Add/Create new child node in d3js tree - d3.js

Im using the below code to create a node. But while adding a new node the whole tree is refreshing. I need to refresh the node which is added newly.
if (parentNode._children != null) {
parentNode.children = parentNode._children;
parentNode._children = null;
}
if (parentNode.children == null) { parentNode.children = []; }
parentNode.data.children.push({ 'name': 'title', 'children': [], '_children': null });
scope.root = d3.hierarchy(scope.data, function (datachild: any) {
return datachild.children;
});
scope.root.x0 = parentNode.x0;
scope.root.y0 = parentNode.y0;
update(scope.root);

I managed to update depth of the each if it has a parent.
if (parentNode._children != null) {
parentNode.children = parentNode._children;
parentNode._children = null;
}
if (parentNode.children == null) {
parentNode.children = [];
}
const nodeData = {
'name': 'title',
'children': [],
'_children': null,
'depth': 0
};
const newNode = d3.hierarchy(nodeData);
newNode.parent = parentNode;
parentNode.children.push(newNode);
parentNode.data.children.push(nodeData);
scope.inEditMode = true;
update(parentNode, true);
function update(source, addNewNode) {
// Assigns the x and y position for the nodes
const treeData = scope.tree(scope.root);
// Compute the new tree layout.
const nodes = treeData.descendants(),
links = treeData.descendants().slice(1);
// Normalize for fixed-depth.
nodes.forEach(function (d: any, i: any) {
if (addNewNode && d.parent) {
// Here you can update.
d.depth = d.parent.depth + 1;
}
d.y = d.depth * 280;
});
}

Drag&Drop element into canvas from HTML

I've got a very trivial task to drag&drop the element from a gallery into the Three.js canvas.
Nothing seems tricky until I face the problem that when I drag the item and add it to the scene I cannot update the item's coordinates until I finish the drag&drop event

Image gets rotated 90 degrees when taking portrait photo

When I'm taking an photo with my Windows Phone the landscape mode, it's perfect. The problem occurs when I'm taking a photo in portrait mode.
The photo gets rotated 90 degrees. It even occurs in the simulator as shown below.
Now this doesn't occur on Android or iOS so I assume this is because Windows is using the CameraProxy.js instead of/from cordova-plugin-camera.
My entire CameraProxy.js (Giant file, does contain 'rotate' stuff but method names are only about videos)

Does anyone know how I can keep my image rotation in Windows?
In your CameraProxy.js make changes in orientationToRotation function line number 569.
case Windows.Devices.Sensors.SimpleOrientation.notRotated:
if (cameraDirection == 0) {
return Windows.Media.Capture.VideoRotation.clockwise90Degrees;
}
else {
return Windows.Media.Capture.VideoRotation.clockwise270Degrees;
}

Performance issue when zooming (Leaflet 0.7.3)

I'm facing a performance problem with Leaflet (version 0.7.3). I'm working with an OSM map that I use to display a bunch of CircleMarkers linked by decorated Polylines (with arrow pattern every 25px). Loading take a little time but the main problem is that when I zoom the map I start facing severe lag (from the zoom level 16) and, beyond a certain limit (say 18 most of the time), browser just freeze and eventually crash (tested with chrome and firefox). I tried with a bunch of 1,000 linked markers, then I dropped to a set of around 100, but still the same concern... Of course, with 10 markers or less I don't have any problem.
Did you already face a similar trouble? How can I optimize Leaflet performances so that I can use an accurate zoom (beyond level 16) with more than 100 linked CircleMarkers ? I also wonder why performances are dropping so badly when zooming, while marker amount stay the same...
Thank you in advance for your answers,
Lenalys.
Cannot get the PolylineDecorator plugin to work on jsfiddle.
But here is the code that generate markers :

layer2 = L.tileLayer(

Have you gauged performance in canvas mode?
Use L_PREFER_CANVAS = true before initializing your leaflet map container.Might be able to help you possibly.

Update multiple tags rowchart in dc.js

I am looking for how to create a rowchart in dc.js to show and filter items with multiple tags. I've summed up a few answers given on stack overflow, and now have a working code.
var data = [
{id:1, tags: [1,2,3]},
{id:2, tags: [3]},
{id:3, tags: [1]},
{id:4, tags: [2,3]},
{id:5, tags: [3]},
{id:6, tags: [1,2,3]},
{id:7, tags: [1,2]}];
var content=crossfilter(data);
var idDimension = content.dimension(function (d) { return d.id; });
var grid = dc.dataTable("#idgrid");
grid
.dimension(idDimension)
.group(function(d){ return "ITEMS" })
.columns([
function(d){return d.id+" : "; },
function(d){return d.tags;},
])
function reduceAdd(p, v) {
v.tags.forEach (function(val, idx) {
p[val] = (p[val] || 0) + 1; //increment counts
});
return p;
}
function reduceRemove(p, v) {
v.tags.forEach (function(val, idx) {
p[val] = (p[val] || 0) - 1; //decrement counts
});
return p;
}
function reduceInitial() {
return {};
}
var tags = content.dimension(function (d) { return d.tags });
var groupall = tags.groupAll();
var tagsGroup = groupall.reduce(reduceAdd, reduceRemove, reduceInitial).value();
tagsGroup.all = function() {
var newObject = [];
for (var key in this) {
if (this.hasOwnProperty(key) && key != "") {
newObject.push({
key: key,
value: this[key]
});
}
}
return newObject;
}
var tagsChart = dc.rowChart("#idtags")
tagsChart
.width(400)
.height(200)
.renderLabel(true)
.labelOffsetY(10)
.gap(2)
.group(tagsGroup)
.dimension(tags)
.elasticX(true)
.transitionDuration(1000)
.colors(d3.scale.category10())
.label(function (d) { return d.key })
.filterHandler (function (dimension, filters) {
var fm = filters.map(Number)
dimension.filter(null);
if (fm.length === 0)
dimension.filter(null);
else
dimension.filterFunction(function (d) {
for (var i=0; i < fm.length; i++) {
if (d.indexOf(fm[i]) <0) return false;
}
return true;
});
return filters;
}
)
.xAxis().ticks(5);
It can be seen on http://jsfiddle.net/ewm76uru/24/
Nevertheless, the rowchart is not updated when I filter by one tag. For example, on jsfiddle, if you select tag '1', it filters items 1,3,6 and 7. Fine. But the rowchart is not updated... I Should have tag '3' count lowered to 2 for example.
Is there a way to have the rowchart tags counts updated each time I filter by tags ?
Thanks.
After a long struggle, I think I have finally gathered a working solution.
As said on crossfilter documentation : "a grouping intersects the crossfilter's current filters, except for the associated dimension's filter"
So, the tags dimension is not filtered when tag selection is modified, and there is no flag or function to force this reset. Nevertheless, there is a workaround (given here : https://github.com/square/crossfilter/issues/146).
The idea is to duplicate the 'tags' dimension, and to use it as the filtered dimension :
var tags = content.dimension(function (d) { return d.tags });
// duplicate the dimension
var tags2 = content.dimension(function (d) { return d.tags });
var groupall = tags.groupAll();
...
tagsChart
.group(tagsGroup)
.dimension(tags2) // and use this duplicated dimension
as it can been seen here :
http://jsfiddle.net/ewm76uru/30/
I hope this will help.
