Plot Lines on a Map?

[#1]

Hi

I have been able to successfully implement Lat/Lon coordinates based on my data. I would now like to plot lines in between the points based on the great circle.

So I would like to connect the three points above with a line showing the flight path of an aircraft, therefore it should use the great circle to use the shortest line between the two points.

Would I need to create an extension for that? I successfully created these lines on a webpage, but how do I do it within Qlikview?

Thanks for your help.
