I got two problems creating a 3d-plot. First, as the title mentions, I want to cut out a distinct interval from my 3d-Plot.

For example when the graph is displayd from -y_max to y_max but I just want it to be shown from -y_max to -5 and from 5 to y_max again.

I also got a second question:

Another thing I want to do with this graph is redefining this axis with a parameter which is directly dependant from it.

Like for example I want to redefine the "y" axis with a" k" axis with k=y*2, so that in the end I have th

Dear all,

I would like to find a way to make the reflection of a spherical wave inside a tube (a cylinder). You have herafter an exemple of a sphere increasing inside a tube, but without the reflections...


Any idea how to do this?

Thanks a lot for your help.


Hi all,


I am generating a sphere with increasing radius that interacts at some point with a plan, just like this:

I would like to find a way to make the sphere "wave" (I agree this is not a wave...) reflected by the plan as in a mirror.

How could I do that ?

Thanks a lot for your help.


Is there an elegant way to plot in 3d only the portion of the function f(x,y)=sqrt(25-x^2-y^2) for which 9 <= x^2+y^2 <= 16 ? I'm looking for a nice plot that shows it against the whole sphere with radius 5, so that it's clear which part of the sphere is cut out.

Hi all,

I have a 3D graph and when I right click on the surface, under style, I can see the option of contour. When I click on that I can see some contour associated with the surface. I want maple to show the values for each contour when I observe it from the top . I want to copy and paste some surfaces in a same figure and campare the contours.


Thank you




A quick question, Can I add legends to 3D plots? 


I have studied most posts about plot quality, still confused.


When I export 2d graphs and import the to microsoft word, the quality is horrible. How can I presents my results in a reseanably good way? 

what command should I add to my code that the quality increase notoceably? 

Any suggestion about 3d plots? 

If I export as an eps file, how can I import that in microsoft word? I did, but I guess they are not compatibble. 


thank you 



I am trying to find the interpolation of a 3D function.

I have the vector x, the vector y and a matrix M at my disposition.
I know how to do the pointplot3d , but I can not find the function: f(x,y) 

any suggestion?


Thank you for help


I am trying to plot 3d scattered data as a 2d scatterplot with the third dimension being displayed as colour or a line that separates the value of the two functions (for example, the higher value and lower value at that point). I attached the file. I have two functions and several parameters that are constant. Here, I want to use P[A] on the x-axis, and P[B] on the y-axis. The z dimension is the profit functions, either Profit[1] or Profit [2]. I want to show them in colors like the highest one is red and the lower one is green, or something similar.  P[A] and P[B] are probability values and P[B] is between 0 to 0.50 with 0.01 increments, while P[A] is always less than P[B]. The file is here:


P[A] := 0 ..P[B]-0.01

P[B] := 0 ..0.50

Anyone please help me to code this problem.Thanks,


Suppose that we have the following curve on a unit sphere




which is the implicit equation of a circle in "cylindrical coorinates" (r,phi,z) on the sphere.

How can I plot this curve without solving the implicit equation for r or z ?

Also, I don't want to make any parameterization.

hello guys,


i have a system of autonomous equations which i want to plot its 3D phase space with directional field,

i have some problem with it , and i dont know how to command for add some directional field for 3D phase space .


thank you guys


I would like to plot a 2D contour plot in the botton of a 3D plot of a spacial curve. I don't know how to do that in maple, but I found something similar done in Matlab for a 2Dcontour plot in the botton of a 3D surface.

Can someone help me?



Hi All,

I would like to create a 3D plot or surface plot and got stuck here and need your help.

I have a text file cretaed from C++ program. This file contains data in 8 columns. The first columns are X and Y values and rest of the columns are my calculated values based on X and Y. How can I visualize column numbers 3 to 8 based on X and Y values? Here is a sample:

0.00 0.00 0.378629 0.043703 0.259182 0.221199 0.181269 0.139292

I defined a line normally, but when I try plot this line in R3, appears a shape of a plane.

How can I plot only a line in a 3D window?

Line has coordinates x,y, e z.


Dear Maple users

I am delighted that Maple has builtin commands to plot so many polyhedrons in 3D. Here I am talking about the polyhedraplot command in the plots package. I was however disappointed that the socalled Truncated Icosahedron is not supported (not present in the supported list ...). My first question is:

1. Why isn't it supported?

It seems more relevant than many of the other polyhedrons which are supported. It is a member of the Archimedian Solids (see Besides it is the basic structure for soccer footballs. I found out that a TruncatedIcosahedron command is available in the geom3d package. This command is able to deliver data for the faces and more. With this command I succeded in writing a small program to actually plot this polyhedron in 3D:



    local i::integer,
    for i from 1 to 32 do
    end do;
end proc:



Since I am not really experienced in programming in Maple, here is my last question:

2. Can I simplify something in my code above?


Best wishes,
