Multiple Graphs in Maple

Jbone12115 — Sat, 19 May 2012 05:30:03 Z

I have an equation that is a function of two variables i.e Cp(beta,lambda). I have to plot several Cp curves on the same graph for a range of lambda=0..15 (x-axis). The 1st curve I want Cp@beta=0, 2nd curve Cp@beta=5, 3rdcurve Cp@beta=10 .... and so on

How can I do this without having to define a separate Cp equation for each beta value?

plotsetup and if statements

ce5 — Fri, 18 May 2012 13:48:08 Z

Hello

I have Problem with the Maple command plotsetup, it does not seem to work within an if-statement.

What i would like to do is this:

1. Make a matrix with 0 or 1 as enteries

2. convert this matrix into a list where the 1's are points. (So the Matrix entery Matrix[1][1]:=1 would give the listvector:=[1,1]

3. plot these vectors as graphs and store them with the help of plotsetup

4. changing the matrix and rinse and repet 2,3,4 until satisfied

deplot3d graphing question

scamuicune — Sun, 22 Apr 2012 15:42:54 Z

Hello! I am trying to graph the following:

dx/dt = -10*x + 10*y
dy/dt = r*x - y - x*z
dz/dt = -(8/3)*z + x*y

where x, y, and z are all functions of time (t). Solve the equations subject to the constraint that r = 25 and the initial conditions that at t = 0, x = -1, y = -1, and z = 1.

This is my code:
DE*plot3d({d*x(t)/dt = -10*x(t...

Plotting question (Maple 15)

Mac Dude — Tue, 03 Apr 2012 17:00:31 Z

I have a data set that represents some parameters at different locations in a (linear) system. The way the data are organized is as 1-d vectors which in turn are combined into an Array. I.e. Array[1] is the first vector; Array[2] the second and so on. Each vector represents a data subset, all subsets are against a common independent variable, call it Knob. I plot one of these subsets like this:

plot(knob,vector[1],style=point);

That works fine & I can replace...

How to i solve a ploynomial and trig function equation

tosynero — Tue, 03 Apr 2012 09:11:34 Z

c:=12+10x^4+7x^3-89x^2+65x+4sinx

how do i plot a graph of c,

calculate the roots and check the correctness of all found roots.

Thanks for your kind solutions in advance.

Mechanics. Trajectory Plot

Chrissieh18 — Sat, 31 Mar 2012 15:45:34 Z

I am fairly new to Maple and trying to understand the dsolve command for numerical solutions and plotting graphs of radial distances and trajectory plots.

This is my code below. All of it successfully brings up a solution apart from the very last command and I don't understand why it is not working.

I believe the last plot is plotting a trajectory plot but I am not sure. I am meant to use the solution to plot the trajectory plot (X(t),Y9t))=(r(t...

Diagramm: Fit a function one some measured points --> exponential function

Xilyte — Wed, 14 Mar 2012 10:31:45 Z

HI,

I measured some points. This points are plotted in a graph. Now I want to make a fit on this points.

I now that the fit-function has to be like this:

F = A + B1 x e^(-t/C1) + B2 x e^(-t/C2)

Problem: how can I create a fitting function like that?

The best thing I found is the "spline"-fit, but it doesn't work properly. It has to be one lonely function, not a summary of several functions (like spline).

Maple freezes whenever I try to plot

hellisforheroes659 — Sat, 25 Feb 2012 13:29:20 Z

Hi,

Im not sure if anyone can help but whenever I plot a graph maple freezes. It looks like the program just refuses to plot it and repeats the command until i get to past where the graph should be at which time it goes back to working fine.

Another way of describing the error is, whenever i...

Error plotting Contour Plots

Chrissieh18 — Mon, 20 Feb 2012 16:44:28 Z

I inputted the folllowing into Maple.

with(plots):
contourplot(x^2*y/(x^4+y^2),x=-1/2..1/2,numpoints=60^2,color=blue);

However it is giving me this error:

Error, (in plot/iplot2d/expression) bad range arguments x = -1/2 .. 1/2, numpoints = 3600

I don't understnad why.

Plotting options

Carlo Carminati — Fri, 17 Feb 2012 08:07:56 Z

A very useful feature of the plotting program gnuplot is that you can generate an output which is a file instead of a graph. For instance the following short script

################
f(x)=sin(x)+cos(pi*x)
set samples 5000
set table "outfile.dat"
plot [0:10][] f(x)
################

produces a file containing a sampling of the function f(x) on the interval [0,10] based on a grid...

Multiple plots in the same box

soechristian — Wed, 08 Feb 2012 17:20:09 Z

Dear Mapleprimes,

I need to plot a graph for different values of a specific parameter, sigma. It would be great if I could plot them in two separate coordinate systems right next to each other, such that I can copy paste them into my article. Could anyone help me with that?

Cheers,

Removing vertical lines for non-linear plots

soechristian — Wed, 08 Feb 2012 16:01:52 Z

Dear Mapleprimes,

I have a problem with a graph. I need to plot the following:

plot({1/(1-x)}, x=0..2, y=0..4);

But I don't want the vertical line at x=1. How do I get rid of it?

Cheers,

Christian

Remove plot structure

icegood — Wed, 25 Jan 2012 12:43:47 Z

There is a cool option of dropping one graph from multigraph (after that it goes as separated one). How to get this dropped structure itself? I.e. i have "graph" component with command AllPlots that itself is

AllPlots:=plots[display](AllPlotsStructure,...);

AllPlotsStructure is a list of plot/textplot.

After all i removed one structure by drag-and-drop on component. How to update AllPlotsStructure correctly?

Arrowed labels in graph

icegood — Tue, 24 Jan 2012 17:56:32 Z

Need to do in maple smth like that:

how do i plot multiple plots in a graph?

kristen — Tue, 20 Dec 2011 08:20:16 Z

i am plotting multiple plots in one graph using the following commands. This has been successful for a different function but it doesnt work at all for the typed function. can you pinpoint my mistake? maple sheet is attached as well.
