Does a module for real-time data plotting exist? There are several Drupal modules that allow to plot /chart data stored in database tables. Is there any module that can chart or plot data in real-time? For a specific example, I have a mobile application that is reading sensor data (say from an accelerometer) and sends that to the Drupal server. I want to plot the data as and when updated in real-time or near real-time. Does any specific module that can do this exist?
