Error while merging 'double click' code with old d3 'rebind' substitute - d3.js

I try to revive double click event which was presented in previous versions of D3 for 'node.on' method. I need to use it with d3.forceSimulation.
The substitute snippet for double click event which I found works fine on old version of d3. It uses also the old d3.rebind method which is removed from the current d3 and which also has the substitute.
I tried to merge these two snippets but it failed with error 'Cannot read property 'apply' of undefined'.
Here's the merged code:
<div id='map'></div>
<script>
function clickcancel() {
// Copies a variable number of methods from source to target.
d3.rebind = function(target, source) {
var i = 1, n = arguments.length, method;
while (++i < n) target[method = arguments[i]] = d3_rebind(target, source, source[method]);
return target;
};
// Method is assumed to be a standard D3 getter-setter:
// If passed with no arguments, gets the value.
// If passed with arguments, sets the value and returns the target.
function d3_rebind(target, source, method) {
return function() {
var value = method.apply(source, arguments);
return value === source ? target : value;
};
}
// we want to a distinguish single/double click
// details http://bl.ocks.org/couchand/6394506
var event = d3.dispatch('click', 'dblclick');
function cc(selection) {
var down, tolerance = 5, last, wait = null, args;
// euclidean distance
function dist(a, b) {
return Math.sqrt(Math.pow(a[0] - b[0], 2), Math.pow(a[1] - b[1], 2));
}
selection.on('mousedown', function() {
down = d3.mouse(document.body);
last = +new Date();
args = arguments;
});
selection.on('mouseup', function() {
if (dist(down, d3.mouse(document.body)) > tolerance) {
return;
} else {
if (wait) {
window.clearTimeout(wait);
wait = null;
event.dblclick.apply(this, args);
} else {
wait = window.setTimeout((function() {
return function() {
event.click.apply(this, args);
wait = null;
};
})(), 300);
}
}
});
};
return d3.rebind(cc, event, 'on');
}
var cc = clickcancel();
d3.select('#map').call(cc);
cc.on('click', function(d, index) {
d3.select('#map').text(d3.select('#map').text() + 'click, ');
});
cc.on('dblclick', function(d, index) {
d3.select('#map').text(d3.select('#map').text() + 'dblclick, ');
});

Simpler way to get double click functionality:
//Set variables
<script type="text/javascript">
var clickDate = new Date();
var difference_ms;
//Set dragstarted functionality fired on '.call(d3.drag().on("start", dragstarted)'
function dragstarted(d) {
difference_ms = (new Date()).getTime() - clickDate.getTime();
clickDate = new Date();
if(difference_ms > 200) {
d3.select(this).classed("fixed", d.fixed = true);
if (!d3.event.active) simulation.alphaTarget(0.3).restart();
d.fx = d.x;
d.fy = d.y;
} else {
d3.select(this).classed("fixed", d.fixed = false);
if (!d3.event.active) simulation.alphaTarget(0.3).restart();
d.fx = d.x;
d.fy = d.y;
};
}
//Set dragended functionality fired on '.call(d3.drag().on("end", dragended)'
function dragended(d) {
if (!d3.event.active) simulation.alphaTarget(0);
if(difference_ms < 200) {
d.fx = null;
d.fy = null;
};
}
The way the tricky code that I stumbled upon could be revived is described here in comments of honorable nharrisanalyst. Though I still don't get why one should follow such a sophisticated path:
var cc = clickcancel();
d3.select('#map').call(cc); //#map is the element just for example
cc.on('click', function(d, index) {
d3.select('#map').text(d3.select('#map').text() + 'click, ');
});
cc.on('dblclick', function(d, index) {
d3.select('#map').text(d3.select('#map').text() + 'dblclick, ');
});
function clickcancel() {}

aspx page on Sharepoint error: Function Expected only when rendering datatable

I have been building a reporting page in sharepoint with dc and crossfilter.
Right now on my page, I have 5 pie charts that render with no problem. However, when I tried to add a dc datatable to the page to show results of the charts as they are filtered, I get a javascript error on "resultsChart.render();"
Because no errors are given when I render each of the pie charts, I assume this to mean that something is off with the datatable object, or that I cannot call render() on that object (whatever it thinks it is).
Here are the relevant pieces of my code:

Any and all help is extremely appreciated!
I figured it out. According to the dc.dataTable documentation, you cannot use a crossfilter group as the .group attribute on a datatable. Instead, you must explicitly use a function there.
So it should be
resultChart
.dimension(compdate)
.group(function(d) { return d.compdate;})
.columns([
function(d) { return d.ait},
function(d) { return d.project},
function(d) { return d.stoplight},
function(d) { return d.compdate}
])
.size(100);
Instead of
resultChart
.dimension(compdate)
.group(compDateGroup)
.columns([
function(d) { return d.ait},
function(d) { return d.project},
function(d) { return d.stoplight},
function(d) { return d.compdate}
])
.size(100);

Distinguishing click and double-click in D3 Version 4

I have seen http://bl.ocks.org/couchand/6394506 which applies to d3 Version 3, but I have discovered that d3.rebind is no longer supported in Version 4. Can someone please help as I need this functionality?
As the CHANGELOG states, rebind can be replaced by implementing a simple wrapper function.
cc.on = function() {
var value = event.on.apply(event, arguments);
return value === event ? cc : value;
};
return cc;
function clickcancel() {
var event = d3.dispatch('click', 'dblclick');
function cc(selection) {
var down,
tolerance = 5,
last,
wait = null;
// euclidean distance
function dist(a, b) {
return Math.sqrt(Math.pow(a[0] - b[0], 2), Math.pow(a[1] - b[1], 2));
}
selection.on('mousedown', function() {
down = d3.mouse(document.body);
last = +new Date();
});
selection.on('mouseup', function() {
if (dist(down, d3.mouse(document.body)) > tolerance) {
return;
} else {
if (wait) {
window.clearTimeout(wait);
wait = null;
event.call('dblclick', d3.event);
} else {
wait = window.setTimeout((function(e) {
return function() {
event.call('click', e);
wait = null;
};
})(d3.event), 300);
}
}
});
};
cc.on = function() {
var value = event.on.apply(event, arguments);
return value === event ? cc : value;
};
return cc;
}
var cc = clickcancel();
d3.select('#map').call(cc);
cc.on('click', function() {
d3.select('#map').text(d3.select('#map').text() + 'click, ');
});
cc.on('dblclick', function() {
d3.select('#map').text(d3.select('#map').text() + 'dblclick, ');
});
#map {
width: 960px;
height: 500px;
background: cyan;
}
<script src="https://d3js.org/d3.v4.min.js"></script>
<div id='map'></div>
This is simply the source from the original rebind method.

Dynamic filtering with D3

I'm quite new to D3 and coding in general. I'm trying to set up a bar chart which includes/excludes data depending on a checkbox. I have a set of product groups and countries which I want to toggle in/out of the total represented by the bar. The output should be one bar per product.
My full data set has many more products, product groups and countries so it is not viable to create a key-value pair for each potential combination of checkboxes. Instead I would like to create a function that re-evaluates the checkboxes and re-filters the data and updates the rollup when a checkbox is changed.
I'm not sure where this function should sit in my code or what it should look like... This is what I'm working with at the moment:
var data = data.filter(function(d) {
if (document.getElementById("nz_button").checked) {
return d.country == 'NZ'
}
if (document.getElementById("au_button").checked) {
return d.country == 'AU'
}
if (document.getElementById("us_button").checked) {
return d.country == 'US'
}
})
// to see how many distinct groups there are and sum volume
var products = d3.nest()
.key(function(d) {
return d.product
})
.rollup(function(leaves) {
var sum = 0;
leaves.forEach(function(d) {
sum += d.volume;
})
return sum
})
.entries(data);
Full code: http://plnkr.co/edit/qezdwMLt48RPc8KH17hS?p=preview
Maybe I should be working with selections and re-running the nest/rollup when required?
Any help appreciated. Thanks :)
You can move the full code which makes the graph in a new function like this:
function makeDataGraph(data) {//function to make the graph.
//
// FILTER
//
var data = data.filter(function(d) {
if (document.getElementById("au_button").checked) {
return d.country == 'AU'
}
if (document.getElementById("us_button").checked) {
return d.country == 'US'
}
if (document.getElementById("nz_button").checked) {
return d.country == 'NZ'
}
})
// to see how many distinct groups there are and sum volume
var products = d3.nest()
.key(function(d) {
return d.product
})
.rollup(function(leaves) {
var sum = 0;
leaves.forEach(function(d) {
sum += d.volume;
})
return sum
})
.entries(data);
// sorting on descending total
console.log(products);
products.sort(function(a, b) {
return b.values - a.values
})
var max = d3.max(products, function(d) {
return d.values;
});
var xscale = d3.scale.linear()
.domain([0, max])
.range([0, 600])
var svg = d3.select("svg");
//
// Still needs to be cleaned up \/ \/
//
var rects = svg.selectAll("rect.product")
.data(products)
rects.exit().remove();
rects.enter().append("rect").classed("product", true)
rects.attr({
x: 200,
y: function(d, i) {
return 100 + i * 50
},
width: function(d, i) {
return xscale(d.values)
},
height: 50
}).on("click", function(d, i) {
console.log(i, d);
})
var labels = svg.selectAll("text.label")
.data(products)
labels.exit().remove();
labels.enter().append("text").classed("label", true)
labels.attr({
x: 195,
y: function(d, i) {
return 128 + i * 50
},
"text-anchor": "end",
"alignment-baseline": "middle"
}).text(function(d) {
return d.key || "N/A"
})
var volume = svg.selectAll("text.volume")
.data(products);
volume.exit().remove();
volume.enter().append("text").classed("volume", true)
volume.attr({
x: function(d, i) {
return 205 + xscale(d.values)
},
y: function(d, i) {
return 128 + i * 50
},
"text-anchor": "start",
"alignment-baseline": "middle"
}).text(function(d) {
return d.values || "N/A"
})
}
Remember to do rects.exit().remove(); so that when the data is changed on click of the checkbox, rectangles related to old data is removed.
Now you can call this function from the click event and also afterloading the tsv like this:
d3.tsv("data.tsv", function(err, udata) {
var udata = udata.map(process);
console.log("udata", udata);
var data = udata // making new var to preserve unfiltered data
makeDataGraph(data);//call the function to make graph
function handleClick() { // event handler...
makeDataGraph(data)
}
//add listener to all check boxes.
d3.selectAll(".filter_button").on("click", handleClick);
});

show percentage in d3 pie chart

currently my pie chart in d3 shows the sum of numbers,i want percentage instead .
for eg: currently i have a pie chart for how many people submitted application who visited our site. our current pie chart shows like this : people submitted 17,000 and people didn't submitted-10,000
but i need this in percentage also. how can i get that.
please find the pie code below and let me know what changes do i need to make this work. I am new to JavaScript and D3.

A fiddle would be useful to test this against (hint hint), but I'm pretty sure you want to change this line:
.y(function (d) {
return d.value
})
to this
.y(function (d) {
return d.value/total
})
You may have to define total. Like I said, without a jsfiddle or at least some indication of the format of your data, it's hard to determine if this is actually what's wrong or how to fix it.
Note: a pie chart of relative percentages will look exactly the same as a pie chart of the original numbers. You might be able to change the label and only the label, as follows:
return '<h3>' + hueUtils.htmlEncode(key) + '</h3><p>' + y + '</p>'
to this
return '<h3>' + hueUtils.htmlEncode(key) + '</h3><p>' + (y/total) + '</p>'
Hopefully both of those should work. You will have to define total, if it isn't already defined elsewhere. If not:
var total = 0;
_data.forEach(function(d){total += d.value});
Good luck!
It would be even more helpful to include information such as the library you are using and a fully reproducible example using a gist, codepen, jsfiddle, etc. I am guessing you are using hue and more specifically growingPieChart. If my guesses are correct, then you can modify your tooltipContent function similar to #Vyross answer that posted while I was typing this.
.tooltipContent(function (key, y, e, graph) {
return '<h3>' + hueUtils.htmlEncode(key) + '</h3><p>' +
(+y) / d3.sum(
d3.select(graph.container).select('g').datum(),
function(d){return d.value}
) +
'</p>'
});

How to override a function in NVD3 library?

My goal is to override the function used by NVD3 for the content of a tooltip.
I found the function that provides this behaviour: contentGenerator.
Below here the code:
var contentGenerator = function(d) {
if (content != null) {
return content;
}
if (d == null) {
return '';
}
var table = d3.select(document.createElement("table"));
var theadEnter = table.selectAll("thead")
.data([d])
.enter().append("thead");
theadEnter.append("tr")
.append("td")
.attr("colspan",3)
.append("strong")
.classed("x-value",true)
.html(headerFormatter(d.value));
var tbodyEnter = table.selectAll("tbody")
.data([d])
.enter().append("tbody");
var trowEnter = tbodyEnter.selectAll("tr")
.data(function(p) { return p.series})
.enter()
.append("tr")
.classed("highlight", function(p) { return p.highlight});
trowEnter.append("td")
.classed("legend-color-guide",true)
.append("div")
.style("background-color", function(p) { return p.color});
trowEnter.append("td")
.classed("key",true)
.html(function(p) {return p.key});
trowEnter.append("td")
.classed("value",true)
.html(function(p,i) { return valueFormatter(p.value,i) });
trowEnter.selectAll("td").each(function(p) {
if (p.highlight) {
var opacityScale = d3.scale.linear().domain([0,1]).range(["#fff",p.color]);
var opacity = 0.6;
d3.select(this)
.style("border-bottom-color", opacityScale(opacity))
.style("border-top-color", opacityScale(opacity))
;
}
});
var html = table.node().outerHTML;
if (d.footer == undefined)
html += "<div class='footer'>" + d.footer + "</div>";
return html;
};
Now, I'd like to put inside my chart section the function to override this method.
var chart = nv.models.lineChart()
.x(function(d) { return d.x; })
.y(function(d) { return d.y; })
.useInteractiveGuideline(false)
.tooltipContent(function (key, x, y, e, graph) {
return contentGenerator
});
How Can I achieve this goal?
I wanted to customise:
1) In the header add a simple text
2) Add a footer
