[ROOT] Setting range for graphs

Dear Rooters

I have some questions regarding graphs:

1, When I draw a 2-dim graph, I would like to set the axis range for
both x- and y-axis. However, I am only able to set the range for y:
   TCanvas *vC1 = new TCanvas("vC1","Graph example",200,10,700,700);
   TGraph *vGraph = new TGraph(num,x,y);
   vGraph->SetMinimum(2);
   vGraph->SetMaximum(7);
Do you know, how I can set the range for the x-axis?

2, What does function Smooth do?
The following seems to have no effect:
      vGraph->Smooth(num,x,y,2);  //num > 10000
      vGraph->Draw("AP");
How do I use Smooth?
What does the parameter "drawtype" do?

Thank you in advance for your help.
My system: PowerBook LinuxPPC 2000, root 3.01/02

Best regards
Christian
