In my project I work on a web app that shall provide interactive charts to the user. Interactive is meant in that way that the user can adjust single data points by dragging them around in chart.
More specifically, assume a line chart consisting of six data points. The user clicks one data point and drags it to different coordinates within the chart (drag and drop). Afterwards the line should be rendered again considering the adapted coordinates.
I had a look into Chart.js already but found that this feature is not provided out-of-the-box. I rather have to implement that myself.
Are you aware of any chart library for JS that provides such feature?
UPDATE
Meanwhile I found two potential solutions:
Plugin for Highcharts
Draggable charts of FusionCharts
You can take a look to D3.js, it's battery-included and drag&drop is supported too.
But you have to make the chart in HTML/CSS yourself.

We are developing a web application using Spring+Tiles. We have a requirement that we have to create a bar graph in a jsp page. We searched a lot on web regarding this issue. Means how we can create a bar graph using Open source Charts API. We found many suggested APIs like JFreeChart, charts4j and etc.
But we are not sure which one to use. Actually our requirement is we have to create a bar graph which can be drillable.
Please help us. If you could give any examples that will be highly appreciated.
Thank you very much in advance. Thanks a lot.
I would recommend you to use the rest services and send the json to highcharts OR D3.js OR DDChart, its the best thing to do in your case below link can do what you want :
http://www.highcharts.com/demo/column-drilldown
Highchart (licence) : http://jsfiddle.net/yPVX9/2/
D3 (free) : http://jsfiddle.net/mcuepavh/1/
DDChart (free) : http://kiersimmons.com/DDChart/index.html
You can try FusionCharts for a drill down chart.
Have a look to this and you can use this in your application : Fusion Charts Linked Charts. Regarding licensing issues,you may get in touch Sales Team.
Apart from that, you can use Raphael.js . Start from the basics say try creating a small rectangle, fill some color, opacity, binding some events,etc. With a day effort you can make a simple bar chart. Once you make a bar chart, attach an event to clear your container and redraw another bar chart with the drill down data. Thats the concept you need for your drill-down.
Having said that, I would still recommend you to use Fusion Charts because they takes care of some smart things - like space management of the bars, the intervals, the colour codes of the bars(if not hard-coded), axis part... Its a finished product which abstracts you from the technical obstructions and give your application a beautiful add-on.
I want to create an animated pie chart in JavaScript. I have done some R&D myself and found the Google Charts API.
But my major concern is the actual data is sent to the Google server for creating the charts. I am concerned about sending my data to a third party.
If you're concerned about sharing data with a third party, you might consider an offline charting library, like ZingChart. It gives you the ability to create animated pie charts quickly and easily without the need to transfer any of your data to a third party. This charting library works offline, and is dependency free. There are a number of animations that can be applied to the various types of charts, including pie charts. Check out this animated pie chart demo.
Lists of the different animation effects, methods, and sequences can be found on the animation docs page.
I'm a member of the ZingChart team, so please feel free to ask if you have any questions! :)
I suggest you use jPlot! You can do Pie and Donut Charts, Bar Charts, Line Charts and much more!. See the API here.
A DEMO here.
D3pie is also a good option
They also have a generator that you can use if you want to build your an example and work from there.
I am trying to learn D3 JS and how it can be applied in current application.I am new to this application.
While going through the application I found that there is already a feature providing data visualization in the form of graphs using EXT Js charts.
Could anybody help me understand the advantage of data visualization using ext js over D3 JS and is there any reason for going with one over other? Thanks in advance.
ExtJS is a commercial web app framework for many things including data visualization. D3.js is an open source low level library for creating svg-based charts.
The first question you need to figure out is if you only want charts or all the features that come with ExtJS.
If you just want to draw standard charts (bar, line, area, pie etc.) you may consider using highcharts, google charts, or a higher level library on top of d3.js such as nvd3.js or Rickshaw since they are easier to use. Otherwise if you want a very non-standard and customized chart, d3.js is very powerful for implementing any possible kind of visualization.
D3 is just for visualization, ExtJS is a full framework that hast a lot of other components (grids, windows, layouts, etc...).
Also ExtJS doesn't get well with other libraries, since it overrides several things in the global CSS.
Therefore, if you have a full page that has more than just graphs... feel free to use ExtJS for the whole page, but if you already have something else on the page, then go for D3.
I'm looking for an library, to generate charts on client side.
I found a lot, by searching on web and stackoverflow, like here
https://stackoverflow.com/questions/2227421/good-javascript-library-for-drawing-charts-using-json
or this very good collection:
http://sixrevisions.com/javascript/20-fresh-javascript-data-visualization-libraries/
There are so much alternatives, I'm a bit overwhelmed. Which one can use JSON data, which one is up to date, which one is easy to use (because I'm absolutely new on this topic), which one is robust, works on mobile phone (or not), which project is still alive, etc.
I need different chards, an line chart is mandatory. Also zoom in and zoom out is mandatory.
So I took a closer look on jqplot an flot.
Both providing zoom, but it looks like zooming is more an scaling. Which means: the granularity will not change by zoom in.
Because the graph will have a lot of data/points, i need to consolidate informations before sending them to the client. By zooming in, I need to rise the granularity, so the chart should be able to process new data for the zoomed area. (I hope I've made myself clear.)
Thanks for any kind of attention.
Raphael.js http://raphaeljs.com/
HTML5 Graph http://chrisvalleskey.com/html5-graph/
Google Visualization API: http://code.google.com/apis/chart/interactive/docs/gallery.html
Flot: http://code.google.com/p/flot/
Unfortunately there is no helpful answer, so I like to write down, what i learned the last days for this question.
jqPlot and frot are supporting zooming at an basic level. That means, it's more an scaling.
By looking at the google groups for qjPlot and flot, the support for jqPlot is better (lot's of unanswered questions at the flot group).
jqPlot has an better axis-label-handling by zooming.
jqPlot also provides hooks. By using those hooks, it's seems to be possible to combine zooming and loading new JSON data in order to get an better granularity of the zoomed view.
Has anyone seen an open-source library that produces charts similar to Github.com's commit timeline charts? Check out this profile (picked one at random) and note the bar graphs below each project.
I've been trying to dominate Flot into behaving correctly but it just doesn't have the flexibility of formatting options to come up with a decent clone. Personally, I'd prefer a Javascript implementation but I'm open to looking at server-side stuff as well.
Definitely has to be a stand-alone implementation, the application is headed to a network separated from the Internet, so Google Charts API is out of the question.
I'd suggest using jQuery Sparklines. You'll need to create two separate graphs and position them on top of one another (one for the blue bars, another for the gray bars). You'll also need to make the dotted line/legend an image, but github also uses an image for that.
Here are some decent values to get you started:
EDIT: I originally overlapped two separate sparklines with relative positioning, but it would be better to use the "composite" option to draw two graphs on the same canvas.
