Extract

Most plotting tools tend to load all the data to be plotted into main memory and then use the in-memory data for the actual operations such as plotting. Our Analysis shows that in case of such interactive applications, as the memory usage grows, the response time increases in a significant fashion resulting in poor user interactivity. Further, in cases where the data size exceeds the limits imposed by the available physical memory, the entire data cannot be loaded in memory for performing any kind of operation.
