d3.js Grouped Bar Chart: text is not showing on bars - d3.js

I am trying to add text on each bar in grouped bar chart. but it is not showing & no error is there on console.
I am using the sample code from https://bl.ocks.org/bricedev/0d95074b6d83a77dc3ad
I tried below code:

But the output is output after adding block
It is showing object object in output.
Please help.
output of code is here

You're appending to slice, which is a selection of all the bar groups, not the bars themselves. Try something like this to get started:
slice.selectAll("text")
.data(function(d) { return d.values; })
.enter().append("text")
.attr("x", function(d) { return x1(d.rate); })
.attr("y", function(d) { return y(d.value); })
.text(function(d) { return d.value })

var svg = d3.select("svg"),
margin = 200,
width = svg.attr("width") - margin,
height = svg.attr("height") - margin
var xScale = d3.scaleBand().range([0, width]).padding(0.4),
yScale = d3.scaleLinear().range([height, 0]);
var g = svg.append("g")
.attr("transform", "translate(" + 100 + "," + 100 + ")");
d3.csv("XYZ.csv", function(error, data) {
if (error) {

}
xScale.domain(data.map(function(d) { return d.year; }));
yScale.domain([0, d3.max(data, function(d) { return d.value; })]);

Below code is added for text on top of each bar:
.append("text")
.attr("x", function(d) { return xScale(d.year); })
.attr("y", function(d) { return yScale(d.value); })
.attr("text", function(d) { return d.value; })
It's impossible to append a <text> to a <rect>. Just add the texts separately:
g.selectAll(".bar-title")
.data(data)
.enter()
.append("text")
.classed('bar-title', true)
.attr('text-anchor', 'middle')
.attr("x", d => xScale(d.year) + xScale.bandwidth()/2)
.attr("y", d => yScale(d.value))
.text(d => `$${d.value}`);
... or, you can append a <g> element on enter() and then append <text> and <rect> under <g>.
const data = [
{year: 2011, value: 45},
{year: 2012, value: 47},
{year: 2013, value: 52},
{year: 2014, value: 70},
{year: 2015, value: 75},
{year: 2016, value: 78}
];
var svg = d3.select("svg"),
margin = 200,
width = svg.attr("width") - margin,
height = svg.attr("height") - margin
var xScale = d3.scaleBand().range([0, width]).padding(0.4),
yScale = d3.scaleLinear().range([height, 0]);
var g = svg.append("g")
.attr("transform", "translate(" + 100 + "," + 100 + ")");
xScale.domain(data.map(function(d) { return d.year; }));
yScale.domain([0, d3.max(data, function(d) { return d.value; })]);
g.append("g")
.attr("transform", "translate(0," + height + ")")
.call(d3.axisBottom(xScale));
g.append("g")
.call(d3.axisLeft(yScale).tickFormat(function(d){
return "$" + d;
}).ticks(10));
g.selectAll(".bar")
.data(data)

The final result should be something like this:
Your code is a good starting point, but you haven't drawn any of the columns, points or text. Here's one way to do it:
var colAndPointAndText =
svg.selectAll(".cPT")
.data(data)
.enter().append("g")
.attr("class", "cPT");
colAndPointAndText.append("rect")
.attr("x", function(d) {
return xScale(d.dayStr);
})
.attr("width", xScale.rangeBand())
.attr("y", function(d) {
return yScale(d.Ratio);
})
.attr("height", function(d) {
return height - yScale(d.Ratio);
})
.style("fill", "black");
colAndPointAndText.append("circle")
.attr("cx", function(d) {
return xScale(d.dayStr);
})
.attr("cy", function(d) {
return yScale(d.Ratio);

You have to bind the click listener to the bars (rectangles) instead of svg.

Transitions in D3 Axis

I'm trying to create a grouped bar chart that can include transitions. I referenced Mike Bostock's grouped bar chart example and have the bar chart transition working but can't get the axis to transition as well. What I'm referring to in this example is the state labels.
I tried following another example posted but I'm baffled as to why I can get it to work. For my example code the transition occurs on click of the SVG

I'm a dummy and figured it out.
Calling the .domain method on an array of objects is useless. I forgot to map the object array to get the value of the states
x0.domain(data_update.map(function(d) { return d.State; }))
