I'm using d3 to draw a chart (I'm using thix example: https://gist.github.com/keiranlovett/8766741). I need to add a link. I'm adding text and I'm trying to make it a link, but it's not appearing as a link (I'm using IE 11):
svg.append("g") //without doing this, impossible to put grid lines behind text
.attr({
xmlns: "http://www.w3.org/2000/svg",
xlink: "http://www.w3.org/1999/xlink",
width: 100,
height: 300
})
.attr({ "xlink:href": "#" })
.on("mouseover", function (d, i) {
//alert('aaa');
d3.select(this)
.attr({ "xlink:href": "http://example.com/" + "eeeeeeeeeeeeeeeeeee" });
})
.selectAll("text")
.data(tasks)
.enter()
.append("text")
.text(function (d) {
if (ammendmentsLinks.indexOf(d.contract) < 0) {
ammendmentsLinks = ammendmentsLinks + d.contract + ";";
return d.contract;
//return "";
}
else {
return "";
}
})
.attr("x", 20)
.attr("y", function (d, i) {
return i * 20;
})
.attr("font-size", 11)
.attr("text-anchor", "start")
.attr("text-height", 14)
.on("click", function (d) {
return click(d.contract);
});
I also added some lines of code from http://jsfiddle.net/christopheviau/B9zcF/ to make the text a link but it's not working.
How to make my text a link?
Try changing the following line:
d3.select(this)
.attr({ "xlink:href": "http://example.com/" + "eeeeeeeeeeeeeeeeeee" });
to
d3.select(this)
.wrap("<a xlink:href \"http://example.com/\"></a>")
.text("eeeeeeeeeeeeeeeeeee");
and make sure the <svg> tag has xmlns:xlink="http://www.w3.org/1999/xlink" specified.
This is a good solution too:
d3.select(this)
.text(d)
.on("click", function() { window.open("https://www.random.com/" + d ); });

I have a script in which I make txts in the following way:
texts = svg.selectAll(null)
.data(data)
.enter()
.append('text')
.attr("text-anchor", "middle")
.text(function(d) {
return d.abbreviation;
})
.attr("pointer-events", "none")
.attr("font-family", "sans-serif")
.attr("font-size", "10px")
.attr("fill", "black");
texts.each(function(d) {
console.log(this.getComputedTextLength());
d.size = this.getComputedTextLength() / 2 ;
});
simulation.nodes(data).on("tick", function() {
circles.attr("cx", function(d) {
return d.x = Math.max(20, Math.min(width - 20, d.x));
})
.attr("cy", function(d) {
return d.y = Math.max(20, Math.min(height - 20, d.y));
})
texts.attr("x", function(d) {
return d.x;
})
.attr("y", function(d) {
return d.y;
});
});
I am using property abbreviation in data to put text over the bubbles but I want to replace all spaces in input with new line character.
I tried some soutions like given at this link: How to linebreak an svg text in javascript?
but all texts go to left most corner or if I remove the .attr("x", 0) property from this, then the alignment of texts in not right. See picture below:
"State" should come directly below "Iowa"
Updated script:
texts = svg.selectAll(null)
.data(data)
.enter()
.append('text')
.attr("text-anchor", "middle")
.each(function (d) {
var arr = d.abbreviation.split(" ");
for (i = 0; i < arr.length; i++) {
d3.select(this).append("tspan")
.text(arr[i])
.attr("dy", i ? "1.2em" : 0)
.attr("text-anchor", "middle")
.attr("class", "tspan" + i);
}
})
.attr("pointer-events", "none")
.attr("font-family", "sans-serif")
.attr("font-size", "10px")
.attr("fill", "black");
What should I do to make the alignment right or is there any other way to do this?
There are different ways to fix this. An easy one is appending the <tspan> to a <g> element, setting all their x properties to 0 and text-anchor to middle.
Have a look at the demo:
var svg = d3.select("svg");
var data = [{
text: "some text"
}, {
text: "a longer text here"
}, {
text: "an even longer text here"
}, {
text: "short text"
}, {
text: "a long text"
}];
var texts = svg.selectAll(null)
.data(data)
.enter()
.append("g");
texts.append("text")
.attr("text-anchor", "middle")
.each(function(d) {
var arr = d.text.split(" ");
d3.select(this).selectAll(null)
.data(arr)
.enter()
.append("tspan")
.attr("text-anchor", "middle")
.attr("x", 0)
.attr("dy", function(d, i) {
return "1.2em"
})
.text(String)
})
var simulation = d3.forceSimulation(data)
.force("center", d3.forceCenter(200, 100))
.force("collide", d3.forceCollide(40))
.on("tick", tick);
function tick() {
texts.attr("transform", function(d) {
return "translate(" + d.x + "," + d.y + ")"
})
}
<script src="https://d3js.org/d3.v4.min.js"></script>
<svg width="400" height="250"></svg>
PS: Don't use that for loop inside the each. That's not idiomatic D3. Instead of that, just use an enter selection (refer to the demo to see how to do it).
script type="text/javascript">
d3.csv("mydata.csv", function(data){
var svgcontainer = d3.select("body").append("svg")
.attr("width",500)
.attr("height",500)

.data(data)
.enter()
.append("rect")
.attr("width" ,function (d) { return d.age * 10;})

})
I have to append text in my d3.js code but it's not displaying text.I am new to d3.js so please any one help me. Here is my code-
From the first observation i will get to know the issue related with the text element position in svg. In SVG Coordinate positions are very important to achieve the graphical representation. In above code snippet x and y positions are missing. sample code below:-
svgcontainer.append("text")
.attr("x", function(d) { return x(d.value) - 3; })
.attr("y", barHeight / 2)
.attr("dy", ".35em")
.text(function(d) { return d.value; });
Example
I've got a legend, with colored rectangles...
I'd like to replace the rectangles with symbols (i.e., circle, cross, diamond, square). I can't figure out how to do that.
I've been using variations of .attr("d", d3.svg.symbol().type('circle'). For instance, I tried:
legendRect
.attr("d", d3.svg.symbol().type(function (d) { return d[2] })
and I tried:
legendRect.append("svg:path")
.attr("d", d3.svg.symbol().type((d: any) => { return d[2] }))
d[2] is "supposed to be" pulling from legendData, as shown in the below code example...like it does with d[1] for the fill.
But I don't ever see anything change.
Here's the code I'm using for the legend, without the symbol stuff, below. What am I doing wrong and how can I change the rectangles to symbols? Where do I need to add what?
var legendData = [["OA", "yellow", "circle"], ["OI", "blue", "cross"], ["RARC", "green", "diamond"], ["CAPE", "red", "square"], ["Other", "black", "triangleDown"]];
var legend = this.svg.append("g")
.attr("class", "legend")
.attr("height", 0)
.attr("width", 0)
.attr('transform', 'translate(-20,250)');
var legendRect = legend.selectAll('rect').data(legendData);
legendRect.enter()
.append("rect")
.attr("x", width - 65)
.attr("width", 10)
.attr("height", 10)
;
legendRect
.attr("y", function (d, i) {
return i * 20;
})
.style("fill", function (d) {
return d[1];
})
var legendText = legend.selectAll('text').data(legendData);
legendText.enter()
.append("text")
.attr("x", width - 52);
legendText
.attr("y", function (d, i) {
return i * 20 + 9;
})
.text(function (d) {
return d[0];
});
Here's how I would code it. Notice, that I data-bind to a wrapper g element and then place the symbol and text into it for each legend item. You can then position the g instead of positioning the text and "symbol" separately. This also removes the need for double-binding the data.
var legendData = [["OA", "yellow", "circle"], ["OI", "blue", "cross"], ["RARC", "green", "diamond"], ["CAPE", "red", "square"], ["Other", "black", "triangleDown"]];
var svg = d3.select('body').append('svg').attr('width', 500).attr('height', 500);
var legend = svg.append('g')
.attr("class", "legend")
.attr("height", 0)
.attr("width", 0)
.attr('transform', 'translate(20,20)');
var legendRect = legend
.selectAll('g')
.data(legendData);
var legendRectE = legendRect.enter()
.append("g")
.attr("transform", function(d,i){
return 'translate(0, ' + (i * 20) + ')';
});
legendRectE
.append('path')
.attr("d", d3.svg.symbol().type((d) => { return d[2] }))
.style("fill", function (d) {
return d[1];
});
legendRectE
.append("text")
.attr("x", 10)
.attr("y", 5)
.text(function (d) {
return d[0];
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/3.4.11/d3.min.js"></script>
This is a implementation which uses symbols for your legend. You can use the symbols like the following:
svg.selectAll('.symbol')
.data(legendData)
.enter()
.append('path')
.attr('transform', function(d, i) {
return 'translate(' + (20) + ',' + ((i * 20) + 10) + ')';
})
.attr('d', d3.symbol().type(function(d, i) {
if (d[2] === "circle") {
return d3.symbolCircle;
} else if (d[2] === "cross") {
return d3.symbolCross;
} else if (d[2] === "diamond") {
return d3.symbolDiamond;
} else if (d[2] === "square") {
return d3.symbolSquare;
} else {
return d3.symbolTriangle;
}
})
.size(100))
.style("fill", function(d) {
return d[1];
});
Then you can set your legend labels like the following:
svg.selectAll('.label')
.data(legendData)
.enter()
.append('text')
.attr("x", "40")
.attr("y", function(d, i){ return ((i * 20)+15);})
.text(function(d) {
return d[0];
});
Check fiddle here - https://jsfiddle.net/zoxckLe3/
P.S. - Above solution uses d3 v4. To achieve the same in v3, use the following line .attr('d', d3.svg.symbol().type(function(d){return d[2];})) instead of the part where I match d[2] to the symbol name.
For adding image icons, you can use below code.
legend.append("**image**")
.attr("x", 890)
.attr("y", 70)
.attr("width", 20)
.attr("height", 18)
.attr("xlink:href",function (d) {
**return "../assets/images/dev/"+d+".png";**
})
This works for me..
I am trying to add some text from the name field in my JSON file to each bubble in a cluster.
https://plnkr.co/edit/hwxxG34Z2wYZ0bc51Hgu?p=preview
I have added what I thought was correct attributes to the nodes with
node.append("text")
.text(function (d) {
return d.name;
})
.attr("dx", -10)
.attr("dy", "5em")
.text(function (d) {
return d.name
})
.style("stroke", "white");
function tick(e) {
node.each(cluster(10 * e.alpha * e.alpha))
.each(collide(.5))
.attr("transform", function (d) {
var k = "translate(" + d.x + "," + d.y + ")";
return k;
})
}
Everything works fine except the labels.
What am I missing here?
Thanks
Kev
For that you will need to make a group like this:
var node = svg.selectAll("g")
.data(nodes)
.enter().append("g").call(force.drag);//add drag to the group
To the group add circle.
var circles = node.append("circle")
.style("fill", function(d) {
return color(d.cluster);
})
To the group add text:
node.append("text")
.text(function(d) {
return d.name;
})
.attr("dx", -10)
.text(function(d) {
return d.name
})
.style("stroke", "white");
Add tween to the circle in group like this:
node.selectAll("circle").transition()
.duration(750)
.delay(function(d, i) {
return i * 5;
})
.attrTween("r", function(d) {
var i = d3.interpolate(0, d.radius);
return function(t) {
return d.radius = i(t);
};
});
Now the tick method will translate the group and with the group the circle and text will take its position.
working code here
The problem: a text SVG element cannot be child of a circle SVG element.
The solution is creating another selection for the texts:
var nodeText = svg.selectAll(".nodeText")
.data(nodes)
.enter().append("text")
.text(function (d) {
return d.name;
})
.attr("text-anchor", "middle")
.style("stroke", "white")
.call(force.drag);
Here is the plunker: https://plnkr.co/edit/qnx7CQox0ge89zBL9jxc?p=preview
First time using d3.js and am experimenting with using this example: http://bl.ocks.org/christophermanning/1734663 in a site I'm making, but I want the fill of the shapes to be images instead of a purple color.
I think the relevant code is inside the update function as follows:
path = path.data(d3_geom_voronoi(vertices))
path.enter().append("path")
// drag node by dragging cell
.call(d3.behavior.drag()
.on("drag", function(d, i) {
vertices[i] = {x: vertices[i].x + d3.event.dx, y: vertices[i].y + d3.event.dy}
})
)
.style("fill", function(d, i) { return color(0) })
path.attr("d", function(d) { return "M" + d.join("L") + "Z"; })
.transition().duration(150).style("fill", function(d, i) { return color(d3.geom.polygon(d).area()) })
path.exit().remove();
So first I comment out..
.style("fill", function(d, i) { return color(d3.geom.polygon(d).area()) })
..so my image fill wont be overwritten on update, and then I need to replace..
.style("fill", function(d, i) { return color(0) })
..with "something", but before I replace it I define the image by adding..
var image = svg.append("image")
.attr("xlink:href", "http://lorempixel.com/g/400/400/")
.attr("x", 0)
.attr("y", 0)
.attr("width", 400)
.attr("height", 400)
.attr("id", "fillImage");
..before the update function, and then I've tried replacing the fill code with stuff like:
.style("fill", function(d, i) { return "url('#fillImage')" })
or
.style("fill", function(d, i) { return "url(#fillImage)" })
or
.style("fill", "url('#fillImage')")
or
.style("fill", "url(#fillImage)")
or all the same except using "attr" instead of "style", as well as not using an id but the image varible, so: image, image[0], image[0][0], image[0][0].outerHTML. But nothing seems to work, so any ideas?
