Axis minimal and maximal zoom constraint

Hi,

Am trying to limit the depth in which the user can zoom into and out of the graph. I came across the property minimalZoomConstrain in the header file and also the documentation and had attempted to use it.

The axis in question is a DateTimeAxis and I would want to limit the zoom in depth to 30 seconds and the zoom out the about 3 months. I understand that the type it takes is the GenericType, where I will have to use the SCIGeneric(x) to assign the value, but what value x am I required to use in this case?

I’ve tried the values ’30′(assuming it takes NSTimeInterval) and even attempted to pass in a NSDate value but nothing seems to work.

Thank you.
