This might not be a maple question. But I know maple has very smart and many plotting tools as well as this comunity is full of very skillfull people. So I concluded that I might get an answer here.

Lets say I got some sphere that is cut off by any abirutary plane, how would I go about plotting this?

For the purpose of this example the sphere is centred at the origin with radius of 4 and are cut of by the plane z=2-y.


I am trying to graph an olique cone with a circular base, and I am having trouble learning how to generate an equation for it. Any help is greatly appreciated!


When I m working on my laptop the plots wont show as it would on my stationnary machine. The surfaces is smooth without any grid and spacecurves dont display at all.


I have tried to uninstall and install maple without sucsess. This is maple 2016


I want to plot the eigenvalues of a 4x4 matrix. I know how to determine the eigenvalues, but how do i plot them? Because i saw that plot only works with real numbers. The result is a column vector. 


I'm currently using Maple 17 and I'm trying to programatically export .eps 3D plots using the following code:

plotsetup(eps, plotoutput = `square_of_x`, plotoptions = `color=rgb , portrait, noborder, height=4in,width=4in, shrinkby=0.1`)

The problem that I'm facing is:

1- The z-axis label is outside of my figure (see uploaded figure). This happens even if I try to save the figure in .png and it seems that the 'shrinkby' option its not working properly;

Could you help me solving this?



For the PDE, I can't seem to plot T' as the y-axis, it gives me the error, "Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct". Anyone knows what seem to be the problem? I am open to all ideas and would appreciate any help:)

i need to find the graph of exp(v(r)) from 0 to 2e6.

i obtained the graph of v(r) by taking log but how to obtained in exp form


I apologise if this information is available on the support pages or on these forums already.

I have found the general solution to a differential equation and now need to plot multiple solution curves that correspond to a different value of a constant.

For example if I had y(x) = x + k, how would I go about plotting this for all the different values of k.

Many Thanks. 



G := 6.6743*10^(-8); 1; R := 1336599.126346; 1; rho := 2.2450*10^14; 1; c := 2.9799*10^10; 1; a := 1/(8/3*(6.67*10^(-8)*Pi*rho/c^2))^.5











y(x) = rho*c((1-(x/a)^2)^(1/2)-(1-(R/a)^2)^(1/2))^2/(3*(1-(R/a)^2)^(1/2)-(1-(x/a)^2)^(1/2))

y(x) = 0.1993516000e36/(3*(1-0.8033593953e-1*Pi^1.0)^(1/2)-(1-0.4496840993e-13*x^2*Pi^1.0)^(1/2))

I want to have a display() function that plots a certain expression that I already have defined, but then I also want to include a variable number of pointplots into the same graph. I basically want the user to define a set of x and y coordinates into two different arrays in the start of the Maple Worksheet, then later down the worksheet, I want to plot these x,y coordinates as a pointplot, for each point.

But for example, if there are 5 points, I would define the pointplots as p1,p2,p3,p4,p5, which I already have a loop to do automatically depending on however many points that has been defined in the previous arrays. But when I want to plot these in a display() function, I have to write display(p1,p2,p3,p4,p5) individually, and I can't therefore seem to find a way to make it like display(p1,...,pn). I want the display to add more pointplots depending on how many points are defined in the arrays.

Can anyone help me? Sorry if it was difficult to understand, I can explain further if you didn't understand.


I am trying to write my Measuring Data into several Arrays with lengt of rowdim

I was able to extract them from the Datafile and Refering them to separate Vectors

My Code is in the attachemend and the Datafile too.

Insert the txt Path in the Messdaten in definition of A to load it.

I was able to convert the Time from Seconds to Minutes. What i realy want is an x-Axis wich is like hh:mm:ss

and Plot for Example T__1,T__2,T__Scheibe together in one Plot as y Axis and t__Minuten as x Axis

But the


doesnt work and i also tried others

Thank you for your Help



In maple you can use the interactive menu and choose what axes you want to look at the plot, ie. I choose Z axes and see the plot from above, can i do this by using syntax as a plot option?

here is my homework, i am new to maple and need some help!

Consider the logistic equation:

dP/dt = 3/100 * (P(M - P)),

with seasonally varying population constraint

M(t) = 20 + 1.54sin(pi t / 6)

use maple to plot the solution curve for P(0) = 25


I'm trying to plot several periods of this 2π-periodic function f (x) = 3x, x ∈]-π; π] with the following code which I got from an older post.

However, when using uneven multipla of PI as x it just gives me a verticle line. Can anyone shed some light to this or perhaps give a better solution?

Thanks in advance

Best regards




Hello everyone,

The problem resides in the argument "l" (small l) in the function "ratio", more precisely in the function "expi" then "riskexpjs" then in "ratio", so after try-outs I noticed that, then maple couldn't execute the function plot as decribed in the script.

Best regards,
