Extract Min and Max values from Contour Plot

Hello,

I have a special function that creates a contour plot on the surface of cylinder. I would like to extract the minimum and maximum values from my contour plot because I would like to restrict the min and max values of other plots I make later to match ones from the first one for comparison purposes. Is there any way I could do this easily?

You can access the ContourMatrix property of the contour plot if you are using R2014b or later. You can then use a routine such as c2xyz from the File Exchange to expand it into coordinates. You can then max() and min() as appropriate.
