How to get values ​​by cursor coordinates in JFreeChart?

Question

Java

Hello. How to get values ​​of all graphs by cursor coordinates? The chart uses TimeSeries . The y

- axis is the values ​​to get, the x -axis is the time. The orange arrow is the cursor. When you click on the field with the mouse, you need to get all the values ​​from all series at the time point indicated by the red line (X axis); In Google codes, I found the following example of obtaining coordinates on a chart: analisbursatil.googlecode.com/svn/trunk/AppletGr... I can't apply this to determine the current item in series. I can get a list of series, but I can't get the desired value that would correspond to the cursor position.
In theory, it can be torn out of the XYDataset (I did this for tooltips), but what values ​​should be substituted there? :/
