D3 js grouped bar chart position - javascript

I use the tutorial from http://bost.ocks.org/mike/bar/3/. While I want to have a grouped bar chart like
(source: academyhealth.org)
.Followed the answer of my last question, i create two data sets but the y-position of the second data sets can never be set as same as the first one. Here is code snippet that set position of bar chart.
var bar = chart.selectAll("g")
.data(data_1)
.enter().append("g")
.attr("transform", function(d, i) { return "translate(" + (i * barWidth+60) + ", -100)"; });
Here is the code:
<!DOCTYPE html>
<meta charset="utf-8">
<style>
.chart rect {
fill: steelblue;
}
.chart text {
fill: white;
font: 10px sans-serif;
text-anchor: middle;
}
</style>
<svg class="chart"></svg>
<svg class="chart_1"></svg>
<script src="http://d3js.org/d3.v3.min.js"></script>
<script>
var data = [4, 5];
var width = 960,
height = 500;
var y = d3.scale.linear()
.range([height, 0])
.domain([0, d3.max(data)]);
var chart = d3.select(".chart")
.attr("width", width)
.attr("height", height);
var barWidth_ = width /data.length;
var barWidth = barWidth_/2;
var bar = chart.selectAll("g")
.data(data)
.enter().append("g")
.attr("transform", function(d, i) { return "translate(" + i * barWidth + ",0)"; });
bar.append("rect")
.attr("y", function(d) { return y(d); })
.attr("height", function(d) { return height - y(d); })
.attr("width", barWidth -200);
bar.append("text")
.attr("x", barWidth / 2)
.attr("y", function(d) { return y(d) + 3; })
.attr("dy", ".75em")
.text(function(d) { return d; });
var data_1 = [1000, 1000];
var width = 960,
height = 500;
var y = d3.scale.linear()
.range([height, 0])
.domain([0, d3.max(data_1)]);
var chart = d3.select(".chart_1")
.attr("width", width)
.attr("height", height);
var barWidth_ = width /data_1.length;
var barWidth = barWidth_/2;
var bar = chart.selectAll("g")
.data(data_1)
.enter().append("g")
.attr("transform", function(d, i) { return "translate(" + (i * barWidth+60) + ", -100)"; });
bar.append("rect")
.attr("y", function(d) { return y(d); })
.attr("height", function(d) { return height - y(d); })
.attr("width", barWidth -200);
bar.append("text")
.attr("x", barWidth / 2)
.attr("y", function(d) { return y(d) + 3; })
.attr("dy", ".75em")
.text(function(d) { return d; });

d3 v5 use nested values when scaling axis

I have the following code that nests my data based on region and date. The problem I am having is that I don't know how to define yScale to dynamically draw the axis so that the max sum from the nested data is returned (the max val of the nested data is higher than the max val in the dataset bc it is aggregated). Thus my yAxis is truncated and the chart doesn't show all the data.
In the code, if I hardcode the domain to .domain([0, 3500]) then the axis is correct, but otherwise it is not correct. I don't want to hardcode the domain. How do I reference the nested values?
EDITED to show code provided in comments, which helps but doesn't entirely fix when the script is run on the entire dataset. Please see pic at bottom.
var yScale = d3.scaleLinear()
.domain([0, d3.max(dataset, function(d) {
return parseInt(d.count,10);
})])
.range([h - padding, padding])
// var yScale = d3.scaleLinear()
// .domain([0, 3500])
// .range([h - padding, padding]) //not supposed to hard code the scale but it is not working

UPDATE :
The max value of yAxis is less than the actual max value of the nest data, so it's truncated.
You have to use your nest data inside yScale calculation rather than using the original dataset data.
Steps to achieve this:
define nest first
get the totalMax value by flatting nest twice
use totalMax to calculate the yScale value
var totalMax = Object
.entries(nest)
.reduce(function(totalMax, [key, regionValue]){
const regionMax = Object
.entries(regionValue.values)
.reduce(function(regionMax, [key,yearValue]){
return parseInt(yearValue.value,10) > regionMax ? parseInt(yearValue.value, 10) : regionMax;
}, 0)
return parseInt(regionMax, 10) > totalMax ? parseInt(regionMax, 10) : totalMax;
}, 0)
var yScale = d3.scaleLinear().domain([0, totalMax]).range([h - padding, padding])
I write a Demo base on your code :
var parseTime = d3.timeParse("%Y");
var margin = {
top: 20,
right: 20,
bottom: 30,
left: 50
},
w = 960 - margin.left - margin.right,
h = 500 - margin.top - margin.bottom;
var padding = 20;

I noticed the data type of your d.count is string so that the max won't be correct.
console.log(d3.max(['6','2245'])) // it's 6!
Try converting the value to the number before return it :
var yScale = d3.scaleLinear()
.domain([0, d3.max(dataset, function(d) {
return parseInt(d.count,10);
})])
.range([h - padding, padding])
To get max value inside nested array you can nest d3.max function in the way like"
var maxCountSum = d3.max(nest, function(d) {
return d3.max(d.values, function (f) {
return f.value
});
});
Then apply to yScale domain:
var yScale = d3.scaleLinear()
.domain([0, maxCountSum]).range([height, 0]);

Error: <rect> attribute y: Expected length, "NaN"

I am trying to follow this example here for a D3 stacked chart. I've tested it locally and it works fine.
I have adapted the code to match my csv dataset, but unfortunately I get issues with the calculation of y and height attributes:
Error: attribute y: Expected length, "NaN".
Error: attribute height: Expected length, "NaN".

Instead of
var stack = d3.stack()
.keys(["In Scope", "Out Scope"]) <-- there is no key as such
.order(d3.stackOrderDescending)
.offset(d3.stackOffsetNone);
it should have been:
var stack = d3.stack()
.keys(["in_scope", "out_scope"])

.offset(d3.stackOffsetNone);
Reason: there is no keys in your CSV "In Scope", "Out Scope"
It should have been "in_scope", "out_scope"
EDIT
For tool tip :
tooltip.select("text").text(d.data.city + ": " + (d[1] - d[0]));
should have been
tooltip.select("text").text(d.data.type + ": " + (d[1] - d[0]));
Reason: There is no data.city in your CSV.

D3.js add label to bar chart

How can I add label to a bar chart? The bar chart extends along the x-axis and I want to append the labels along the y-axis.
I read some examples and they use an external .tsv or .csv file. Can I store them in an array instead? My code is below :
var data = [7, 8, 15, 16];
var label = ["as","bs","cs","ds"];
var width = 420,
barHeight = 20;
var x = d3.scale.linear()
.domain([0, d3.max(data)])
.range([0, width]);
var chart = d3.select(".chart")
.attr("width", width)
.attr("height", barHeight * data.length);
var bar = chart.selectAll("g")
.data(data)
.enter().append("g")
.attr("transform", function(d, i) { return "translate(0," + i * barHeight + ")"; });
bar.append("rect")
.attr("width", x)
.attr("height", barHeight - 1);
bar.append("text")
.attr("x", function(d) { return x(d) - 3; })
.attr("y", barHeight / 2)
.attr("dy", ".35em")
.text(function(d) { return d; });
You can get the value of your label by the index like this :
bar.append("text")
.attr("x", function(d) { return x(d) - 3; })
.attr("y", barHeight / 2)
.attr("dy", ".35em")
.text(function(d, i) { return label[i]; });

Stacked Bar Chart to Grouped Bar Chart transition not working

I have a stacked bar chart to Grouped bar chart function with transition that works fine with one chart, but as soon as I add a second it breaks. The first chart will not transition and the second chart works fine. I think this has something to do with the transition being in a function so it only runs for the last chart made.
Any help on this would be great!?
I put together a jsFiddle for this here
My function is as follows:
function createChartDate(inputdata, chartname, inputtop, inputbottom, inputwidth, inputheight, inputleft, inputright, bargap, yaxisShift) {
var stack = d3.layout.stack(),
layers = inputdata,
m = layers[0].length, // number of samples per layer
n = layers.length, // number of layers
data = stack(d3.range(n).map(function(d) {
return layers[d];
}));
var yGroupMax = d3.max(data, function(layer) {
return d3.max(layer, function(d) {
return d.y;
});
}),
yStackMax = d3.max(data, function(layer) {
return d3.max(layer, function(d) {
return d.y0 + d.y;
});
});
var margin = {

As I said in my comment:
Since your createChartDate function wraps multiple variables (and
other functions), your charts aren't independent of each other. Only
the last one transitions because var allchart =
d3.select(chartname)..., chartname holds the value "#chart2"
Lots of ways to fix this but a quick refactor would be to have your createChartDate return the transition functions (in an object), so you can call them later (and you create a closure).

Thanks in advance
first, as we discussed here (d3 Donut chart does not render), you should position your
<div id="body1" height="30%" width="90px"></div>
above the script.
second, you are missing the # in your second svg-declaration to correctly select the div by its id, it has to be
var svg = d3.select("#body1").append("svg")
you could also think about naming the second svg differently (eg svg2) so you don't override your first svg-variable (in case you want to do something with it later).
