问题
I am currently using JFreeChart scatter graph to display a number of points. When I use the scatter graph to draw lines it draws them in the wrong order for example: the ordered list (2,3),(2,5),(3,4) is the desired order to be printed. JFreeChart takes this and draws the line in this order (2,5),(2,3),(3,4). Is there an alternative chart type I could use that could display this differently or is there a way I can override their default ordering system? Thanks.
回答1:
An XYSeries is typically used to create a scatter plot's data set. It includes constructors that exert control over the sorting. There's a related example here.
回答2:
create XYSeries with autoSort flag set to false
