Basically we could end up in a situation where the plotInfo is no longer valid, yet the model changes and triggers a redraw before the new data is passed into the TankBar. Instead of chasing that race condition it seemed much easier to just copy the plot_data entries and the gas information in the dive. Fixes #716 Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
