I am using the MASON (and therefore JFreeChart) histogram capabilities to chart some values on my own, completely removed from my agent simulation. (The simulation writes data to a file, which I read at a later time). I'm doing it this way for various un-related reasons. My problem is I want to show one "bar" as 1, the other as 2, then 3, and so on, the height of the bar represents the frequency which that number appears in my simulation. But The chart that is produced from the HistogramGenerator spreads the bars over a range, which is awkward to read. Is there a way to make each "bar" represent one number, or more so, is there a way to give the developer more control over the domain scaling and how "wide" the bars are. I hope I explained my problem clearly. I'm an experienced developer, but completely new to MASON and Multi-Agent simulation. -T
