Hello,
I'm working on charts with dynamic multidatasets (timeseries). I needed to see tool tip containing all the values with a single date, of course, better on separate lines, so I made some modifications to TimeSeriesToolTipGenerator.
Now the problem I have is when the data gets added to the chart and the oldest set is deleted the ToolTipGenerator throws an exception (XYDataset .getYValue(int,int)).
I've tried to "fix" it by comparing series id with the number of series,etc. - no luck.
Could you please advise what should be done to implement the desired behavior. Chart/ToolTipGenerator/exception are below.
Thank you very much!
