Mathematica Problems

  1. Aug 3, 2006 #1
    I have searched the Mathematica bible long and hard and done various searches in the help index of Mathematica but have found nowhere instructions on how to solve my problem.

    For a 2D, or in my case 3D plot, you choose the x and y axes easily by setting them in the initial command to plot your function, but there does not seem to be anyway to choose the z axis limits? I am reasonably confident Mathematica is chopping off most of my function and I want to extend the z axis up to higher limits to observe the full plot. Has anyone else experienced this problem?

    What you are probebly looking for is the PlotRange option. You should use it like this:

    Code (Text):
    Also becouse the default setting of PlotRange is Automatic and it usualy work preaty well, it might be a good idea to reconsieder your x and y renges (make them smaller if you don't REALLY need them that big).

    Hope this helped.

    PS: This thread might be more sutible for the Computers/Programming forum.

    Well, I could be wrong, but in the case of the 2D case all you do is use the tag PlotRange->{min,max} as an option. So for 3D I would use the same option and change the PlotRange.

    It would look something like:
    Plot3D[function, {x,xmin,xmax}, {y,ymin,ymax}, PlotRange->{zmin,zmax}]

    Give it a try. There is also a listserve for Mathematica. Send a message asking to be added to it at: mathgroup@smc.vnet.net

    Let me know if that works or not.

    Seems LENIN is quicker than I.

    Well, it seems LENIN and I agree atleast. So it should work.

    Thank-you, this was very helpful and correcetd my problem. I can't fathom why Mathematica insisted on plotting just bizarre z-axes by default but I have now a nice plot of the correct function.
