This is a demo of a Line chart that shows a constantly updating Line chart. It updates every 50 milliseconds with new data. There's only one Line chart object and its data is updated (new data added and the last data-piece removed from the datasets) every 50 milliseconds. If you want to change the delay then open the console (CTRL+SHIFT+J in Chrome) and enter: DELAY = 20 and press enter.
