I have recently setup a HighStock column bar graph and have noticed some strange behaviour with the scrollbar while zooming.
I have the buttons setup to show zoom at the 2year, 3year and 4 year level. Whent he user uses the scrollbar (and say positions it at the far left) then tries to zoom in, nothing happens. If the user then moves the scrollbar back to the right and clicks the zoom it zooms in as expected.
Is this standard functionality? or can the scrollbar be set to expand the opposite way after it passes the halfway point?
You can actually see this "feature" on the frontpage of the highcharts site. the highstocks example at the top right. Scroll the bar all the way to the left then try and zoom in on a year.
