CallOut Function Returning Undefined - javascript

I'm building three line graphs in d3.js and I would like that when the viewer hovers over a section of the line graph, they are able to see the country, date and incidents. Currently all that is being returned is an undefined. any help would be immensely appreciated.
Here is my html:
<div id="callOut">
<div id="divCountry"></div>
<div id="divDate"></div>
<div id="divIncidents"></div>
</div>
Here are my helper functions:
function circleHover(chosen) {
if (modus == "incidents") {
d3.select("#callOut")
.style("top", "570px")
.style("left", "30px");
d3.select("#divCountry").html('Country: ' + chosen.country);
d3.select("#divDate").html('Date: ' + chosen.date);
d3.select("#divIncidents").html('Incidents: ' + chosen.incidents);
d3.select("#callOut")
.style("visibility","visible");
}
};
function showOne(d) {
var margin = {top: 80, right: 80, bottom: 80, left: 80},
width = 960 - margin.left - margin.right,
height = 500 - margin.top - margin.bottom;
var svg = d3.select("#svg").append("svg")
.attr("width", width)
.attr("height", height);
var incidentsData = svg.append("g");
incidentsData.selectAll(".incidentsData")
.data(incidentData)
.enter()
.append('incidentsData')
.attr('class', 'incidentsData');
var chosen = d;
var setOpacity = 0;
if (modus == "incidents") {
circleHover(chosen);
setOpacity = 0.1;
incidentsData.selectAll(".incidentsData")
.filter(function (d) { return eval("d.country") !=
eval("chosen.country");})
.style("fill-opacity", setOpacity);
}
}
};
Here is a snapshot of my incidentsData:
var incidentData =
[
{
"country": "Israel",
"date": 1971,
"incidents": 1,
"": ""
},
{
"country": "Israel",
"date": 1972,
"incidents": 15,
"": ""
},
Here is my totalIncidentsLineGraph:
function totalIncidentsLineGraph() {
modus = "incidents";
var margin = {top: 80, right: 80, bottom: 80, left: 80},
width = 960 - margin.left - margin.right,
height = 500 - margin.top - margin.bottom;
var svg = d3.select("#svg").append("svg")

.attr("height", height);
var incidentsData = svg.append("g");
incidentsData.selectAll(".incidentsData")
.data(incidentData)
.enter()
.append('incidentsData')
.attr('class', 'incidentsData')
.attr('id', function(d) { return d.country, d.date,
d.incidents});
var parse = d3.time.format("%Y").parse;
var x = d3.time.scale().range([0, width]),
y = d3.scale.linear().range([height, 0]),
xAxis = d3.svg.axis().scale(x).tickSize(-height).tickSubdivide(true),
yAxis = d3.svg.axis().scale(y).ticks(4).orient("right");
var area = d3.svg.area()
.interpolate("monotone")
.x(function(d) { return x(d.date); })
.y0(height)
.y1(function(d) { return y(d.incidents); });
var line = d3.svg.line()
.interpolate("monotone")
.x(function(d) { return x(d.date); })
.y(function(d) { return y(d.incidents); });
function type(d) {
d.country = d.country;
d.date = parse(d.date);
d.incidents = +d.incidents
return d;
};
var data = d3.csv("static/data/israel/incidents_linechart.csv", type,
function(error, data) {
console.log(data);
var israel = data.filter(function(d) {
return d.country == "Israel";
});
var unitedStates = data.filter(function(d) {
return d.country == "United States";
});
var iran = data.filter(function(d) {
return d.country == "Iran";
});
x.domain([unitedStates[0].date, unitedStates[unitedStates.length -
1].date]);
y.domain([0, d3.max(egypt, function(d) { return d.incidents;
})]).nice();
var svg = d3.select("svg")
.attr("width", width + margin.left + margin.right)

var colors = d3.scale.category10();

d3.on("mouseover") occurring before mouseover

This is a d3 bar chart. line 162 ,
.on("mouseover", console.log("I am on it"))
should only happen when user is over a bar on the bar chart, but the log is output from the time the page loads.

I added the last two lines here, but still no luck,
var messages = focus.append("g");
messages.attr("clip-path", "url(#clip)");
messages.selectAll("message")
.data(data)
.enter().append("rect")
.style("fill", function(d) {
return colorScale(d.intensityInverted);
})
.attr("class", "message")
.attr("x", function(d) {
return x(d.date);
})
.attr("y", function(d) {
return y(d.distance);
})
.attr("width", function(d) {
return dur(d.duration);
})
.attr("height", function(d) {
return height - y(d.distance);
})
// .on("mouseover", onit);
.on("mouseover", () => console.log("I am now on it for sure!"));
// function onit(d) {
// console.log("I am on it now!")
// }
I suspect the problem is because I am using brushX() and zoom.

When you do this:
.on("mouseover", console.log("I am on it"))
You're passing the result of the console.log function to the callback. Instead of that, you want to pass its reference:
.on("mouseover", function(){
console.log("I am on it")
})
Check this snippet (don't hover over the circle!):
var circle = d3.select("circle");
circle.on("mouseover", console.log("I'm on it!"));
<script src="https://d3js.org/d3.v4.min.js"></script>
<svg>
<circle cx="50" cy="50" r="15" fill="teal"></circle>
</svg>
Now the same code, with the reference to console.log:
var circle = d3.select("circle");
circle.on("mouseover", () => console.log("I'm on it!"));
<script src="https://d3js.org/d3.v4.min.js"></script>
<svg>
<circle cx="50" cy="50" r="15" fill="teal"></circle>
</svg>

The issue is that you are calling the function at the time you are declaring it:
.on("mouseover", console.log("I am on it")) //function call
should be something like this:
.on("mouseover", console.log) //function ref
.on("mouseover", function(d) { console.log("I am on it") }) //function ref

D3.JS: Making plotted line static wrt axis in a 2D plot

I am beginner in D3 and don't know a lot about it.
I am currently trying to plot a 2D line on a graph using D3. I have been successfully able to plot the line, add axis , and even add zoom capabilities to the plot.
I am stuck in making the line hinged to y axis such that you can't just click on it and move it left or right (Currently if you would run the jsfiddle you could click on it and move the plotted line). I would still want to zoom in or out . But it should remain hinged to the y axis. Please let me know if this clarifies my issue.
Thanks!

Add this .on("mousedown.zoom", null) to disable panning:
var myChart = d3.select('body').append('svg')
.attr('id', 'graph')

.attr('height', height + margin.top + margin.bottom)

.attr('transform', 'translate(' + margin.left + ', ' + margin.top + ')')
.call(zoom)
.on("mousedown.zoom", null);//disable panning

Not able to plot rectangles using onclick function on a stack of each bar in stacked bar chart in d3

I am creating a stacked bar chart where stacks of each bar represents the status -"open","wip" respectively.what my requirement is that,triggering click event on each stacks of bar,3 rectangle should appear which represents "sev-high","sev-low","sev-medium" with respective count ...it means clicking on each stacks which represents "status",the total count for that status will get splited up into 3 bars showing "sev-high","sev-low","sev-medium" for that particular status..but here i am not able to plot the rectangle after clicking on stacks...please go through my code and suggest me ...
here is my code...

how to align y axis label in D3

i am trying to create a stacked bar graph.
however i can't seem to get the alignment right.the graph has two axis.
because of the length of the y axis label it is partially blocked.
i tried solving this by using different CSS styles on the label and on the enclosing div,
but they did not have the desired affect.
i created a jsfidel to explain my case.

Implementation of pie chart in d3.js

I have implemented bar chart and line chart in d3.js but now I am trying to implement pie chart as you can see but it is not working so I need your suggestions. Bar chart and line chart are working fine ... Thank you in advance ... here is my code:
