Clusters.length,
outerRadius = 2*radiusAll + padding;
r = d3.scale.linear()
.domain([0, d3.max(data.Clusters, function(d){return d[1];})])
.range([50, maxRadius]);
var svg = d3.select(this).selectAll("svg")
.data([data])
.enter().append("svg");
//enter
var totalCircle = svg.append("circle")
.attr("class", "total-cluster")
.attr('cx', cx)

.attr('y', cy + 4);
var clusters = svg.selectAll('circle.cluster')

.attr('y', function(d, i) { return cy + Math.sin(startAngle + stepAngle * i) * outerRadius - 4; });
//update with data
svg .selectAll('text.total-value')
.text(val(data.Value));
svg .selectAll('text.total-name')
.text(val(data.Name));
clusters
.attr('class', function(d, i) {
if(d[1] === 0){ return 'cluster empty'}
else {return 'cluster'}
})
.attr("r", function (d, i) { return r(d[1]); });
clusterValues
.text(function(d) { return d[1] });
clusterNames
.text(function(d, i) { return d[0] });
$(window).resize(function() {
var w = $('.cluster-chart').width(); //make this more generic
svg.attr("width", w);
svg.attr("height", w * height / width);
});
});
}
chart.width = function(_) {
if (!arguments.length) return width;
width = _;
return chart;
};
chart.onClusterClick = function(_) {
if (!arguments.length) return onClusterClick;
onClusterClick = _;
return chart;
};
return chart;
}
I have applied the enter/update/exit pattern across all relevant svg elements (including the svg itself). Here is an example segment:
var clusterValues = svg.selectAll("text.cluster-value")
.data(data.Clusters,function(d){ return d[1];});
clusterValues.exit().remove();
clusterValues
.enter().append('text')
.attr('class', 'cluster-value');
...
Here is a complete FIDDLE with all parts working.
NOTE: I tried to touch your code as little as possible since you have carefully gone about applying a re-usable approach. This the reason why the enter/update/exit pattern is a bit different between the total circle (and text), and the other circles (and text). I might have gone about this using a svg:g element to group each circle and associated text.
