While all the tools we’ve discussed in this article support live charts, FusionCharts leads the pack with its out-of-the-box features. FusionCharts supports tons of different types of charts, graphs, and maps and comes with ready-to-use code. When it comes to live charts, FusionCharts lets you define your desired update interval and refresh interval. Additionally, live charts or data-streaming charts created with FusionCharts fetch data from the server automatically, and they update at a specified interval without needing any page refreshers.
Another great feature of FusionCharts for live charts is that it lets you write your own message logger and alert manager. The message logger allows you to display real-time messages in a specialized chart window. The alert manager helps you define actions based on the data points reaching critical values in pre-defined ranges. FusionCharts also lets you define how and when your live charts with multiple datasets updates.
