plotting data points on waves from dynamically generated data using d3.js

i have plotted dynamic waves based on randomly generated data in d3.js. I am using "dot" (svg.selectAll("dot")) element to represent the data point(x and y axis) on the waves. Based on setinterval method my data is getting updated every 200ms and i am transforming the data from right to left. But the data points(dots) that i added to the waves are not moving along with the waves, they are fixed(not moving) and only waves are moving.
here's the code:
https://jsfiddle.net/rajatmehta/tm5166e1/4/
function updateData() {
var newData = GenData(N,lastUpdateTime);
lastUpdateTime = newData[newData.length-1].timestamp;
var newData2 = GenData2(N,lastUpdateTimeNew);
lastUpdateTimeNew = newData2[newData2.length-1].timestamp;
for (var i=0; i<newData.length; i++){
console.log(globalData.length);
if(globalData.length>99){
globalData.shift();
}
globalData.push(newData[i]);
}
for (var i=0; i<newData2.length; i++){
console.log(globalDataNew.length);
if(globalDataNew.length>99){
globalDataNew.shift();
}
globalDataNew.push(newData2[i]);
}
//code for transition start
x1 = newData[0].timestamp;
x2 = newData[newData.length - 1].timestamp;
dx = dx + (x(x1) - x(x2)); // dx needs to be cummulative
x1New = newData2[0].timestamp;
x2New = newData2[newData2.length - 1].timestamp;
dxNew = dxNew + (x(x1New) - x(x2New)); // dx needs to be cummulative
d3.select("path#path1")
.datum(globalData)
.attr("class", "line")
.attr("d", valueline(globalData))
.transition()
.ease("linear")
.attr("transform", "translate(" + String(dx) + ")");
d3.select("path#path2")
.datum(globalDataNew)
.attr("class", "line")
.attr("d", valueline2(globalDataNew))
.transition()
.ease("linear")
.attr("transform", "translate(" + String(dxNew) + ")");
svg.select(".x.axis").call(xAxis);
}
I am new to d3.js, so dont have much idea about this.

Two problems:
You are not appending the circles correctly: you cannot append a <circle> element to a <path>element. You have to use an "enter" selection, appending them to the SVG (or a group element):
chartBody.selectAll(null)
.data(globalData)
.enter()
.append("circle")
.attr("class", "dot1")
.attr("r", 3)
.attr("cx", function(d) {
console.log(d)
return x(d.timestamp);
})
.attr("cy", function(d) {
return y(d.value);
});
In the update function, select those circles by class:
d3.selectAll(".dot1")
.data(globalData)
.transition()
.ease("linear")
.attr("transform", "translate(" + String(dx) + ")");
Here is your code with those changes:
var lastUpdateTime = +new Date();
var lastUpdateTimeNew = +new Date();
var GenData = function(N, lastTime) {
var output = [];
for (var i = 0; i < N; i++) {
output.push({
value: Math.random() * 10,
timestamp: lastTime
});
lastTime = lastTime + 1000;
}
return output;
}
var GenData2 = function(N, lastTime) {
var output = [];
for (var i = 0; i < N; i++) {
output.push({
value: Math.random() * 20,
timestamp: lastTime
});
lastTime = lastTime + 1000;
}
return output;
}
var globalData;
var globalDataNew;
// plot the original data by retrieving everything from time 0
data = GenData(50, lastUpdateTime);
dataNew = GenData2(50, lastUpdateTimeNew);
lastUpdateTime = data[data.length - 1].timestamp;
lastUpdateTimeNew = dataNew[dataNew.length - 1].timestamp;
globalData = data;
globalDataNew = dataNew;

PS: You have to append new circles as the lines move to the left. However, this is another issue.

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.

.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

Hightlight the respective layer in stacked Bar chart when mouseover on legend in d3

I have Done a stacked Bar chart now I am extending the Chart feature as when mouseover on the legend the Respective Bars should highlight.
The Problem I am facing is the mouseover event is working on the Last legend only but but highlighting the every rect layer in chart.
The Problem shown in below fig. This image is when I mouseover on D_Lines Legend Rect
My Code part is
var svg = d3.select("body")
.append("svg")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom)
.append("g")

Can any one help me to overcome this problem.

You are appending the same class : color-9999CC to all your rect elements, so once you hover the last legend item having color : #9999CC all rect element will be selected.
To create the required class properly, you can add the corresponding color info to each element in your layers object while creating it.
I added a color property that has as value the color of the corresponding headers item:
var layers = d3.layout.stack()(
headers.map(function (count) {
return fData.map(function (d,i) {
return { x: d.orders, y: +d[count] , color: colorScale(count)};
/*color = current headers item color */
});
}));
Then while creating your rect items you can add to each element a class by accessing its color property like this:
var rect = layer.selectAll("rect")
.data(function (d) { return d; })
.....
.attr("class", function (d) {
return "rect bordered " + "color-" +d.color.substring(1);
});
complete code:
var margin = {top:10, right: 10, bottom: 80, left: 50},
width =960,
height=650;
var svg = d3.select("body")
.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 + ")");

add circle in a spiral chart with d3js with line connecting to center

hi I created a spiral chart in d3.js, and I want to add circle to different position of the spiral lines.according to there values.
circle closes to the center will have highest priority.
any idea how to do that.
here is the code which i wrote
var width = 400,
height = 430
num_axes = 8,
tick_axis = 1,
start = 0
end = 4;
var theta = function(r) {
return -2*Math.PI*r;
};
var arc = d3.svg.arc()
.startAngle(0)
.endAngle(2*Math.PI);
var radius = d3.scale.linear()
.domain([start, end])
.range([0, d3.min([width,height])/2-20]);
var angle = d3.scale.linear()
.domain([0,num_axes])
.range([0,360])
var svg = d3.select("#chart").append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width/2 + "," + (height/2+8) +")");
var pieces = d3.range(start, end+0.001, (end-start)/1000);
var spiral = d3.svg.line.radial()
.interpolate("cardinal")
.angle(theta)
.radius(radius);
//svg.append("text")
// .text("And there was much rejoicing!")
// .attr("class", "title")
// .attr("x", 0)
// .attr("y", -height/2+16)
// .attr("text-anchor", "middle")
//svg.selectAll("circle.tick")
// .data(d3.range(end,start,(start-end)/4))
// .enter().append("circle")
// .attr("class", "tick")
// .attr("cx", 0)
// .attr("cy", 0)
// .attr("r", function(d) { return radius(d); })
svg.selectAll(".axis")
.data(d3.range(num_axes))
.enter().append("g")
.attr("class", "axis")
.attr("transform", function(d) { return "rotate(" + -angle(d) + ")"; })
.call(radial_tick)
.append("text")
.attr("y", radius(end)+13)
.text(function(d) { return angle(d) + "°"; })
.attr("text-anchor", "middle")
.attr("transform", function(d) { return "rotate(" + -90 + ")" })
svg.selectAll(".spiral")
.data([pieces])
.enter().append("path")
.attr("class", "spiral")
.attr("d", spiral)
.attr("transform", function(d) { return "rotate(" + 90 + ")" });
function radial_tick(selection) {
selection.each(function(axis_num) {
d3.svg.axis()
.scale(radius)
.ticks(5)
.tickValues( axis_num == tick_axis ? null : [])
.orient("bottom")(d3.select(this))
d3.select(this)
.selectAll("text")
.attr("text-anchor", "bottom")
.attr("transform", "rotate(" + angle(axis_num) + ")")
});
}

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.
