问题
I wrote the program on the basis of JFreeChart library. Possibility of change of points of the diagram, creation of new diagrams online, scaling, etc are realized in my program. A problem that the program works slowly if there more than 30 plots. How it is possible to speed up the program?
I can show a code, but I don't know, whether there is a sense. Also I don't know, on what part of a code leaves most of all computer resources. How can I find this parts of code? I work in NetBeans.
