More 3-d plot questions [message #992] Wed, 14 April 1993 07:20

Hello again,

I have another question about 3-d plotting. How do I get a logarithmic
Z-axis? There is no /ZTYPE keyword for either the SURFACE or AXIS routines. I
tried two approaches:

!z.type = 1 & surface, Z & !z.type = 0 ; doesn't work at all.
; or
surface, alog10(Z), zstyle = 5 ; don't plot Z axis
!z.type = 1 ; set to log Z axis
axis, zaxis = 1, zstyle = 1 ; plot the log Z axis
!z.type = 0 ; set to linear Z axis

The second approach works, but has some bugs. For example, when the log(Z)
range < 1, I get only one tick marked. Is there a better way?

I also still need answers to my earlier questions:

1) How do I plot a series of 2-d plots, vertically oriented and positioned
along the Z axis?
2) For any 3-d plot, how do I get annotation to come out on the X-Z plane?
