I want to know if there is a simpler and quicker way to visualize dynamic data. The setup that I require is:
An admin web-interface with forms to feed data.
A public web-page with a table and few charts to display data dynamically.
Live and dynamic display of data.
I know python and I am currently learning django framework.
Solutions which don't require programming skills are also welcome.
Any CMS;
Take a look at google's visualization api.
Visualizing the data client-side requires the use of something along the lines of Raphaël or jqplot, which you can customize to your specific scenario. You can, however, opt to display charts using images and generate them on the server, then switch the images periodically in Javascript.
The other technical hurdle is the way you get data on the client. Typically, you can implement polling via AJAX (easier) or some push mechanism (Comet, for example, though harder and requires server-side specifics). When you get the data on the client, you simply change out the data on the chart or remove and recreate it. When using images, it is as simple as changing the src property on the images, but requires generating the images on the server.
Highcharts provides some really good examples.
Realtime Plot Highcharts
Mostly AJAX shall suffice,but in case you wish to have a tightly coupled system,using Django-chartit might also be an option
When I setout to something very similar, I found these very useful,
Admin theme : Look at these themes and relatively very inexpensive. Big time savers.
These themes already has some built-in graphs/charts. If you want something more complex, D3 JS impressed me. Also look at kendoUI and sencha UI charts.
You can ofcourse build your portal on django but I'm developing on ruby on rails. Good luck!
If you need live data visualization,the best solution is Google Public Data Explorer http://goo.gl/CWbxO . But first of all ,you should learn about DSPL https://developers.google.com/public-data/overview ,the Dataset Publishing Language describes how your data is organized and how you want to show your data(e.g,bar chart ,line chart ,bubble char or else)
you can upload your data via http://www.google.com/publicdata/admin to upload your dataset
after you successfully upload your data,open it in your Public data adamin,explore the data,and you can get a link on the right ,you can embed the chart in your own website too
the chart is ilve,you can find some examples first,mostly,the x axis is by year,and you can describe it yourself
Here is a example of Google Public Data Explorer. http://goo.gl/yZ5Cj

I'm new with ArcGIS. I have done an app with Web AppBuilder to show a map with layers. When I click on an item layer it shows a pop-up with item info. But I want to show more information that I have to get from a database, depending on the clicked item( it could be a csv file instead of a database if it was easier).
I know how to create a web with the ArcGIS Javascript API (following the tutorials) and I know to create widgets (tutorials too..). I known to create a web with Web AppBuilder. But I don't know how to use Javascript API (for example creating a new layer) modifying the code created by the Web AppBuilder.
My idea was to create the web, map and layers with Web AppBuilder and then make modifications in the generated code using the Javascript API.
What is the best approach to show dynamically obtained information when clicking an item?
Thank you.
If the data you want to show when you click a feature in the map is in the same (geo)database as your layers, you could create a Query Layer to join the data with the layer attributes. You will need to know SQL to do this. Also, you will need to use Arcmap (to publish a Mapserver with the query layer) or Arcgis Pro (to publish a webmap with the query layer) so you can query the data. More on query layers you can find in here.
You probably want to give more details of what exactly you are trying to accomplish, with sample data, so others can provide better answer to your question.
I want to display the charts, tables, maps etc from a dhis2 user account unto a web page. I read the web api documentation and tried to use the plugins but they dont work (they seem to be outdated). Anyone have a solution to this?
You may use the Web APIs of dhis2 to fetch data , and then use any Library for building graphs out of that data.
Having to look to all the feed data in the phone harms people's necks. A more comfortable way to see and manipulate it is needed. I would like to do a web viewer to view the up application feed in a browser.
However, I had a look at the REST API and couldn't find a way to obtain it. There is a part where generic "events" are mention. Can I obtain the feed data from there?
Regards
The developer REST APIs do not provide the ability to re-create the UP app's feed.
If you really want to, you could do a close approximation since the APIs provide most of the data that appears in the feed. However, you would have to provide all the styling and assets yourself.
i want to develop a site where user selects various videos and site will render a single video containing all videos in a pre-built template.
what would be the way to go about this (in order to create the movie dynamically from site) ?
what would be the server side framework to use ?
can i use after-effects and have site use it to generate such templates (optional - as i have a friend who works with after effects and can create templates) ?
as i am fairly new to the field any additional information is welcomed.
I'm no expert, but I'm pretty sure you can't do what you described.
Rendering a video consumes huge resources (really huge), so a server park that could
handle this is just not worth it.
However, what you can do is to play the selected videos consecutively. That way, no rendering is necessary.
Also, forget about After Effects, for the same reasons described above.
You can achieve what you want by using a new plugin for After Effects called Templater Bot. From Dataclay's site:
Templater Bot is an enterprise solution for custom video on demand. It works as an automated system. Use it to periodically check for incoming data, pull new data in, and render video as a background process. Or use the command line interface to push data in to create new renders. Once your AE project is prepared, use Bot to customize and render it without operating the After Effects user interface. Developers can create front end applications, such as web or mobile apps, that feed data into Templater's data source, offering a collaborative, custom video content creation solution.
Recline.js seems a great tool to display data on grids, maps, etc.
I'd like to use the grid views, but to be able to save what is displayed to the user on a database. I'm currently using rails for this project.
In the docs, they say how to code a backend to integrate with it (http://okfnlabs.org/recline/docs/backends.html) but i wonder if there's already someone working on it ( I couldn't find it on the web)
Thanks
The Backend object in Recline.js a javascript component that talks to a data source of some kind, typically a web service. The Backend component talks to the interface of that web service, and it doesn't care whether it be programmed in Ruby, COBOL or Java, as long as it knows where to get and send the data, and in what format.
So in short there isn't, and can't really be a ready Rails backend, because the implementation depends more on the specifics of your application -- how to map the data in your database (MySQL?) to a service API Recline can understand, and vice versa.
You can use SOLR with Rails, so I dont know why you couldn't utilize the Recline.js SOLR functionality to search your rails data.
