Folks,
CurrentPoint returns a value that is not a timedate format. I do not know how to handle this. I did a Google search, but could not find the answer. I would like my ButtonDown callback to be able to return a timedate value corresponding to the x-axis:
cPt = app.UIAxesRaw.CurrentPoint(1, 1:2);
But it returns a value around 0.95 always.
Thanks for your help!

Because all of the data are returned in one array any datetime values are converted into a numeric equivalent (i.e. to provide one homogenous array). You could use DATETIME to convert the relevant x-value back to a DATETIME object, but the easier and more general approach is to use NUM2RULER:

cPt = app.UIAxesRaw.CurrentPoint(1,1:2)
xDt = num2ruler(cPt(1),app.UIAxesRaw.XAxis)
