dc.js - Rendering two objects (one chart - renders, one shape - doesn't) together in one group?

I have two elements I need to render and a context of the big picture I am trying to achieve (a complete dashboard).
One is a chart that renders fine.
$scope.riskChart = new dc.pieChart('#risk-chart');
$scope.riskChart
.width(width)
.height(height)
.radius(Math.round(height/2.0))
.innerRadius(Math.round(height/4.0))
.dimension($scope.quarter)
.group($scope.quarterGroup)
.transitionDuration(250);
The other is a triangle, to be used for a more complex shape
$scope.openChart = d3.select("#risk-chart svg g")
.enter()
.attr("width", 55)
.attr("height", 55)
.append('path')
.attr("d", d3.symbol('triangle-up'))
.attr("transform", function(d) { return "translate(" + 100 + "," + 100 + ")"; })
.style("fill", fill);
On invocation of render functions, the dc.js render function is recognized and the chart is seen, but the d3.js render() function is not recognized.
How do I add this shape to my dc.js canvas (an svg element).
$scope.riskChart.render(); <--------------Works!
$scope.openChart.render(); <--------------Doesn't work (d3.js)!
How do I make this work?
EDIT:
I modified dc.js to include my custom chart, it is a work in progress.
dc.starChart = function(parent, fill) {
var _chart = {};
var _count = null, _category = null;
var _width, _height;
var _root = null, _svg = null, _g = null;
var _region;
var _minHeight = 20;
var _dispatch = d3.dispatch('jump');
_chart.count = function(count) {
if(!arguments.length)
return _count;
_count = count;
return _chart;
};
_chart.category = function(category) {
if(!arguments.length)
return _category
_category = category;
return _chart;
};
function count() {
return _count;
}
function category() {
return _category;
}
function y(height) {
return isNaN(height) ? 3 : _y(0) - _y(height);
}
_chart.redraw = function(fill) {
var color = fill;
var triangle = d3.symbol('triangle-up');
this._g.attr("width", 55)
.attr("height", 55)
.append('path')
.attr("d", triangle)
.attr("transform", function(d) { return "translate(" + 25 + "," + 25 + ")"; })
.style("fill", fill);
return _chart;
};
_chart.render = function() {
_g = _svg
.append('g');
_svg.on('click', function() {
if(_x)
_dispatch.jump(_x.invert(d3.mouse(this)[0]));
});
if (_root.select('svg'))
_chart.redraw();
else{
resetSvg();
generateSvg();
}
return _chart;
};
_chart.on = function(event, callback) {
_dispatch.on(event, callback);
return _chart;
};
_chart.width = function(w) {
if(!arguments.length)
return this._width;
this._width = w;
return _chart;
};
_chart.height = function(h) {
if(!arguments.length)
return this._height;
this._height = h;
return _chart;
};
_chart.select = function(s) {
return this._root.select(s);
};
_chart.selectAll = function(s) {
return this._root.selectAll(s);
};
function resetSvg() {
if (_root.select('svg'))
_chart.select('svg').remove();
generateSvg();
}
function generateSvg() {
this._svg = _root.append('svg')
.attr({width: _chart.width(),
height: _chart.height()});
}
_root = d3.select(parent);
return _chart;
}

I think I confused matters by talking about how to create a new chart, when really you just want to add a symbol to an existing chart.
In order to add things to an existing chart, the easiest thing to do is put an event handler on its pretransition or renderlet event. The pretransition event fires immediately once a chart is rendered or redrawn; the renderlet event fires after its animated transitions are complete.
Adapting your code to D3v4/5 and sticking it in a pretransition handler might look like this:
yearRingChart.on('pretransition', chart => {
let tri = chart.select('svg g') // 1
.selectAll('path.triangle') // 2
.data([0]); // 1
tri = tri.enter()
.append('path')
.attr('class', 'triangle')
.merge(tri);
tri
.attr("d", d3.symbol().type(d3.symbolTriangle).size(200))
.style("fill", 'darkgreen'); // 5
})
Some notes:
Use chart.select to select items within the chart. It's no different from using D3 directly, but it's a little safer. We select the containing <g> here, which is where we want to add the triangle.
Whether or not the triangle is already there, select it.
.data([0]) is a trick to add an element once, only if it doesn't exist - any array of size 1 will do
If there is no triangle, append one and merge it into the selection. Now tri will contain exactly one old or new triangle.
Define any attributes on the triangle, here using d3.symbol to define a triangle of area 200.
Example fiddle.

Because the triangle is not bound to any data array, .enter() should not be called.
Try this way:
$scope.openChart = d3.select("#risk-chart svg g")
.attr("width", 55)
.attr("height", 55)
.append('path')
.attr("d", d3.symbol('triangle-up'))
.attr("transform", function(d) { return "translate(" + 100 + "," + 100 + ")"; })
.style("fill", fill);

D3js V4 - How to zoom scatter plot matrix chart

I'm a freshman using js and d3. How can I zoom a scatter plot matrix chart?
What I did,
I used svg to show the scatter plot matrix, following the example https://bl.ocks.org/Fil/6d9de24b31cb870fed2e6178a120b17d
Since the performance was too bad when the records over 10 thousands and the matrix size is 10*10, I changed the point draw with canvas
Axes are using svg and the dots are drew by canvas
Even if it spends some time to draw the chart with canvas, the page will not hang and oom when running 10*10 matrix over 10 thousands records
I'm not sure it's a formal way to do this.
On the other hand, I want to zoom this chart but I have no idea how can I do this.
From my understanding,
The axes splits into several parts according to the number of matrix, such as 10, including x-axis and y-axis
If I want to rescale each matrix cell, such as the cell on row 0 and column 0, how can I do this? I just tired with d3.event.transform.rescaleX/rescaleY to rescale the axes, this seems to work but how can I do on the canvas, how can I get the valid dots to redraw?
On the other hand, if I only want to zoom the whole chart not the single cell(That means, if I click on cell(0,0), this cell will zoom until it fill the whole chart and other cells will not be seen), how can I do this? I used modal to show the scaled large svg by viewBox="0 0 ' + width * scalar + ' ' + height, is there any other way to show image in large format?

D3 v4 Animation: How to loop over multiple circles over multiple paths?

Inspired by https://www.nytimes.com/interactive/2018/03/19/upshot/race-class-white-and-black-men.html
I am trying to create a animation that will have markers move from one point to multiple levels in another point in the y axis. Thanks to detailed pages by Amelia and Mike Bostock in both bl.ocks.org and stackoverflow. I have got so far to get the circles and animate it. But, I am not able to make each marker loop over by the pathlevel and do the transition
Pathlevel, here, indicates whether they are high, middle or low (1,2,3).
The entire code in using d3.v4 has been pasted below. what I am missing?
Thanks for your help.

javascript x3dom insert via ajax

You cannot add the whole x3d element and a scene dynamically per se since x3dom is initialized with an window.onload event. This should be part of your HTML document beforehand. Then you can add the elements (views, shapes etc) to the scene.
But I heard sometime ago something about a reload function (https://github.com/x3dom/x3dom/blob/1.7.1/src/Main.js#L327) in the mailing list, sadly this is not well documented:
/** Initializes an <x3d> root element that was added after document load. */
x3dom.reload = function() {
onload();
};
This should be doing what you want.

Converting static code into reusable D3.js pie animation

I'm trying to rework a pen (http://codepen.io/anon/pen/JgyCz) by Travis Palmer so that I can use it on multiple elements. We are trying to place several <div class="donut" data-donut="x">'s on a page.
So it would look similar to the html below:
////// HTML
<div class="donut" data-donut="22"></div>
<div class="donut" data-donut="48"></div>
<div class="donut" data-donut="75></div>
The D3.js / jQuery example I'm trying to convert to a reusable compunent is below. (To see full working example go to this link - http://codepen.io/anon/pen/JgyCz)
////// D3.js
var duration = 500,
transition = 200;
drawDonutChart(
'.donut',
$('.donut').data('donut'),
290,
290,
".35em"
);
function drawDonutChart(element, percent, width, height, text_y) {
width = typeof width !== 'undefined' ? width : 290;
height = typeof height !== 'undefined' ? height : 290;
text_y = typeof text_y !== 'undefined' ? text_y : "-.10em";
var dataset = {
lower: calcPercent(0),
upper: calcPercent(percent)
},
radius = Math.min(width, height) / 2,
pie = d3.layout.pie().sort(null),
format = d3.format(".0%");
var arc = d3.svg.arc()
.innerRadius(radius - 20)
.outerRadius(radius);
var svg = d3.select(element).append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width / 2 + "," + height / 2 + ")");
var path = svg.selectAll("path")
.data(pie(dataset.lower))
.enter().append("path")
.attr("class", function(d, i) { return "color" + i })
.attr("d", arc)
.each(function(d) { this._current = d; }); // store the initial values
var text = svg.append("text")
.attr("text-anchor", "middle")
.attr("dy", text_y);
if (typeof(percent) === "string") {
text.text(percent);
}
else {
var progress = 0;
var timeout = setTimeout(function () {
clearTimeout(timeout);
path = path.data(pie(dataset.upper)); // update the data
path.transition().duration(duration).attrTween("d", function (a) {
// Store the displayed angles in _current.
// Then, interpolate from _current to the new angles.
// During the transition, _current is updated in-place by d3.interpolate.
var i = d3.interpolate(this._current, a);
var i2 = d3.interpolate(progress, percent)
this._current = i(0);
return function(t) {
text.text( format(i2(t) / 100) );
return arc(i(t));
};
}); // redraw the arcs
}, 200);
}
};
function calcPercent(percent) {
return [percent, 100-percent];
};

The best way to do this is to use angular directives. An angular directive basically wraps html inside a custom tag and let's you stamp the directive over and over across multiple pages or multiple times a page. See this video: http://www.youtube.com/watch?v=aqHBLS_6gF8
There is also a library that is out called nvd3.js that contains prebuilt angular directives that can be re-used: http://nvd3.org/
Hope this helps.

ok, I figured it out. I feel a bit dumb in hindsight, but what can I say, I'm a js n00b. All you have to do is make a few more call to the drawDonutChart() method. In short:
drawDonutChart(
'#donut1',
$('#donut1').data('donut'),
220,
220,
".35em"
);
drawDonutChart(
'#donut2',
$('#donut2').data('donut'),
120,
120,
".35em"
);
drawDonutChart(
'#donut3',
$('#donut3').data('donut'),
150,
150,
".2em"
);
