I have a svg element to which I want to append an area whose end-points are constant/calculated already. Now If I call this area by passing data to it and then plotting it as function over x-axis it works fine and I also see the color filled-area. However if I mark all end points eg: x0,x1,y0,y1 then the area does not show or doesnt fill color. Is it possible to append constant area to svg and if yes then how? The previous question was deviating so I was asked to make a new question which is specific.Previous Question
Created a fiddle here to show my problem : Problem
var percentArea = d3.svg.area()
// do not want to use this .x(function(d){return x(d.date);})
.x0(0)
.x1(width)
.y0(0)
.y1(height);
svg.append("path")
.datum(data)
.attr("class","area")
.attr("d",percentArea);
Note if possible i do not want to pass data by setting datum here as end points are constant.
I wouldn't try to use the d3.svg.area() path generator for what you're trying to do. If all you want is a background fill you should be able to do that with a simple rectangle. Here's my attempt from your fiddle:
svg.append("rect")
.attr("x", 0)
.attr("y", 0)
.attr("width", width)
.attr("height", height)
.style("fill", "orange");
var margin = {top: 20, right: 20, bottom: 30, left: 50},
width = 960 - margin.left - margin.right,
height = 500 - margin.top - margin.bottom;
var parseDate = d3.time.format("%d-%b-%y").parse;
var x = d3.time.scale()
.range([0, width]);
var y = d3.scale.linear()
.range([height, 0]);
var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom");
var yAxis = d3.svg.axis()
.scale(y)
.orient("left");
var area = d3.svg.area()
.x(function(d) { return x(d.date); })
.y0(height)
.y1(function(d) { return y(d.close); });
var percentArea = d3.svg.area()
// do not want to use this .x(function(d){return x(d.date);})
.x0(0)
.x1(width)
.y0(0)
.y1(height);
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 + ")");

I was trying to refactor this bar chart in d3 to be a horizontal bar chart. I think I've isolated the three areas that need to be changed:
the original scale declarations:
var x0 = d3.scale.ordinal()
.rangeRoundBands([0, width], 0.1);
var x1 = d3.scale.ordinal();
var y = d3.scale.linear()
.range([height, 0]);
The domain definitions:
x0.domain(data.map(function(d) { return d.deviceType; }));
x1.domain(deviceClass).rangeRoundBands([0, x0.rangeBand()]);
y.domain([0, d3.max(data, function(d) { return d3.max(d.whenPurchased, function(d) { return d.value; }); })]);
the rect appending and positioning:
device.selectAll("rect")
.data(function(d) { return d.whenPurchased; })
.enter().append("rect")
.attr("width", x1.rangeBand())
.attr("x", function(d) { return x1(d.device); })
.attr("y", function(d) { return y(d.value); })
.attr("height", function(d) { return height - y(d.value); })
.style("fill", function(d) { return color(d.device); });
I can't seem to get the refactoring right and I think that is because I don't exactly get how domain works for x0 and basically not getting that right has a waterfall effect of everything else not working.
I put the full example here: JSFIDDLE
Here's a quick refactor:
var margin = {top: 20, right: 20, bottom: 30, left: 270},
width = 960 - margin.left - margin.right,
height = 500 - margin.top - margin.bottom;
var y0 = d3.scale.ordinal()
.rangeRoundBands([0, height], 0.1);
var y1 = d3.scale.ordinal();
var x = d3.scale.linear()
.range([0, width]);
var color = d3.scale.ordinal()
.range(["#98abc5", "#8a89a6", "#7b6888", "#6b486b", "#a05d56", "#d0743c", "#ff8c00"]);
var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom");
var yAxis = d3.svg.axis()
.scale(y0)
.orient("left");
// .tickFormat(d3.format(".2s"));
var svg = d3.select("#deviceown-barchart").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 + ")");
var data = d3.csv.parse( d3.select("pre#data").text() );
var deviceClass = d3.keys(data[0]).filter(function(key) { return key !== "deviceType"; });
data.forEach(function(d) {
d.whenPurchased = deviceClass.map(function(device) { return {device: device, value: +d[device]}; });
});
y0.domain(data.map(function(d) { return d.deviceType; }));
y1.domain(deviceClass).rangeRoundBands([0, y0.rangeBand()]);
x.domain([0, d3.max(data, function(d) { return d3.max(d.whenPurchased, function(d) { return d.value; }); })]);

Updated fiddle.
really stucked on this issue for days. I am trying to update my d3 graph to show how long it takes to run a function on a calculator. With the info I get, I will show the time taken and display it on the graph that I previously drew. My issue here now is that I just can't get the graph to update.
Codes for the graph:
var margin = {top: 20, right: 20, bottom: 30, left: 50},
width = 400 - margin.left - margin.right,
height = 300 - margin.top - margin.bottom;
var x = d3.scale.linear()
.range([0, width])
var y = d3.scale.linear()
.range([height, 0]);
var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom");
var yAxis = d3.svg.axis()
.scale(y)
.orient("left");
var line = d3.svg.line()
.x(function(d) { return x(d.date); })
.y(function(d) { return y(d.close); });
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 + ")");
var data = dataone.map(function(d) {
return {
date:d[0],
close: d[1]
};
});
console.log(data);
x.domain(d3.extent(data, function(d) { return d.date; }));
y.domain(d3.extent(data, function(d) { return d.close; }));
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")
.call(xAxis);
svg.append("g")
.attr("class", "y axis")
.call(yAxis)
.append("text")
.attr("transform", "rotate(-90)")
.attr("y", 6)
.attr("dy", ".71em")
.style("text-anchor", "end")
.text("Price ($)");
svg.append("path")
.datum(data)
.attr("class", "line")
.attr("d", line);
Code for update function and update of array:
function updateArray(){
dataone.push(clickss-0.5,clickss);
updateData();
}
function updateData() {
var data = dataone.map(function(d) {
return {
date:d[0],
close: d[1]
};
});
// Scale the range of the data again
x.domain(d3.extent(data, function(d) { return d.date; }));
y.domain([0, d3.max(data, function(d) { return d.close; })]);
// Select the section we want to apply our changes to
var svg = d3.select("body").transition();
// Make the changes
svg.select(".line") // change the line
.duration(750)
.attr("d", valueline(data));
svg.select(".x.axis") // change the x axis
.duration(750)
.call(xAxis);
svg.select(".y.axis") // change the y axis
.duration(750)
.call(yAxis);
}
Please advise on how I can get this to work. I read quite a few guides now but
Couple things:
1.) In your update function, your line generator function is line not valueline.
2.) By looking at your accessor functions, I don't think you meant dataone.push(clickss-0.5,clickss); but rather dataone.push([clickss-0.5,clickss]);. You need an array of arrays.
In addition, you don't need to map your dataone array to another structure. Just change your accessors:
x.domain(d3.extent(data, function(d) {
return d[0];
}));
y.domain(d3.extent(data, function(d) {
return d[1];
}));
...
var line = d3.svg.line()
.x(function(d) {
return x(d[0]);
})
.y(function(d) {
return y(d[1]);
});
Here's your code working and cleaned up a bit:

the line serie is displayed, but the scatter serie is not being displayed.
Can someone tell me what's wrong?
thanks in advance.
In your scatterSerie() function, your select statement doesn't add up.
There's no such thing as a 'dot' element. You'll want to select all elements with class 'dot' like so (think jQuery):
svg.selectAll(".dot")
.data(data)
.enter().append("circle")
.attr('class','dot')
.attr("r", 3.5)
.attr("cx", function(d) { return x(d.date); })
.attr("cy", function(d) { return y(d.close); });
Don't forget to set that 'dot' class to your newly added elements, otherwise your future updates might go south.
One other thing you might wanna look into is the style of your circles. Right now they have no defined stroke color, stroke-width or fill. You can add those as CSS rules or add them within your d3 code.

To achieve our requirement I've added one thing,i.e.
(+d[name])/2000000 while assigning the value I'm just dividing it to fit to our scale. y domain is set to very big number like near to one Crore.
That's the CSV file: http://goo.gl/ZVVjD
I've this problem only for bar chart. The line chart works fine. I don't know how to modify this one.
Please,help me to understand where I'm wrong.

Thank you very much!
I don't believe x.rangeBand() works for time scales. Try replacing it with with a fixed pixel value of 2 or 3.
