DateTimes are represented with ticks equal to 100 nanoseconds– But using a DateTimeAxis I cannot plot points down to this level.
It appears that the axis is converting to doubles behind the scenes and thus loses the precision that a DateTime has. When zoomed in the chart pan and zoom has erratic behavior (freezing and not responding in what appears to be a non-systematic way).
I’ve attached a simple solution that reproduces the unexpected behavior.
