Hi,

I improved on the panning feature. It no longer has a 'zoom' side-effect
associated with it. The endonTick and startonTick options were causing
problems and rounding the axis min/max to nearest tick I suppose. I also
added a custom reset zoom functionality, it is very similar to the inbuilt
'Reset Zoom'. Whenever we call the setExtremes() method the link is
displayed and is kept hidden in the original display settings(zoomRatio = 1,
no Pan).
