Is it possible to synchronize dygraphs with other charts using same timestamps?

For example my raw data has the following columns: [timestamps, speed, latitude, longitutde] and I use dygraphs to generate a speed over timestamps chart. Somehow on the same page I'd like to generate the geographic track using the latitude & longtitude coordinates with another charting lib (not sure exactly which one yet).

Is it then possible to make the two charts synchronized? If so, how?

The expectation is when the mouse hover on a certain speed data point, the corresponding timestamp is returned and can be used in some mechanism to mark the corresponding location point on the whole geographic track. And vice versa.

FWIW, timestamps have unique values.

Yes, it is. You want to specify the highlightCallback and unhighlightCallback options. They get called when the user mouses over the chart and then mouses off it. Check out this demo to see when they fire. The second parameter to the highlightCallback function is your timestamp.
