I'm trying to use a visualization as a selector on a D3 costum chart. I'm following the SDK documentation Here, and I can't make my example work.
Basicly I star by declaring "me" var and enable the "use as filter" option.
var me = this;
this.addUseAsFilterMenuItem();
Then, when appending de svg element, I add the clear and end selecion methods:
var g = d3.select(this.domNode).append("svg")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom)
.append("g")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")")
.on("click", function(d) {
if (event.target.classList.contains('bar')) {
me.clearSelections();
me.endSelections();
return true;
} else {
return true;
}
});
When getting data I use the hasSelection attribute:
var data = this.dataInterface.getRawData(mstrmojo.models.template.DataInterface.ENUM_RAW_DATA_FORMAT.TREE, {
hasSelection: true
}).children;
And when adding the "applyselection" method on my bars:
g.selectAll(".bar")
.data(data)
.enter()
.append("rect")
.attr("class", "bar")
.attr("x", function(d) {
return x(d.name);
})
.attr("y", function(d) {
return y(d.value);
})
.attr("height", function(d) {
return height - y(d.value);
})
.attr("width", x.rangeBand())
.style("fill", function(d) {
})
.on("click", function(d) {
me.applySelection(d.selection);
});
But it does not work. I manage to console d.selection on the bar click event, i it's undifined.
Can some one please give me a hand on this?
Thank you.
I was able to find out what was wrong with my code, after spending many many hours on this. The selection method must be called like this:
.on("click", function(d, i) {
me.applySelection(data[i].attributeSelector);
return true;
});

I'm trying to resize a grouped bar chart with a resize() function.
function resize(){
width = parseInt(d3.select(".c_chart").style("width"), 10);
x0.rangeRound([margin.left, width-margin.right]);
x1.rangeRound([margin.left,x0.bandwidth()-margin.right])
yAxis.tickSize(width);
svg.selectAll("rect")
.attr("x", function(d) { return x1(d.key); })
.attr("width", x1.bandwidth());
svg.selectAll(".x_axis")
.call(xAxis)
.selectAll("text")
.call(wrap, x0.bandwidth());
}
When I start to resize the window, x-axis is ok but the x-position of my recent don't "follow" the ticks of my x-axis.
Then, I suspect that the problem is due to x- attribute but how can I fix that?
Here is my code: https://plnkr.co/edit/XEoM7lsBvZQmY87Wz1SP?p=preview
Add a class (gbar) to the g containing the group
svg
.append("g")
.selectAll("g")
.data(data)
.enter().append("g")
.attr("transform", function(d) { return "translate(" + x0(d.categorie) + ",0)"; })
.attr("class", "gbar")
.selectAll("rect")
.data(function(d) { return keys.map(function(key) { return {key: key, value: d[key]}; }); })
.enter().append("rect")
.attr("x", function(d) { return x1(d.key); })
.attr("y", function(d) { return y(d.value); })
.attr("width", x1.bandwidth())
.attr("height", function(d) { return height-margin.bottom - y(d.value); })
.attr("fill", function(d) { return z(d.key); });
In the resize function update the translation
svg.selectAll(".gbar")
.attr("transform", function(d) { return "translate(" + x0(d.categorie) + ",0)"; });
and update the size of the SVG
svg
.attr("width",width)
.attr("height",height);
Don't take the margin in the x1 scale
const x1 = d3.scaleBand()
.padding(0.05)
.domain(keys)
//.rangeRound([margin.left,x0.bandwidth()-margin.right])
.rangeRound([0,x0.bandwidth()]);
// resize()
//x1.rangeRound([margin.left,x0.bandwidth()-margin.right])
x1.rangeRound([0,x0.bandwidth()])
The only thing left to fix is the y-axis grid line,........
I have created group bar chart by using D3.js. Each group has 2 bars. When any bar is clicked it must show some data using custom alert box. Now the bar can click and it shows data.
var state = svg.selectAll(".TestSuite")
.data(data)
.enter().append("g")
.attr("class", "TestSuite")
.on("click", function(d,i) {
if(i==0){
Alert.render(d3.select(this).data()[0].FalseStatements);
}else{
Alert.render(d3.select(this).data()[0].TrueStatements);
}
})
.attr("transform", function (d) {
return "translate(" + x0(d.TestSuite) + ",0)";
});
But data is vary according to clicked bars. So how to identify each single bar within a single group uniquely.
Here "if condition" that I used does not do the thing I want.How do I correct it?
Thank you.
(Suppose one group of bar consists two bars, one shows true count and other shows false count for a particular scenario. When we click the bar which shows true count then it should appear "TrueStatements" which is already have in data.using d3.select(this).data()[0].TrueStatements can do this. And also when someone click the bar which shows false count then it should appear "FalseStatements" which is already have in data.using d3.select(this).data()[0].FalseStatements can do this. My question is how do we identify the bar which shows true count and the bar which shows false count uniquely for do this task.)

I'm not sure I fully understand what you are asking yet but the best way to identifying any element/entity is with an id, something like the following:
d3.select(this).attr(id, function(d, i) {return 'bar_' + i});
Add this inside the iterative function where you are creating your bars. In this way you will be able to select them from anywhere in your code with a d3.select('#bar_1).
If you only want to identify each bar it would be something like this:
var state = svg.selectAll(".TestSuite")
.data(data)
.enter().append("g")
.attr("id", function(d,i) {return 'bar_' + i})
.attr("class", "TestSuite")
.on("click", function(d,i) {
if(i==0){
Alert.render(d3.select(this).data()[0].FalseStatements);
}else{
Alert.render(d3.select(this).data()[0].TrueStatements);
}
})
.attr("transform", function (d) {
return "translate(" + x0(d.TestSuite) + ",0)";
});
In the case that you would like to identify each bar with an Id related to its contents (true or false statements) I would suggest something like the following:
var state = svg.selectAll(".TestSuite")
.data(data)
.enter().append("g")
.attr("class", "TestSuite")
.on("click", function(d,i) {
var barId;
if(i==0){
barId = 'falseBar_' + i;
Alert.render(d3.select(this).data()[0].FalseStatements);
}else{
barId = 'trueBar_' + i;
Alert.render(d3.select(this).data()[0].TrueStatements);
}
d3.select(this).attr('id', barId);
})
.attr("transform", function (d) {
return "translate(" + x0(d.TestSuite) + ",0)";
});
In any case, this will assign an unique Id to every bar (i.e. "bar_25" or "falseBar_14") to each bar, giving you an ideal way to identify each bar.
EDIT: After OP showed me the actual code they are working with, the following are my suggestions for a solution (which are actually on the same lines as the code above).
The code you should actually be tinkering with is the one below the code you posted. It is where the actual bars are rendered:
state.selectAll("rect")
.data(function(d) { return d.ages; })
.enter().append("rect")
.attr("width", x1.rangeBand())
.attr("x", function(d) { return x1(d.name); })
.attr("y", function(d) { return y(d.value); })
.attr("height", function(d) { return height - y(d.value); })
.style("fill", function(d) { return color(d.name); });
My suggestion to add an id attribute to each bar would be the following:
state.selectAll("rect")
.data(function(d) { return d.ages; })
.enter().append("rect")
.attr("width", x1.rangeBand())
.attr("id", function(d, i) {return 'bar_' + i}) // <-- Edited line
.attr("x", function(d) { return x1(d.name); })
.attr("y", function(d) { return y(d.value); })
.attr("height", function(d) { return height - y(d.value); })
.style("fill", function(d) { return color(d.name); });
It is important that you understand why this, and not the code block you provided initially, is the pertinent one. As you well said, the first block renders each group of bars (hence the append("g") which stands for svg group). The second block starts with a append("rect") which means svg rectangle. This and other lines (i.e. style("fill")..., attr("x")... and attr("y")...) clearly give away that this block is the one dealing with the actual bars and not the groups.
I'm developing a stacked chart application.
http://jsfiddle.net/NYEaX/174/
I've placed it inside a jquery plugin to create multiple instances etc... different properties and eventually different data sources.
For now I am having problems animating the chart bars and the axis.
Animate bar code
animateBars: function(selector, data){
var w = $(selector).data("width");
var h = $(selector).data("height");
var margin = methods.getMargin(h);
methods.setDimensions(w, h, margin);
//methods.setX();
//methods.setY();
//methods.setDomain(data);
var initialHeight = 0;
//var svg = d3.select(selector + " .stackedchart");
var barholder = d3.select(selector + " .barholder");
var state = barholder.selectAll(".state")
.data(data)
.enter()
.append("g")
.attr("class", "g")
.attr("x", function(d) {
return methods.x(d.Label);
})
.attr("transform", function(d) {
return "translate(" + methods.x(d.Label) + ",0)";
});
var bar = state.selectAll("rect")
.data(function(d) {
return d.blocks;
});
// Enter
bar.enter()
.append("rect")
.attr("width", methods.x.rangeBand())
.attr("y", function(d) {
return methods.y(d.y1);
})
.attr("height", function(d) {
return methods.y(d.y0) - methods.y(d.y1);
})
.style("fill", function(d) {
return methods.color(d.name);
});
// Update
bar
.attr("y", function(d) {
return methods.y(d.y1);
})
.attr("height", function(d) {
return methods.y(d.y0) - methods.y(d.y1);
})
.transition()
.duration(500)
.attr("x", function(d) {
return methods.x(d.Label);
})
.attr("width", methods.x.rangeBand())
.attr("y", function(d) {
return methods.y(d.y1);
})
.attr("height", function(d) {
return methods.y(d.y0) - methods.y(d.y1);
});
// Exit
bar.exit()
.transition()
.duration(250)
.attr("y", function(d) {
return methods.y(d.y1);
})
.attr("height", function(d) {
return methods.y(d.y0) - methods.y(d.y1);
})
.remove();
}
One problem is that "state" is generated from the "enter()" method, so all your "bar" calls are only being executed when your "g.class" is being generated, not on update. Change this:
var state = barholder.selectAll(".state")
.data(data)
.enter()
.append("g")...
to this:
var state = barholder.selectAll(".state")
.data(data);
state.enter().append("g")...
See if that helps a bit. It doesn't seem to affect your fiddle, but you might be having problems other than d3. Try simplifying your fiddle and get the d3 stuff working by itself first.
I am using the word cloud library in D3 by Jason Davies. This is the normal code which I am using and works fine for creating the word clouds.
d3.layout.cloud().size([width, height])
.words(d3.zip(vis_words, vis_freq).map(function(d) {
return {text: d[0], size: wordScale(d[1]) };
}))
.padding(1)
.rotate(function() { return ~~(Math.random() * 2) * 0; })
.font("times")
.fontSize(function(d) { return d.size; })
.on("end", draw)
.start();
function draw(words) {
d3.select(curr_id).append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width/2 + "," + height/2 + ")")
.selectAll("text")
.data(words)
.enter()
.append("text")
.transition()
.delay(function(d,i){
return i*100;
})
.duration(1000)
.ease("elastic")
.style("font-size", function(d) { return d.size + "px"; })
.style("font-family", "times")
.style("fill", function(d, i) { return fill(i); })
.attr("text-anchor", "middle")
.attr("transform", function(d) {
return "translate(" + [d.x, d.y] + ")rotate(" + d.rotate + ")";
})
.text(function(d) { return d.text; });
}
I have a time slider to select a specific value, based on which words in the word cloud have different frequency(given by size) or some of the words are not there at all. I need to update without redrawing the entire word cloud which I am currently doing. In a way, I want to keep the position of words fixed and just updating their size and whether they exist based on the value selected on a slider?
Should I enter an update function in the function draw for this? Am certainly new to D3 and any help would be great?
To do this, you would select the existing text elements and set the font-size property for them. The code to do this looks like this:
d3.select("svg").selectAll("text")
.style("font-size", function(d, i) { // do something });
I am new to d3 and trying to figure out how to get a property ("NAME") to show up when hovering over a polygon in a map. I am aware that I should be doing something along the lines of .on("mouseover", function(d,i) { some function that returns properties.NAME } but can't figure out where to go from there. Here is the js as written, which just statically places the NAME property on each polygon:
<script>
var width = 950,
height = 650;
var projection = d3.geo.albers()
.scale(120000)
.center([22.85, 40.038]);
var path = d3.geo.path()
.projection(projection);
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height);
d3.json("newnabes.json", function(error, topology) {
var nabes = topojson.object(topology, topology.objects.temp);
svg.selectAll("path")
.data(nabes.geometries)
.enter().append("path")
.attr("d", path);
svg.selectAll(".subunit-label")
.data(nabes.geometries)
.enter().append("text")
.attr("class", function(d) { return "subunit-label " + d.id; })
.attr("transform", function(d) { return "translate(" + path.centroid(d) + ")"; })
.attr("dy", ".35em")
.text(function(d) { return d.properties.NAME; });
});
</script>
Here is a small chunck of the json
{"type":"Topology",
"transform":{
"scale":[0.00003242681758896625,0.000024882264664420337],
"translate":[-75.28010087738252,39.889167081829875]},
"objects":{
"temp":{
"type":"GeometryCollection",
"geometries":[{
"type":"Polygon",
"id":1,
"arcs":[[0,1,2,3,4,5,6]],
"properties":{"NAME":"Haddington"}
},{
"type":"Polygon",
"id":2,
"arcs":[[7,8,9,10,-3,11]],
"properties":{"NAME":"Carroll Park"}
}...
Thanks
So I figured it out, courtesy of: Show data on mouseover of circle
The simplest solution is to just append the names to the svg title attribute:
svg.selectAll("path")
.data(nabes.geometries)
.append("svg:title")
.attr("class", function(d) { return "path " + d.id; })
.attr("transform", function(d) { return "translate(" + path.centroid(d) + ")"; })
.attr("dy", ".35em")
.text(function(d) { return d.properties.NAME; });
Still investigating a more stylish solution to the problem (eg tipsy).
