I need to analyze my speed by scrolling my mouse over the line on the chart. However, when my mouse cursor gets close to the top of the window, the "smoothing" dropdown box appears and obscures the data I need to look at. See the attached image that will explain this better than words! The same thing happens on my other bike with a power meter but in that case, the power curve is at the top where I don't want it.

I don't seem to have anyway of re-ordering the curves. If I could put a curve that I don't need to run my cursor over, eg. slope or gear ratio (I am on a fixed gear track bike) on top, then it would not be a problem.
Any other suggestions?
Thanks very much.
Mike
