I have an XYLineChart in JFree and I have a graph. I want to show the values of lineChart with popup at any point of the line. I did some research about this subject but I couldn't find something to do. How can I do that? Photos are attached below.
This one is which I have. Cyan crossline shows where my mouse is.
This one is which I want to get. This popup is shown when I move the mouse on the curve.
