Dear All,
I've been having difficulty with this one. All the examples refer to making a meshgrid with x, y , then those last two gets mapped onto the function z(x,y)
however I want to do something totally different. I'd like to plot each function
1st Axis X: 1st function g(t,u) where t on [0 : tstep: 10] , u = [-10: ustep : 10] ;
% do we just do a meshgrid for those two ranges first off?
2nd Axis Y: 2nd function log10(g(t,u)) for log defined on [-1 :logstep: 1]
3rd Axis Z: time progression t from [0 : tstep: 10]
I need to study the function g(t,u) in respect of its Log10 as time progresses, hopefully it would make more sense with the following pseudo code:
define g(t,u) on [-10:gstep:10] , t on [0 : tstep: 10] , u = [-10: ustep : 10] ;
define log10(g(t,u)) on [-1 :logstep: 1]
define t on [0 : tstep: 10]
plot3D ( g(t,u) , log10(g(t,u)) , t) ; % that's the Target End Result

view would be helpful, thank you.
However that does not help in visualizing the relationship between g(t,u) & log10(g(t,u)) ( with t)

The relationship between g(t,u) and log10(g(t,u)) is log10.
You could create two plots, one log10 and the other not log.
If you want to plot log10(g) and g as if they are two independent variables, then you will need to explain how you want to collapse all of the differences caused by u onto a single axes. For example, is it acceptable to plot t, max(g(t,u) over u), log10(max(g(t,u) over u)) -- a "maximum intensity projection" ?
