I'm using java spring for backend of my website. I need to add some auto generating graphs to it. But I'm not sure for what I should look for. Should I use a Javascript library or can I do it in java as a backend function? This is my first time using this functionality.
P.S.
I have to deal with a often updating database to fetch data for those graphs.
Check this answer, I would suggest to go with option 2 and use a javascript library like highcharts.

I am using Django to make a dashboard to show sensor data.
I am using chart.js for that
I am retrieving sensor data of two days or less only.
The problem is that how can I divide my graph for it.I think it might be possible using python time library or Django or something like that if so kindly suggest me some way to do it.
I think that if java script can help us that will be great too.
I just want data parsing based on time to plot and view it nicely.
My company is using QlikSense 3.0 as a backbone for all their Business Intelligence activities. As it turns out one of the graphs (HeatMap) is built using Angular and we want to keep the same view. I was hoping if there is a way we can fetch data from the QlikSense HeatMap graph and just use the same data to render the existing view.
Can anyone help me understand how to fetch data from existing graphs in QlikSense using any API?
I would suggest you to take a look at the Qlik Sense Engine API documentations
You can access the Engine via Java Script/Node JS or ASP.NET
If you want to get the data outside QS then Node JS/.NET are you options (i think someone build and Python library but its 3rd party one)
I'm trying to create dynamic graph inside a mobile cordova angularjs application.
I've done a bit of research and tried several libraries to plot a graph using a websocket protocol with no success.
I'm starting to think its not possible and would need to program a custom one.
Does angularjs support any live streamed graphs for use?
I would like to use something provided by highcharts a live dynamic spline chart.
Thank you very much.
I heard about Dashboard APIs using JavaScript/Jquery, particularly Geckoboard and many others also.
But I don't know how to use it.
I have a Java web application. It is used to collect some data from users and save to database. After that some analysis will be done and display as graphs or some other graphical representations.
The problem is I don't know how to use that for my application.
Do I need to add some Action classes or JQuery/JavaScript.
I tried to add a widget there but it needs a url to the application. Is it with action class URL and does that need to return any JSON data?
Anyone has some idea?
Why don't you try Dashy is a simple angularJs script that let you add custom datasource?
Please note: I'm the developer of Dashy.
I'm looking to use this chart generation library: http://www.jqchart.com/
Ideally, I would prefer to use a PHP charting library for the current project I'm working, but, by the looks of it, this is the only library I've found that can handle what I need to do (given a somewhat unconventional requirement for the charts).
The issue is that I need to get the generated graphs as images (at the moment each graph seems to be a combination of images) to the server so that I can generate some PDF documents, etc.
I'm thinking of attempting to create an image using JS, pushing this back to the server and then generating the PDF although this pretty nasty and will probably cause issues between different versions of the browser.
So now what I'm looking for is a solution that will allow me to generate the graphs and turn them into images on the backend.
Any ideas?
EDIT: For the requirement that led me to rule out a number of other charting libraries, see here: Complex charts in Google Charts
That really isn't all that relevant to the question of processing Javascript on the server, though.
You can render a javascript graph on the server using phantomjs. Here is an example.
Not sure what your requirements are, but I'd check out Google Chart Tools: http://code.google.com/apis/chart/. It's really simple to use. All the data is in the image URL get request, so you can generate charts using client-side JavaScript too.
