Maximum zoom-in limit

I am using dynamic zooming in my plot, but I want to make it more user-friendly.
I wanted to implement limits, so user cannot zoom-out too far and zoom-in too close.
Limiting zoom-out is quite simple - i just set absolutemin/absolutemax values, and it works.
As far as i know, there is no out-of-the-box feature that would work similarly but for zoom-in.
Actually, I am out of ideas - i tried disabling zooming after the length of axis was too short, but after this I am not able to zoom-out again (AxisChanged event is not called anymore).

Do You guys have any ideas how I can limit zooming-in?

Should we add a "MinimumRange" property to the axes? With default value double.MinValue..

Sounds promising!

Thank You, how could I miss it? It works exactly as it should :)

Maximum range meaning between the visible min and max points? 'cause that sounds like a pretty decent way of limiting it (also as wbidus mentioned MinimumRange already exists =P). I've said this a few times already but it'd also be nice if the AxisChanged event had more information in it's event args (like factor or new screen points).

Yes, it should be the minimum between minimum and maximum. Sorry, I forgot that it was already implemented. And default value should of course be 0...
@Slxe: I think we can start a new discussion/issue on changing the AxisChanged event data. I am a bit hesitant to exposing more data than what is absolutely needed :-)
