Yes it is possible: inside JForex you can obtain through api a custom tab, either in the bottom pane or main pane; and then therein you can do everything that java can do, e.g. drawing in any container by overwriting its paint() method and so on. Then you need the data point and map those to the x- and y-axis and so forth.. How to create the tab and some other useful stuff see: viewtopic.php?f=31&t=4830
