D3 Added Circles to a MultiLine Chart - Circles on top of Circles - d3.js

I'm having an issue where I'm plotting circles on a multi-line chart which has a different color for each line (circles match the colors). The catch is the way I have the function I'm writing circles on top of circles - which is an issue when I try to hide specific ones.
I want to plot circles based on then name but I'm unsure how to limit the above D3 functions to one name only - currently it plots all circles for each line.
Is there a way to use d.name to limit the plotting to one name each time?
thanks

I think d3.nest is what you want:
var names = d3.nest()
.key(function(d){ return d.name; })
.entries(data);
var data = [

exit().remove() is not removing the first bar

Whenever the slider is dragged and a new date is selected it does not redraw the first bar, it redraws all the other bars. For example, try date 09/06 and then 09/17. The first bar for id 54042 will not redraw. This is the link to my bl.ocks http://blockbuilder.org/fall16mis/87a39bc00b1b356f78dfd0954f345444

You cannot use the whole object in the key function:
var bars = chartGroup.selectAll(".bar")
.data(data, function(d){
return d;
});
The API explains it:
key function may be specified to control which datum is assigned to which element, replacing the default join-by-index, by computing a string identifier for each datum and element. (emphasis mine)
Therefore, instead of using the whole object, use a property (like the id):
var bars = chartGroup.selectAll(".bar")
.data(data, function(d){
return d.id;
});

y axis ticks disappear in responsive chart in d3.js v4

I had perfectly adequate ticks in my earlier statically sized plot using d3.js v4; once I made it resizable, the ticks and values disappeared from the y axis.

The ticks are now gone on the y axis. I've added the .tick attribute to the y axis, but no joy.
How do I get my y axis ticks back on this responsive version of the chart? TIA
Posted later: Anyone? My non-responsive version of the code is drawing correctly; "responsifying" it makes the y-axis ticks and units disappear. I've tried almost every permutation of command ordering and placement, but no luck.
Whats happening here is your Y axis ticks are getting hidden because they're not in the viewport. What you need to do is put all the elements in your svg in a <g> wrapper and translate it by left and top margins.
Here's a fiddle
var chartDiv = document.getElementById("chart");
var svg = d3.select(chartDiv).append("svg");
var g = svg.append('g');
function render() {
$('svg').empty();
// Extract the width and height that was computed by CSS.
var width = $('#chart').width();
var height = $('#chart').height();
// Use the extracted size to set the size of an SVG element.
svg
.attr("width", width)
.attr("height", height);
// set the dimensions and margins of the graph
var margin = {
top: 20,
right: 20,
bottom: 50,
left: 40
};
width = width - margin.left - margin.right,
height = height - margin.top - margin.bottom;
// parse the date time
var parseTime = d3.timeParse("%m/%d %H:%M");
// set the ranges
var x = d3.scaleTime().range([0, width]);
var y = d3.scaleLinear().range([height, 0]);
// define the line
var valueline = d3.line()
.x(function(d) {
return x(d.time);
})
.y(function(d) {
return y(d.solar);
});
// Get the data
var data = [{
'time': '11/30 04:55',
'solar': -1.1
}, {
'time': '11/30 05:00',

}]
// format the data
data.forEach(function(d) {
d.time = parseTime(d.time);
d.solar = +d.solar;
});
console.log(data)
// Scale the range of the data
x.domain(d3.extent(data, function(d) {
return d.time;
}));
var yExtent = d3.extent(data, function(d) {
return d.solar;
})
y.domain(yExtent);
g.attr('transform', 'translate(' + margin.left + ',' + margin.top + ')');
// Add the valueline path.
g.append("path")
.data([data])
.attr("class", "line")
.attr("d", valueline);
// Add the X Axis

Happy coding :)
Got it - the axis ticks were disappearing off the left edge of the window - fixed that with a transform/translate:
// Add the Y Axis
svg.append("g")
.attr("transform", "translate(40 ,10)")
.call(d3.axisLeft(y));
...with a similar translation of the x axis and path to match.
Also, the axis scale now appeared with an extent of 0 to 1.0, as it wasn't being passed out of the file read loop since it was an asynchronous operation. Bringing the svg.append's into the data read loop restored my "normal" units to the axis.

Multiple line chart issue from json

Following is my code. I have been trying to plot humidity and dew point in basis of months in the axis. But I am getting an error of data undefined and also the month in the axis comes in number.

I am not sure how will i solve it. Can anyone please help. I am sharing the data file with the current issue I am facing.
I have attached the model data the way it should look like:
Thanks in advance.
For your question on Date format for the X axis , sorry i put an answer because i can't comment (need more reputation).
I think you need to do something like this
chart.xAxis
.tickFormat(function(d) {
return d3.time.format('%b')(format(d));
});
That will display only the month.

D3.js How to hide/show line when click select options?

I tried to use D3.js to draw lines when you click on different checkbox. It will get data of that option. Here is an example I used D3 multi-series line chart with tooltips and legend. I have got the specific data object that is corresponding the checkbox I choose. Howevery, I don't know how to draw it on svg. Please help me and I will appreciate you so much.
I also find a website "www.cotrino.com/starpaths/" that shows the final effect I want to implement.

You need to create your line variable:
var myLine = svg.append("path");
And then, inside redraw(), changing it according to the option selected:
myLine.datum(adata.values)
.attr("d", line);
Here is a demo plunker: https://plnkr.co/edit/YjGO9TLDBXj13JQuO5bm?p=preview
PS: I changed your x-scale range:
var x = d3.scaleTime().range([margin.left, width]);
And also added a call to redraw() when the code runs for the first time.

D3.JS - how do I add gridlines to my pie chart

I have extended the pie-chart example at:
with pies that vary in radius depending on a percentage. I would like to add gridlines (circles) every 20 percent, but I can't figure out how.
here is the updated csv:
age,population,percent
<5,2704659,67
5-13,4499890,38
14-17,2159981,91
18-24,3853788,49
25-44,14106543,71
45-64,8819342,88
=65,612463,64
and here is the updated code with pie-parts of different radius:
<!DOCTYPE html>
<meta charset="utf-8">
<style>
body {
font: 10px sans-serif;
background: #333;
}
.arc path {
stroke: #fff;
stroke-width: 2px;
}
.arc grid {
stroke: #fff;
stroke-width: 1;
stroke-dasharray: 5,5;
}
.arc text {
fill:#fff;
font-size:12px;
font-weight:bold;
}
.arc line {
stroke: #fff;
}
</style>
<body>
<script src="d3.js"></script>
<script>
var width = 960,
height = 500,
radius = Math.min(width, height) / 2 - 10;
var color = d3.scale.ordinal()
.range(["#98abc5", "#8a89a6", "#7b6888", "#6b486b", "#a05d56", "#d0743c", "#ff8c00"]);
var arc = d3.svg.arc()
.outerRadius(function(d) { return 50 + (radius - 50) * d.data.percent / 100; })
.innerRadius(20);
var pie = d3.layout.pie()
.sort(null)
.value(function(d) { return d.population; });
var grid = d3.svg.area.radial()
.radius(150);
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width / 2 + "," + height / 2 + ")");
d3.csv("data.csv", function(error, data) {
data.forEach(function(d) {
d.population = +d.population;
d.percent = d.percent;
});
var g = svg.selectAll(".arc")
.data(pie(data))
.enter().append("g")
.attr("class", "arc");
g.append("path")
.attr("d", arc)
.style("fill", function(d) { return color(d.data.age); });
g.append("text")
.attr("transform", function(d) { return "translate(" + arc.centroid(d) + ")"; })
.attr("dy", ".35em")
.style("text-anchor", "middle")
.text(function(d) { return d.data.age; });
});
</script>
First set the number of ticks:
var numTicks = 5; // Each tick is 20%
Then create the data to create the gridlines:
var sdat = [];
for (i=0; i<=numTicks; i++) {
sdat[i] = (radius/numTicks) * i;
}
And then you can use a function to create the radial gridlines, and you can call it from within the d3.csv block:
addCircleAxes = function() {
var circleAxes, i;
svg.selectAll('.circle-ticks').remove();
circleAxes = svg.selectAll('.circle-ticks')
.data(sdat)
.enter().append('svg:g')
.attr("class", "circle-ticks");
// radial tick lines
circleAxes.append("svg:circle")
.attr("r", String)
.attr("class", "circle")
.style("stroke", "#CCC")
.style("opacity", 0.5)
.style("fill", "none");
// Labels for each circle
circleAxes.append("svg:text")
.attr("text-anchor", "center")
.attr("dy", function(d) { return d - 5 })
.style("fill", "#fff")
.text(function(d,i) { return i * (100/numTicks) });
};
