Zoom issue (want to zoom only VTOL back tranzition)

[MartinStokelj]

I am using FlightPlot v.0.3.2 (flightplot.jar) and when I zoom the graph disapears
ulog example is on link

when I zoom only at back tranzition time

I’ve seen this a lot where zooming makes everything disappear. It seems (not definitively) to be correlated to the version of Java you’re running.
