  Subject: [Visualpython-users] Clarifying question regarding semi-log plots


  In my earlier (9/11/08) "submit" I asked:
      "How can one "fool" Vpython  to display y=f(log10(x))  as a semi-log plot?"

  To clarify: 
      How can I change the "tick-marks" to a log scale?

  see sample program below:

  ************************

  from visual import *
  from visual.graph import *


  graph1=gdisplay(x=0,y=0, width=400,height=300,title="semilog",xtitle="f=10^x",
                  ytitle="y",xmax=4,xmin=1,ymax=500,ymin=0,
                  foreground=color.black,background=color.white)
  plot1 = gvbars(delta=0.5, color=color.green)

  x=[10,100,1000]
  y=[400,200,100]

  for i in range(0,3):
      plot1.plot(pos=(log10(x[i]),y[i]))
