EEG Monitor does not work properly with multiple inputs of different lengths.

For example if you use 3 arrays, lengths 1000, 100, 100 and u select some channels from all of them.

If 1000 is first one, you will see all data but the vertical line will not work as expected, data remains in 0-500 interval.
If 100 is the first one, you will only see 100 points of data and the rest of the 900 will be ignored.
