How to plot a line onto a vector field?Hello. I'm doing line integrals and I wanted to plot my paths onto the vector field from (0.0) to (4.2).
This is what I did to create the vector field.
with(plots):
fieldplot( [1*y, 2*x], x=0..5, y=0..3, arrows = slim);
Now I want to plot these paths below ONTO my vector field.
plot( x^(1/2), x=0..4 );
plot( 1/2*x, x=0..4 );
plot( 1/8*x^2, x=0..4);
How to I merge these lines onto the vector field instead of having separate plots?
Thanks in advance.

vectorfield plotHi, I have a unit vector of three components,
Rx=Sin[p]*Cos[q];
Ry=Sin[p]*Sin[q];
Rz=Cos[p];
where, p=(Pi/2)*(1z);
and q=p*Cot[p];
I want to plot the vectorfield of this unit vector in the region, {z,
0,1} and {q,0,0.5}
Nilaakash,
Your question is not very clear. Actually you aren't asking anything
but are only making a statement ;)
You seem to want to plot a 3D vector field and you have given equation
for their direction. However, you should also provide information
about their *position* and you haven't done that.
You're talking about a region given by...
plot a vector fieldHi, are there anybody who tried to write a function to plot 3d vector field?
I know quiver3 command can do this. But I want to know if there is any
function that can take symbolic expression as input. For example, given a
vector field F= [2*x, sin(y), x+z], where x y and z are symbols, a function
like this plotvectorfield(F,[xmin,xmax,ymin,ymax,zmin,zmax]) will plot the
field lines. Did anybody try this? Thanks.
A 3d automatic field line plotting routine is sorely needed, but I have
only found a 2D version, fieldlines.m at the file exchange. If you find
a 3d version, let me know....
How to plot field lines ?Hello, I'm new here.
I have some complicated deformed dipolar magnetic field in cartesian components, and I need to show some field lines. I'll also have to extract coordinates of lines to a list. How should I do that ?
I can use the code below (with properly defined functions fx, fy and fz), but it's unreliable (it frequently hit the singularity at the center) and it frequently gives many unpredictable curves. Any idea ? Please, I need help ! :(
FieldCurve = NDSolve[{
x'[t] == fx[ x[t], y[t], z[t] ],
y'[t] == fy[ x[t], y[t], z[t] ],
z'[t] == fz[ x[...
plot field linesI want to plot TE and TM modes in rectangular waveguides. Actually lines of electric and magnetic field. I want that the density of lines to be proportional to the intensity of the fields. I tried the command contour but it plots the intensity as a function of color.

plot vector fieldHi, I have an easy question for a gnuplot expert.
I have in output from a fortran program a vector field (magnetic
field) defined in every point of space. The code is not a grid, but my
output is a file with 6 columns at every line: the coordinate XYZ and
the values of Bx, By, Bz. How can I plot in gnuplot the field lines?
Thanks a lot!!!

Plotting constant field linesHello,
I have 2 questions related to an equation for a magnetic field vector,
B, from a dipole in cylindrical coordinates:
B = (u0*m/4*Pi*r^3)* {2 Cos[theta] , Sin[theta]}
where the first index is the r component and the second is the theta
component.
First, how do I use VectorPlot to plot this in cylindrical
coordinates?
Second, without using any higher end built in Mathematica functions,
How do I get Mathematica to plot field lines of constant Magnetic
field strength? I'm using PolarPlot, but coming up short.

quiver plot a vector fieldI am trying to plot a 2d vectorfield; and though it is not yet
working, it seems close:
fieldcoef=[13 13; 13 12] ;
x = [1:.2:1]; y = [1:.2:1] ;
[xgrid ygrid]=meshgrid(x,y) ;
% values=fieldcoef*[x;y] ; % Not proper syntax
xy=[x;y]
values=fieldcoef*(xy) ;
quiver(xy(: 1),xy(: 2),xgrid,ygrid) ;

??? quiver(xy(: 1),xy(: 2),xgrid,ygrid) ;

Error: Unexpected MATLAB expression.
Any suggestions?

plotting a vector field in 3dHi,
I am trying to plot a vector field in 3d and i have great difficulty in doing so.
I have 3 variable, bx,by,bz that have (nx,ny,nz) dimentions which represent the vector field.
My questions are:
1) How can i plot this vector field. I have tryied a variety of things (flow3 etc) i found online but all advices seems to lack some part of information and i fail to reproduce the results.
I also whould like a hint on how i could overplot those lines above an xy image on the bottom of the plot.
2) Is there a way to trace the field lines and have, lets say 3 variables of dimentions (nlin...

The `with vectors` plotting style applies only to 2D plots in gnuplot

Yes. 3D vector fields were added to the development source tree
in Sep 2004. Download the current version from SourceForge.

Plotting Vector Fields in Mathematica 7Hello,
In Mathematica 6, there seems to be no way to specify the size of the
arrow heads used by FlotVectorField. Therefore I resorted to the
following workaround:
Graphics[{
Arrowheads[0.02],
VectorFieldPlot[..][[1,3]] }]
but this depends on the internal structure of the graphics object
returned by VectorFieldPlot and is therefore likely to cause trouble.
Is this still required in Mathematica 7?
Best,
Nikolaus

How to plot the magnetic field vector along the trajectoryDear all,
I have the magnetic field data and spacecraft position data.
I want to plot the magnetic field vector along the trajectory.
I think I should first plot the spacecraft trajectory, and then plot
the magnetic field vector along the trajectory.
But I do not know which procedure in IDL can perform the second step.
Is there anyone who can can help me?

how can I plot field lines similar to contour?I haven't been able to find a nice solution, so...
How can I plot field lines from 3D vector data in a way similar to what
contour does for 2D data? With contour, you can pick the number of
contour lines you want and even the levels at which to plot them.
However, there seems to be no similar way to plot field lines.
I found a simple but effective 2D solution at the file exchange:

Is there something similar in 3D?

plotting streamlines / vector fields for systems of ODEHi there,
I would like to plot streamlines and/or vector fields for systems of
several odes, by which I mean systems of 3D or more and plots of 2D
or 3D.
I have been able to use routines like quiver, quiver3, streamslice,
streamline, and coneplot, with varying degrees of success, for 2D and
3D systems... the matlab examples always look a lot work better than
my systems!
Now I have some 4D and 5D systems for which I would like to simulate
some trajectories and plot a series of 2D plots for selected pairs of
the variables. I know how to plot several trajectories by selecting
initial condition...
How do I set vector fields using userinput?Hi guys,
I'm new to scheme programming and encountered problems assigning user
input values to vectors.
My program flow is as follows:
1. Prompt user to specify how many fields in a vector
eg: if user key 3, the vector shall have 3 fields.
2. Prompt user to input values into the 3 fields
I tried using :
(vectorset! 4AUVector 0 '(read))
4AUVector is my vector name, 0 is the 1st field, and (read) is the
userinput, but I got..
vectorset!: expects type <mutable vector> as 1st argument, given:
#(0 ,1 ,2); other arguments were: 0 (read)

read from a file and plot a 3d vector field.....
Hello:
I would like to read a vector field form a file and plot
it in three dimensions. The file format is :
n x y z v_x v_y v_z
where n is the data number, x, y, and z are the Cartesian
coordinates and v_x, v_y, and v_z the components of the
vector field.
I was wondering if something like this can be plotted with
maple 9. I couldn't find any hint in the manual apart from
the fieldplot3d which seems to work with procedures or
analytical expressions.
Thanking you in advance for any help

List plotting a vector field containing invalid dataI'm solving a 2D CFD problem, which is generating a lot of colocated 2D
velocity field data, using a regular rectangular grid. Some of the grid is
masked out, representing ocean bottom topography.
Is there a relatively simple way to modify ListPlotVectorField to ignore the
masked out values (which are stored as as unphysically large values, but this
is easily modified)
Thanks.
Gareth,
Why don't you use the second form of ListPlotVectorField?
"ListPlotVectorField[{{pt,vec},{pt,vec},...}] displays a list of vectors,
each based at the corresponding point."...
experimental animated von Koch field line plot...The following is one of the experiments I am working on wrt exposing von

Nicer vector field plot, arrows should all start on the gridHi,
I'm using Maple 10 on Linux and I am not satisfied with the behaviour of
fieldplot.
One little example:
with(plots):
feld := vector([sin(y),0,0]);
fieldplot3d(feld,x=1..1,y=0..2*Pi,z=1..1,grid=[5,15,5],arrows=THICK);
If you rotate the plot, so you look on the top you should see what I
mean. The arrows don't start on the grid. It's more like that the middle
of each arrow is on the grid.
Is there an easy way to fieldplot a vector field so that the endings of
the arrows are all on the grid?
Thanks in advance,
Sebastian.
