I'm having trouble with connecting to the c3.js library. I followed the instructions on c3js.org but it won't work. I used a simple example from the website but it isn't showing a thing. I load like this:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="../css/c3.css">
<script src="http://d3js.org/d3.v3.min.js" charset="utf-8"></script>
<script src="../js/c3.min.js"></script>
</head>
<body>
<div id="chart"></div>
var chart = c3.generate({
bindto: '#chart',
data: {
columns: [
['data1', 30, 50, 70, 90],
['data2', 20, 40, 60, 80]
]
}
});
</body>
</html>
the problem is i can't see a chart. I only see the code i entered starting from my var.
Thank you every one
Works perfectly well for me. See this fiddle.
Are you sure you're setting this to the correct url for your setup:
../js/c3.min.js
The D3 is off a CDN but your C3 is off a local path, so check that path is resolving (open Developer Tools in your browser & check for errors).
In the fiddle I also included the c3.css, which I notice your code hasn't got.
I think the path to stylesheet is incorrect.
../ may have to be something else, depending on where you have put your c3.js files

I am having alot of trouble getting c3 to work in my web page. My code for the graphing is right, it just wont load anything and I am guessing this is due to me not having the right script src. Does anyone have a starter file for using c3, or the code I would need to load it in. Or is there a CDN I could reference?
Here is a quick starter file
<!DOCTYPE html>
<html lang="en">
<head>
<title>C3</title>
<meta charset="utf-8" />
<link href="https://cdnjs.cloudflare.com/ajax/libs/c3/0.4.10/c3.min.css" rel="stylesheet" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/3.5.6/d3.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/c3/0.4.10/c3.min.js"></script>
</head>
<body>
<div id="chart"></div>
<script>
var chart = c3.generate({
data: {
columns: [
['data1', 30, 200, 100, 400, 150, 250],
['data2', 50, 20, 10, 40, 15, 25]
]
}
});
</script>
</body>
</html>
But I would recommend, getting stable versions from the respective sites or GitHub projects.
I am learning D3.js, and I have the following code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>D3 Graphic</title>
</head>
<body>
<script src="http://d3js.org/d3.v3.min.js" charset="utf-8"></script>
</body>
</html>
I am using Chrome as a browser on my mac. Am I making an obvious mistake? Thank you!
There is nothing really wrong per-se with your code, other than the fact that it will do nothing (and I personally would put the 'script src' tag in the head section). You have simply written a HTML document which then loads in the D3.JS Javascript library.
What you now need to do is start using the library by issuing some D3 commands to create HTML/DOM elements from data. There is plenty to read up on the internet (try dashingd3js.com) but to get you started here is a v.simple starter for 10 expanding on your code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>D3 Column Chart</title>
<script src="http://d3js.org/d3.v3.min.js" charset="utf-8"></script>
</head>
<body>
<div id="chartarea"></div>
<script type="text/javascript">
// Some random data
var data = [0.27, 0.5, 0.1, 0.15, 0.3, 0.21, 0.25, 0.94, 0.04, 1.00];
var svg = d3.select('#chartarea')
.selectAll('div')
.data(data)
.enter()
.append('div')
.attr('class', 'bar')
.style('height', function (d) {
return d * 400 + 'px';
});
</script>
</body>
</html>
The above should create a v.simple column chart using HTML DIV's. You can then move on to more advanced implementations to generate SVG components.

I'm making an html page with several examples of charts that I will be using. On the page I have a Dimple line graph, a pie chart, a wordcloud etc. When I try to add a second dimple graph - this time a bar graph, the first dimple line graph that I already have on the page is drawn on top of my bar graph:
My HTML file looks like this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>D3 Graphs</title>
<link rel="stylesheet" type="text/css" href="_/base.css">

<script type="text/javascript" src="_/d3.layout.cloud.js"></script>
</head>
<body>
<div id="chartContainer">
<h1>Hot Topics Line</h1>
<script type="text/javascript" src=CurvyLine.js></script>
</div>
<h1>Hot Topics Pie</h1>
<div id="chart">
<script type="text/javascript" src=Pie.js></script>
</div>
<div id="wordCloud">
<h1>Clickable Word Cloud</h1>
<script type="text/javascript" src=WordCloud.js></script>
</div>
<div id="bar">
<h1>Clickable Word Cloud</h1>
<script type="text/javascript" src=WeekBar.js></script>
</div>
</body>
</html>
Without adding the bar chart at the end, the line graph displays properly at the top of the page above the pie chart. However, with the bar chart added, both the line and bar graph are drawn inside the "bar" div. Can anyone help with this please? Here is my line graph js file:
var svg = dimple.newSvg("#chartContainer", 590, 400);
d3.tsv("data/tweet_example.tsv", function (data) {
//data = dimple.filterData(data, "Owner", ["Aperture", "Black Mesa"])
var myChart = new dimple.chart(svg, data);
myChart.setBounds(60, 30, 505, 305);
var x = myChart.addCategoryAxis("x", "Month");
x.addOrderRule("Date");
myChart.addMeasureAxis("y", "Tweets");
var s = myChart.addSeries("Topic", dimple.plot.line);
s.interpolation = "cardinal";
myChart.addLegend(60, 10, 500, 20, "right");
myChart.draw();
});
and here is my bar graph js file:
var svg = dimple.newSvg("#bar", 800, 410);
d3.tsv("data/tweet_example2.tsv", function (data) {
//data = dimple.filterData(data, "Owner", ["Aperture", "Black Mesa"])
var barChart = new dimple.chart(svg, data);
barChart.addCategoryAxis("x", ["Day", "Topic"]);
barChart.addMeasureAxis("y", "Tweets");
barChart.addSeries("Topic", dimple.plot.bar);
barChart.addLegend(65, 10, 510, 20, "right");
barChart.draw();
barChart.draw();
});
Your problem is that you are using the same global name svg to hold references to two different charts. When your second piece of code runs, it overwrites the svg value that you had from the first piece of code, and when the .tsv() callback returns, it finds a reference to the second graph.
Simplest solution: use different names for svg variable in both pieces of code: svg1 and svg2 will be fine.
Most elegant solution: use some kind of namespace management, such as wrapping both pieces of code in immediately called functions:
function() {
// your first chunk of code here
}()
function() {
// your second chunk of code here
}()
This way you will have two svg variables local to their own scopes
This is driving me nuts. Iv followed tutorials and I cant get this thing to do the simplest of actions.
Im just trying to get started. Iv got a skeleton page, a bare bones JSON file and the D3 V3 library loaded.
I can see from the inspector that everything loads fine. The JSON loads fine, but nothing happes. Im just trying to print some words into a few li elements, but i get nothing. I can see that the ul is appended to the page, but nothing else.
There's no JS errors, or anything to guide me. Just a blank page.
What am I doing wrong here?!

and my JSON file
{

}
Your var data is not in correct format. D3.js assumes you will pass list to it but you provide an object. One simple fix to get you started would be to change status.json to:
[{
"status": "OK",
"name": "TEST A"
}]
From the API docs: https://github.com/mbostock/d3/wiki/Selections#wiki-data
selection.data([values[, key]])
Joins the specified array of data with the current selection. The
specified values is an array of data values, such as an array of
numbers or objects, or a function that returns an array of values.
Has anyone had any luck with this?
I copied and pasted the exact example code here http://www.jqplot.com/deploy/dist/examples/barTest.html into my text editor. I added all the .js files and .css file required. when I run the page in any browser, I am not seeing the bars or the animation. I have looked at the source code on the above URL as well to see how it works. Could someone tell me why I can the animated bar chart on the URL but not from my desktop? What's different? Here is the exact code I copied:

here is what I see in the browser after running that code:
Thanks
For anyone interested, I've found the answer. The example code taken from the barchart.html page in my post doesn't appear to need the conditional syntax (below) in order to animate the bars:
$.jqplot.config.enablePlugins = true;
// Only animate if we're not using excanvas (not in IE 7 or IE 8)..
animate: !$.jqplot.use_excanvas,
From the animate example on the examples page , the following code will do the trick:
animate: true,
// Will animate plot on calls to plot1.replot({resetAxes:true})
animateReplot: true,
I read the entire documentation and was doing a lot of playing around with the code. Eventually, I got to the full "examples" page (not the few listed on the tests and examples page which I initially viewed since it was listed first in the documentation). I really wanted to understand the plugin code since the developer took so much time to really provide a ton of info, comments and updates to his code base.
