I have a kendo diagram, in that one shape is already there, I have to add the next shapes, and after that next should be added to the Parent Shape or child Shape based on the condition specified dynamically and shape type will also be specified dynamically.
I have kept a button after clicking on that button, the shape is coming but not dynamically.

If i pass the shape type and shape location to which it should get bind. It should give an Shape Connected with that specified location.
Create the shape, then connect it.
// Connect new shape to last added shape
var diagram = … ;
var count = diagram.shapes.length;
var lastAddedShape = diagram.shapes[count-1];
var shape = …;
diagram.addShape(shape);
diagram.connect(lastAddedShape, shape);
Trying to create simple svg canvas using D3 but looking at elements in the console nothing shows up. D3 seems to be loading because from the console when I type d3. I get the options and methods available in D3. But the svg canvas is not being drawn. What am I missing?

You've placed your code within the script tag that has its source attribute set to download D3:

You need to place your code in its own script tag:

I have a time series with a date, an amount and a count column. I just want to plot the aggregate of amount by month and select a month by clicking on the bar, not using the brush.
I thought my objective was pretty simple, but I'm rummaging for days without success. The main issue is that I apply a filter on the chart, but the filter is not taken into account when a redraw the chart.
Thanks for your help.
I'm using :

Interesting solution to this problem.
You probably want .redrawGroup() instead of .redraw() inside that handler, and you'll also need to wrap your range inside a dc.js filter object, specifically RangedFilter: unlike crossfilter's dimension.filter() dc.js's chart.filter() takes an object not an array.
Initial Range selection in DC.js chart
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>

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
I'm using Kartograph.js to load svg map. But I get the following error when page loads:
Uncaught TypeError: Cannot read property 'getAttribute' of undefined

Here is my Code:
<html>
<head>
<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript" src="raphael-min.js"></script>
<script type="text/javascript" src="kartograph.js"></script>
<script type="text/javascript">
function loadMap(){
var map = kartograph.map('#map', 600, 0);
map.loadMap('World.svg')
}
</script>
</head>
<body onLoad="loadMap()">
<div id="map"></div>
</body>
</html>
You need to define the metadata on the svg file.
For example:
<metadata><views><view h="604.816027229" padding="0" w="1000"><proj id="laea-usa" lat0="45" lon0="-100"/><bbox h="321.76" w="532.88" x="746.23" y="918.78"/></view></views></metadata>
If you created the svg with kartograph.py, you might need to add the layers added in the svg as follow:
function loadMap(){
var map = kartograph.map('#map', 600, 0);
map.loadMap('World.svg', function() {
map.addLayer('your_first_layer');
map.addLayer('your_second_layer');
});
}
To find the name of the layers to be added:
Open your svg file as text, for exemple in Firefox and use rightclick, page inspector.
On the second line you'll see : svg > g#something > ...
The name of one of the layer is the "something" after "g#". In the code it is the "id" of the "g" element.
Hope this might help you...
