How to make a surface plot
tsubame
Sorry for the basic questions, but I am a beginner of IGOR Pro (Ver.6).
I want to make a surface plot of mathematical function, like z=f(x,y),
and each variables have domain of definition, respectively.
(ex. 0 < x < pi, 0 < y < 10...)
I cannot obtain the plot what I want to do.
Could you please help me ?
Firstly, I'm in big trouble I don't know how to make a matrix.
Now I'm trying to make a Wave which is corresponding to "z", by the command below
"Make/O/N=(20,20) w2D; w2D = ... "
Please tell me if I'm wrong.
And I'm using the tool named "Gizmo", and this is quite-complex for me.
So, I want to know the basic way of making the plot mentioned above, or about the basic operation procedure of "Gizmo".
Regards,
That's a good start. I recommend looking at the Getting Started manual. View it by executing this command on Igor's command line:
DisplayHelpTopic "Getting Started"
Be sure to keep going- the Guided Tour that's part of Getting Started will help you understand how Igor "thinks".
This won't cover two-dimensional issues, however. You may want to review Wave Assignments:
DisplayHelpTopic "Waveform Arithmetic and Assignment"
and issues having to do with multidimensional waves:
DisplayHelpTopic "Multidimensional Waves"
To establish the X and Y ranges of your function, use Igor's wave scaling. You can use the Change Wave Scaling dialog (in the Data menu) or use the SetScale command on the command line:
SetScale/I x 0,pi,w2D
SetScale/I y 0,10,w2D
Then use a two-dimensional wave assignment to fill in the Z values:
w2D = ...expression involving X and Y...

The easiest way to get acquainted with Gizmo is to watch the video tutorials here: http://www.wavemetrics.net/tutorials/gizmo/

Roughly I could obtain the plot what I want to make.
Thanks,
