The attached fiddle shows that on zoom the blue rectangles resize with the scale as expected but the yellow rectangles don't! The main difference is that the yellow rectangles were added to a 'g' element with text included. Any ideas why?
https://jsfiddle.net/sjp700/u6rj20jc/1/
var group = svg.selectAll(".rectangle")
.data(data);
gEnter = group.enter()
.append("g")
.attr("class", "rectangle")
.attr("fill", "yellow")
.attr("transform", function (d) { return "translate(" + x(d.start) + "," + y(d.finish) + ")"; });
gEnter.append("rect")
.attr("class", "rectband")
.merge(gEnter)
.attr("width", 50)
.attr("height", 18)
//.attr("rx", 10)
//.attr("ry", 10)
.style("opacity", .5) // set the element opacity
.style("stroke", "black");
Your yellow rectangles and text is not contained in an element that the zoom is applied to. Simple fix is to append them to gMain (which is the element on which the zoom is applied):
var group = gMain
.selectAll(".rectangle")
.data(data);

My chart needs a label in the center of the donut that should not rotate when clicked.
https://codepen.io/scratchy303/pen/dyXMzrz
Can I append the label in a sibling "g"roup and rotate the arcs group?
Can I translate just the arcs rather than rotating the entire SVG?
What's the simplest solution?
var svg = d3.select("#pieChart").append("svg")
.attr("width", '100%')
.attr("height", '100%')
.attr('viewBox', '0 0 ' + Math.min(width, height) + ' ' + Math.min(width, height))
.attr('preserveAspectRatio', 'xMinYMin')
.append("g")
.attr("transform", "translate(" + radius + "," + height / 2 + ")")
.style("filter", "url(#drop-shadow)");
svg.append("g")
.append("text")
.attr("text-anchor", "middle")
.text("Donut Name");
I found a solution by counter-rotating my text. My biggest hurdle was simply traversing my SVG in D3.
//start by selecting the parent "g"roup and then you can select the text
d3.select(i.parentNode).select(".donut-label")
.transition()
.duration(1000)
.attr("transform", "rotate(" + (-angle) + ")");
I have appended some text to a map I am working on in d3, here is my code:
countriesGroup = svg
.append("g")
.attr("id", "map");
//add background
countriesGroup.append('rect')
.attr("x", 0)
.attr("y", 0)
.attr("width", w)
.attr("height", h);
//Draw countries
countries = countriesGroup.selectAll("path")
.data(j.features)
.enter()
...Draw country borders
//Create Timer Text
countriesGroup.append("text") <-----This worked
.attr("transform", "translate(" + w/2 + "," + h/2 + ")")
.style("fill", "#ff0000")
.text("This is a test");
//Create Timer Text
svg.append("text") <-----This didn't
.attr("transform", "translate(" + w/2 + "," + h/2 + ")")
.style("fill", "#ff0000")
.text("This is a test");
I initially tried appending the Timer text directly to svg but that did not work. When I later tried appending it directly to the countriesGroup group, this worked. How come the text was only able to render when appended to the group, but not when appended directly to the svg?
I'm trying to draw vertical labels for the heatmap that I'm working. I'm using the example from http://bl.ocks.org/tjdecke/5558084. Here is the part of the code that I've changed:
var timeLabels = svg.selectAll(".timeLabel")
.data(ife_nr)
.enter().append("text")
.text(function(d) {
return d;
})
.attr("x", function(d, i) {
return (i * gridSize);
})
.attr("y", 0)
//.style("text-anchor", "middle")
//.attr("transform", "translate(" + gridSize / 2 + '-5' + ")")
.attr("transform", "translate(" + gridSize/2 + '-8' + "), rotate(-90)")
.attr("class", function(d, i) {
return ((i >= 0) ? "timeLabel mono axis axis-worktime" : "timeLabel mono axis");
});
But it appears the labels seems to be stacked on top one another on top of the first grid. How can I edit this code to get the labels correctly displayed?
Two problems: first, the translate should have a comma separating the values:
"translate(" + gridSize/2 + ",-8), rotate(-90)")
Assuming that -8 is the y value for the translate. If you don't have a comma, the value inside the parenthesis should be just the x translation (If y is not provided, it is assumed to be zero). But even if there is actually no comma and all that gridSize/2 + '-8' is just the x value you still have a problem, because number plus string is a string. You'll have to clarify this point.
Besides that, for rotating the texts over their centres, you'll have to set the cx and cy of the rotate. Have a look at this demo:
var svg = d3.select("body")
.append("svg")
.attr("width", 400)
.attr("height", 100);
var texts = svg.selectAll(".texts")
.data(["foo", "bar", "baz"])
.enter()
.append("text");
texts.attr("y", 50)
.attr("x", function(d,i){ return 50 + 80*i})
.text(function(d){ return d});
texts.attr("transform", function(d,i){
return "rotate(-90 " + (50 + 80*i) + " 50)";
});

I am looking for a way to have a fixed position and width of a group in a d3.js chord diagram. Is there a way to do this?
This is how it is shown by default when drawing the chord diagram:
This is how I would like the top (1st group) to show (wider than the other groups and centered at the top):
If you a fixed data set then you know how much to rotate so that you get your desired position.
I applied rotation on this example:
http://bl.ocks.org/mbostock/4062006
So that it become very much of your proposed chart fiddle below:
http://jsfiddle.net/cyril123/L9s2dpxt/
To achieve this you will need to give rotation to the main g group like this:
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width / 2 + "," + height / 2 + ")rotate(100)");
//Rotating this by 100 degrees but this can be your choice depending on your dataset.
Next is the rotation of the text this is governed by this code
ticks.append("text")
.attr("x", 8)
.attr("dy", ".35em")
.attr("transform", function(d) { return d.angle > Math.PI ? "translate(16)" : null; })//I am just giving translate no rotation
.style("text-anchor", function(d) { return d.angle > Math.PI ? "end" : null; })
.text(function(d) { return d.label; });
I currently have a graph that has associated bar values displaying above each bar, but I'm having difficulty centering the value labels, due to not being able to fetch each text element's width.
This is how my graph is drawing at the moment:
All I need to do is to subtract half of each text element's width, but I can't seem to do so with the following Coffeescript:
#Drawing value labels
svg.selectAll("rect")
.data(data)
.enter()
.append("text")
.text((d)-> d.Total)
.attr("width", x.rangeBand())
.attr("x", (d)->
textWidth = d3.selectAll("text").attr("width")
x(d.Year) + (x.rangeBand() / 2) - (textWidth / 2)
)
.attr("y", (d)-> y(d.Total) - 5)
.attr("font-size", "10px")
.attr("font-family", "sans-serif")
#Drawing bars
svg.selectAll("rect")
.data(data)
.enter().append("rect")
.attr("class", "bar")
.attr("x", (d)-> x(d.Year))
.attr("width", x.rangeBand())
.attr("y", (d)-> y(d.Total))
.attr("height", (d)-> height - y(d.Total))
Is there a way that I can access each text element's width attribute to set a value to offset?
A perhaps simpler way is to use a text-anchor of middle with x set to the left side of the bar plus half the width of the bar:
svg.selectAll(".bar-label")
.data(data)
.enter().append("text")
.text((d)-> d.Total)
.attr("class", "bar-label")
.attr("text-anchor", "middle")
.attr("x", (d)-> x(d.Year) + x.rangeBand()/2)
.attr("y", (d)-> y(d.Total) - 5)
You can get the bounding box of the text and use those values to apply a transform to center it. An example for getting the bounding box is here. The code would look something like
.text(function(d) { return d.Total; })
.attr("x", function(d) {
return x(d.Year) + (x.rangeBand() / 2) - (this.getBBox().width / 2);
}
