I have trouble to add paths to a g element created by the nodes with selectAll:
// define the nodes
var node = svg.selectAll(".node").data(force.nodes()).enter()
.append("g").attr("id", function(d) {
return d.id;
}).attr("class", "node").style("fill", function(d) {
return color(d.group);
}).call(force.drag);
// add the nodes
...
// add the links and the arrows
var path = node.selectAll("g").data(force.links(), function(d) {
return d.id
}).append("path")
// .attr("class", function(d) { return "link " + d.type; })
.attr("class", "link").attr("marker-end", "url(#end)");
The input data looks like this:
{
"nodes": [
{
"id": 0,
"name": "N1",
"group": 4
},
{
"id": 1,
"name": "N2",
"group": 1
},
{
"id": 2,
"name": "N3",
"group": 1
}
],
"links": [
{
"id": 0,
"source": 0,
"target": 1
},
{
"id": 0,
"source": 0,
"target": 2
}
]
}
I'm trying to modify this example
My goal is that a node has a mouse over (.node:hover) including all the out-going links. With my simple data it would look like that node N1 would have a mouse over including the two links.
Thanks for your help!

I solved my issue with mouseover and mouseout:

I have the following code which draws a very simple tree. On clicking any node I'm calling the update function with new data to add a new child at the bottom of the tree.
The new node is added but the sibling node does not update it's position.
If I log out nodes:
var nodes = root.descendants();
console.log(nodes);
I can see that the position x,y has been correctly updated but I get an overlapping effect where the previous node has not moved position.
What Am I doing wrong here:

In a D3 data binding (d3.select(s).data(d)), we should be prepared to do 3 things:
enter, which adds a geom for each element in our data that's not yet in the selected DOM,
transition, which changes each selected element in the DOM using the new data, and
exit, which removes elements from the DOM if we have less data than elements in the selected DOM.
In your case, you just need to update your update() function to perform each of these three actions:

Tried like above, but cannot figure out how to do it properly. I messed up and bars does not end inside the graph somehow. The x axis domain is all messed up and also the width of the rects. It works fine if i take another scale. But in time-scale i cannot make it to work.
What i am doing wrong?
Instead of passing the difference of the values to the scale...
scale(a - b)
...pass each value to the scale and subtract them:
scale(a) - scale(b).
In your case:
return xScale(Math.abs(d.toHours)) - xScale(Math.abs(d.fromHours));
Here is the code with that change:
$(document).ready(function() {
render_chart();

I have already created a force layout with images as nodes and mouse over text.
However, now I am trying to add the ability to search for a specific node using a text box and a search button. When a user searches for text I would like to select the matching node and its connections. The matched node and connections would change color. My code is below, but my search function is not working as intended. How do I change this code to get the desired behavior?

</script>
I'm not quite sure what you intend do happen when the user clicks search. Your search function tries to select "#c" + userInput.value, but I can't see anything on the page with that ID. If your data has a name field that you want it to be searchable on then you could set the id of each node to that name with the following:
var node = svg.selectAll(".node")
.data(nodes)
.enter().append("g")
.attr("id", d => "c" + d.name) // setting ID here
.attr("class", "node")
.call(force.drag);
This would allow your search function to get a reference to the node, but currently it is just returning it, and the calling function isn't going to do anything with that reference, if you want to highlight that that node as been selected you should put some code in here to do that, e.g:
function search() {
var userInput = document.getElementById("targetNode");
var theNode = d3.select("#c"+userInput.value);
theNode.style("color", "red");
}
I have a parallel coordinates visualization and I've added a table below that represents all the data in the visualization.
I want to filter the table based on the selection of the parallel coordinates visualization. So, just showing the data highlighted in the parallel coordinates visualization.
Any ideas on how to do that?
I've tried in the brush section to highlight the cells in the table in red adding a style in for the tags, but it doesn't seem to work. See code below:
// Add and store a brush for each axis.
g.append("g")
.attr("class", "brush")
.each(function(d) {
d3.select(this).call(y[d].brush = d3.svg.brush().y(y[d]).on("brushstart", brushstart).on("brush", brush));
d3.selectAll("td").style('bgcolor', 'red');
})
.selectAll("rect")
.attr("x", -8)
.attr("width", 16);
I've tried to add the highlight of the cells in the brush function. Here I achieve for all the cells to turn red, but I don't know how to highlight only the ones selected in the selection.
function brush() {
var actives = dimensions.filter(function(p) {
return !y[p].brush.empty();
}),
extents = actives.map(function(p) {
return y[p].brush.extent();
});
foreground.style("display", function(d) {
return actives.every(function(p, i) {
return extents[i][0] <= d[p] && d[p] <= extents[i][1];
}) ? null : "none";
});
d3.selectAll("td").style('background-color', 'red');
}

I've added also the code in JSFiddle but it doesn't display anything. I'm not sure what I'm doing wrong. I'm not familiar with JSFiddle, so I might be doing something wrong.
I've tried also to use divgrid (DivGrid) and with the following code I can see how when I attempt to brush the table gets updated. The problem is that it doesn't get updated with the data I need. I just have it to show 5 records.
<script src="divgrid.js"></script>
...
// Handles a brush event, toggling the display of foreground lines.
function brush() {
var actives = dimensions.filter(function(p) {
return !y[p].brush.empty();
}),
extents = actives.map(function(p) {
return y[p].brush.extent();
});
foreground.style("display", function(d) {
return actives.every(function(p, i) {
return extents[i][0] <= d[p] && d[p] <= extents[i][1];
}) ? null : "none";
});
//d3.selectAll("td").style('background-color', 'red');
var grid = d3.divgrid();
d3.select('body')
.datum(notas.slice(0,5))
.call(grid);
}
The problems I have (I think) is that (1) the update of the table is not really in the right place as it is only updating when starting to brush, not when brushing over the lines and (2) I need to find a way to pickup the data from the lines that are selected. I've added to code in github as a reference (GitHub)
Any ideas?
Thanks
