Does JFreeChart support real-time charting?
Not really. JFreeChart includes an event-notification mechanism that ensures that charts are updated whenever the dataset is updated. However, the chart is completely repainted for each update, which limits the “frames per second” rate that you can achieve with JFreeChart. Typically, updating once per second is fine, but updating multiple times per second results in high CPU load. If you want to pursue this, do some performance testing with your specific configuration and use cases.
