Simple Read of Chart Values

Postby blahfunk » Wed Jan 17, 2018 6:08 pm

I am hoping there is a better way to get tooltip values of data in a linegraph. To hover over a point can be difficult if there aren't a ton of points. I have another program we use in the office that just draws a line where your mouse pointer is and shows the tooltips for all graph lines that intersect with that line. Is there a similar feature in JFreeChart and if not would anyone have a suggestion on how to implement such a feature?

Several alternatives are examined here, including using (larger) shapes and/or a ChartMouseListener.
