how to change BASELINEINTERCEPT value to faciliate plotting on log scale: LAYOUT OVERLAY3D

[Varrelle]

Dear SAS community:

log gives the following error:

NOTE: The log axis cannot support zero or negative values for the axis from plot data or
due to default or assigned BASELINEINTERCEPT value. The axis type will be changed
to LINEAR.

I would like to plot z-axis on log scale. How can I fix this? None of my data points = 0.  Please see my embedded code for context.

Thanks.

data _3dtest;
x=1; y=1; z=5; output;
x=2; y=1; z=3; output;
x=1; y=2; z=2; output;
x=2; y=2; z=1; output;
run;

proc print data=_3dtest;
run;

proc template;
define statgraph _test_3d;
begingraph;
entrytitle 'Testing z-axis on log scale';
layout overlay3d/cube=false 
zaxisopts=(griddisplay=on type=log
logopts=(base=10 tickintervalstyle=logexpand)) rotate=130;
bihistogram3dparm x=x y=y z=z;
endlayout;
endgraph;
end;
run;

proc sgrender template=_test_3d data=_3dtest; run;

I looked a bit closer at the documentation -- it appears that log axes are not permissible for this plot type.

Does anyone know of a work around?

Thanks
