I am trying to put together an interactive bar chart in cshtml.
The good news is it works on every browser except for Firefox.
That being said I'd very much like to know why it is failing on Firefox when it even works on Internet Explorer.. I mean come on, the internet doesn't even work on Internet Explorer.
I have added in what I believe to be the relevant patch of code here:
function buildVisualization(dataSet) {
var barWidth = (chartWidth / dataSet.Items.length - 1) - 1;
var bars = svg.selectAll("rect")
.data(dataSet.Items);
// Build bars for each item
// Example "rect" element: <rect x="200" y="400" width="300" height="100" style="" class="" />
bars.enter()
.append("rect")
.attr("x", function (item, i) { return xScale(new Date(item.DateAsked)) } )
.attr("y", function (item, i) { return chartHeight - yScale(item.Rate)})
.attr("width", function (item) { return barWidth})
.attr("height", function (item) { return yScale(item.Rate)})
.attr("fill", "teal");
bars.exit().remove();
bars.transition()
.attr("x", function (item, i) { return xScale(new Date(item.DateAsked))} )
.attr("y", function (item, i) { return chartHeight - yScale(item.Rate)})
.attr("width", function (item) { return barWidth})
.attr("height", function (item) { return yScale(item.Rate)})
.attr("fill", "teal");
}
That being said I can provide any information required if requested.
I should point out that when run the chart itself is put into the right place however the bars (an important bit of a bar chart) are all pushed off to the left and stacked on top of each other though they do change height when different options are selected so it seems to be something wrong with the positioning rather than with how they are created. Any advice would be quite welcome.

Perhaps the reason of your problem is that in Chrome
>> new Date("5-1-2008")
Thu May 01 2008 ...
while in Firefox:
>> new Date("5-1-2008")
Invalid Date
(this is relevant to lines, where you construct xScale)
I am drawing four network graphs of the same data but using different properties to color the node. Currently, I am able to generate all 4 networks and for each network I am able to double click a node to see the connected nodes of the network. My question is how do I extend this functionality so that if I click a node on any of the graph networks, the other 3 also show me the node I clicked and the connected nodes therein.
This question asked previously Mouseover event on two charts at the same time d3.js does a similar thing for pie charts but I am not sure how I can adapt it to my code.

Glad you came back with the data and the HTML. It makes it easier to debug and come up with a solution.
I just changed a couple of lines of code in the connectedNodes function:
Instead of node.style("opacity", function(o) {...}), I replaced it with:
d3.select('#Perovskite_Network').selectAll('.nodes').selectAll('circle').style("opacity", function(o) {
return neighboring(d, o) | neighboring(o, d) ? 1 : 0.15;
});
This would select all circles from all the the SVGs. Let me know if that doesn't help or if you need any improvements.

And a fiddle link: https://jsfiddle.net/shashank2104/bj76ckh4/4/
I have a few suggestions though:
The file is being fetched for every drawNetworkFunction call which slows down the rendering of the page.
Along with fetching of the file, the object linkedByIndex is created in every call which is independent of the descriptor or chartId.
Suggestion: Move the above steps in a single function and pass the linkedByIndex and graph (data) to the drawNetworkFunction and then the rest. Hope this helps.
I'm trying to grasp the D3 basics. I understand that it's crucial to get the binding right.
So I did a simple web page with update, enter and exit operations. Every time the data changes (modified, added, removed) I call a function where the data is bound to svg-objects in the update, enter and exit ways.
I wonder if my approach is a good one?
<html>
<head>
<style>
.drawarea { border-style: solid; }
</style>
<script src="https://d3js.org/d3.v4.min.js"></script>
<script>
var data, drawArea;
function init(){
data = [{"px" : 25, "py" : 25, "s" : 5}, {"px" : 25, "py" : 50, "s" : 5}, {"px" : 25, "py" : 75, "s" : 10} ];
drawArea = d3.select("#drawareadiv").append("svg:svg")
.attr("class", "drawarea")
.attr("width", 500)
.attr("height", 250);
draw();
}
function draw(){
var domRects = drawArea.selectAll("rect");
// update
domRects
.data(data)
.attr("x", function(d) { return d.px; })
.attr("y", function(d) { return d.py; })
.attr("width", function(d) { return d.s; })
.attr("height", function(d) { return d.s; });
// enter
domRects
.data(data)
.enter()
.append("svg:rect")
.attr("x", function(d) { return d.px; })
.attr("y", function(d) { return d.py; })
.attr("width", function(d) { return d.s; })
.attr("height", function(d) { return d.s; });
// exit
domRects
.data(data)
.exit()
.remove();
}
function updateDataAndBinding(){
for(i=0; i<data.length; i++)
data[i].px += 10;
draw();
}
function enterDataAndBinding(){
var px = 25;
var py = 25 * (data.length+1);
var s = Math.floor(data.length/2)*5+5;
data.push({"px" : px, "py" : py, "s" : s});
draw();
}
function exitDataAndBinding(){
data.splice(data.length-1, 1);
draw();
}
</script>
</head>
<body onload="init()">
<div id="drawareadiv"></div>
<button onclick="updateDataAndBinding()">updateDataAndBinding</button>
<button onclick="enterDataAndBinding()">enterDataAndBinding</button>
<button onclick="exitDataAndBinding()">exitDataAndBinding</button>
</body>
</html>
I'd suggest two things:
Don't bind the data again and again. Do this just one time:
var domRects = drawArea.selectAll("rect").data(data);
As this is D3 v4.x, use merge to deal with the "enter" and "update" selections together:
// enter + update
domRects.enter()
.append("svg:rect")
.attr("x", function(d) { return d.px; })
.attr("y", function(d) { return d.py; })
.attr("width", function(d) { return d.s; })
.attr("height", function(d) { return d.s; })
.merge(domRects)
.attr("x", function(d) { return d.px; })
.attr("y", function(d) { return d.py; })
.attr("width", function(d) { return d.s; })
.attr("height", function(d) { return d.s; });
Here is the demo (click "run code snippet"):
<style>
.drawarea { border-style: solid; }

Other than that, your approach seems to be a good (and standard) one.
Puzzling problem:
My d3 chart, which has a day selector (right arrow) works in a stand-alone file. By "works" I mean when you click on the right arrow it advances through the data array and the chart bars update.
However, inside a jquery mobile multipage document, it won't work in Firefox. In jqm multipage it does work in Chrome (linux and windows) and IE.
Briefly, you click on the "chart page," then click on the right arrow to view the data for each day.
Don't worry about the arrow code, I have to fix it. What worries me is that this doesn't work in Firefox.
Here is the fiddle. Try it in those browsers.

This is bizarre. I have researched this extensively, and cannot find anything that relates to it.
Has anybody else encountered this? If so, are there any ideas how to fix it?
I have two graphs(rectangles with text the other circles with text) to be displayed but instead of displaying one below the other,I want to display side by side i.e 2 charts displaying horizontally(one at the left of div and the other at right of div). I created 2 svg's and added the charts in to that. However when ever i change the top or bottom margin it is not working.
My code goes like:

You need to use CSS for this. It's easier if you have two containers:
CSS:
.container {
float: left;
}
HTML:
<div class="container" id="chart1">
</div>
<div class="container" id="chart2">
</div>
Then use #chart1 and #chart2 in your code.
