Correct. The rendering part has already been optimized in JBT by using FastXYChart. Effectively, no matter how large the data set is, the rendering time will be about the same, which is about 2 seconds on my machine. If you use a standard JFreeChart library, it would be minutes and hours to render such quantities of data. However, JBT still loads all these millions of data points into JFreeChart structures, on the initial pass. This is where all the time is spent. -- You received this message because you are subscribed to the Google Groups "JBookTrader" group. To post to this group, send email to [email protected].
