Hello,

I'm a new user and have a couple of questions for anyone that may care to answer them which will determine whether Jfreechart will suit my needs and I will purchase the developer's guide :

1) Is it possible to plot a vector field directly using JFreeChart (similar to the 'quiver'function in Matlab if anyone is familair with it ) or will I have to combine several components of JFreeChart to do this. I have an array of vectors, their directions are all the same but the lengths are all diffent, as is their co-ordinates, but I would like to plot them using JFreeChart if possible.

2) Is it possible to overlay several differing types of charts e.g. a line chart over laying a bar graph, in effect having two different charts on one graph.

Many thanks to anyone that reads or replies too.

Kerry
