I'm having a bizarre d3 issue wherein my y-axis transition results in the axis switching sides. Besides that, I am happy with how the transition looks. A gif that demonstrates the issue is available at https://i.imgflip.com/g4kdc.gif. I have followed a few examples including http://bl.ocks.org/mbostock/4323929, but can't seem to figure out the issue.

In Bellow code I am trying to use separate charts (i.e. Bar and line chart) and getting Error: attribute d: Expected number, "MNaN,116LNaN,117L…"
Tried with using different SVG elements for both charts. Give some suggestions if I am missing something.
If I commenting Bar chart code then Line chart works properly and same works with the Bar chart but both at a same time doesn't work.
<div>

</script>
and bellow is the Json data format:
[

"DayTotal": "418",
"Timestamp": "15-Mar-18"

You are supposed to use xLine, yLine in your d3 line function whereas you used the ones(x, y) that you meant for bar charts.
var valueline = d3.line()
.x(function(d) { return xLine(d.Timestamp); })
.y(function(d) { return yLine(d.DayTotal); });

The X and Y axis are scaled too. Is there something that i have missed out?

You must have a mistake elsewhere than in the code you sent. I just put it to JSFiddle and it works correctly:
var tsv = "letter frequency\n" +

"dictionary 33\n" +
"C 55\n" +

"H 10\n" +
"I 0\n" +
"J 0";

width1 = 460 //- margin.left - margin.right,
height1 = 200 //- margin.top - margin.bottom;
var formatPercent1 = d3.format("");
var x1 = d3.scale.ordinal()
.rangeRoundBands([0, width1], 0);
//.rangeRoundBands([width1, 0);
var y1 = d3.scale.linear()
.range([height1, 0]);
var xAxis1 = d3.svg.axis()
.scale(x1)
.orient("bottom");
var yAxis1 = d3.svg.axis()
.scale(y1)
.orient("left")
.tickFormat(formatPercent1);
var svg1 = d3.select("#Bar1").append("svg")
.attr("width", width1 + margin1.left + margin1.right)
.attr("height", height1 + margin1.top + margin1.bottom)
.append("g")
.attr("transform", "translate(" + margin1.left + "," + margin1.top + ")");
var data1 = d3.tsv.parse(tsv, type)
x1.domain(data1.map(function(d) { return d.letter; }));
y1.domain([0, d3.max(data1, function(d) { return d.frequency; })]);
svg1.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height1 + ")")
.call(xAxis1);
svg1.append("g")
.attr("class", "y axis")
.call(yAxis1)
.append("text")
.attr("transform", "rotate(-90)")
.attr("y", 6)
.attr("dy", ".71em")

In your snippet, you are referring to x scale as x variable, while you actually save it in x1. The same goes for y and y1 variables. That's corrected in my snippet.
Other than that, I changed the TSV loading from d3.tsv to d3.tsv.parse, but that's just skipping the AJAX fetch of the resource. I also removed the d3.tip tooltip, but again, that shouldn't change the barchart itself.
From the looks of your image, I'd guess you're not converting the frequency to Number but leave it as a String. But that's just a guess, you might want to show the actual code that's giving you trouble.
I have loaded data from a WebSocket connection into an array variable "data". I can see the 50 elements in the array and they do have the correct map elements.
The following snippet works properly: at the end the "data" elements have all rows transformed:
data.forEach(function (d) {
d[date] = parseDate(d[date]);
d[close] = +d[close];
});
Now, how to apply this data array to the internal d3 "values" so that the subsequent d3 dom manipulations use that data? In the next snippet I have made the attempt based on the examples / blogs I had seen:
var svg = d3.select("body").selectAll("svg")
.append("svg")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom)
/* The following is NOT the correct place/way to do it.. need help here! */
.data(data)
.enter()
.append("g")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")")
UPDATE Well I just tried moving those two data(data) and .enter() lines around - now placing them right after the selectAll().
var svg = d3.select("body").selectAll("svg")
.data(data)
.enter()
.append("svg")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom)
.append("g")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")")
The results? Well we do have data now ! Maybe too much of a good thing?
EDIT Here is the entire function
function updateD3(data) {
var WIDTH = 1800, HEIGHT = 800;

By biding your data to svg elements, you are creating as many svg elements as you have data items. I suspect that is not what you want. I created this FIDDLE exemplifying what you are doing but also showing how to bind the data to a single g.
Part of fiddle with data under a single g:
var data = [10,20,30];
var svg = d3.select("body")
.append("svg")
.attr("class","oneSvg")
.attr("width", 100)
.attr("height",100)
.append("g")
.attr("transform", "translate(0,0)");
circles = svg.selectAll("circle")
.data(data);
circles
.enter()
.append("circle")
.attr("cx",function (d) {return d;})
.attr("cy",20)
.attr("r",5)
.style("fill","blue");
I have implemented the Drawing Focus + Context via Brushing diagram to display the chi-square results, but the drawing of the results in d3 are strange (check image below at 7 AM).
