Flot Live Charts (ajax) Flot is a pure JavaScript plotting library for jQuery, with a focus on simple usage, attractive looks and interactive features. The examples here link charts with data from a Django server using asynchronous ajax calls.

This example refreshes all the data into the chart with each call. The browser calls the Django server repeatedly, and receives back asynchronous data messages, each of which contains the full data-set for the chart.

This example adds to the existing data in the chart after each call, deleting older data points to keep a constant duration of displayed data.
