Items tagged with axes


I tried to generate a simple plot based on an expression using units. Please see the screenshot of the worksheet below

The y-axis should be scaled in m3 not m2 because a, b and the variable r are in m. I know that it is possible to enforce the axis scaling in units using useunits but since the mathematical definition of the expression is clear this should not be necessary.

The other question is why is the y-axis missing the variable name? On this page on the Online Help it is mentioned "When you plot an expression, the axes labeling shows the variable names and units." I think what I am plotting is an expression.


Dear All

I have simple problem related to ploting of 2-D graph

What I need is listed as below:

1. How I can re-scale axes by 1/2.

2. How to give custom gap between graph and its title.

3. How to place two legends in vertical format in opposite to horizontal.

4. How to assigne custom gap between legends and graph

5. How to place label 'q[b]' on the right side of vertical axes.

f[1] := 0.6553e-2+0.61277e-1*cos(.9976156575*x)-0.3448e-2*cos(1.995231315*x)+0.164e-3*cos(2.992846972*x)



f[2] := 0.6601e-2+0.61212e-1*cos(.9878156204*x)-0.3834e-2*cos(1.975631241*x)+0.182e-3*cos(2.963446861*x)



plot([diff(f[1], x), diff(f[2], x)], x = -3.2 .. 3.2, color = ["Red", "Green"], linestyle = [solid, dash], legend = ["undistorted ( n=0.0, q=0.0)", "undistorted"], labels = [tau*``, q[b]*`\` `], labeldirections = [HORIZONTAL, VERTICAL], size = [500, "golden"], title = "Radial velocity curve of Polytropic Model of Index N=3", titlefont = ["ROMAN", 15], legendstyle = [font = ["HELVETICA", 9], location = bottom]);





Hope somebody can help me! I installed Maple on my computer, but everything is very small , for example the bar in the top with all the small icons. It is the same thing when I make plots. The values on the axes are very small. How can I change this?

I have taken a photo of the problem, don't know if it helps.

How can I link the axes in two or more separate plots so that when I zoom in one, the others are also zoomed. Also when I want to link the 'x' or the 'y' axis only.

Thank you

Consider a plot generaged by:

export_plot_options:=font=[TIMES, roman, 30], axis=[thickness=4, location=low], size=[850,850]:
points := [seq([seq(exp(-(x^2+y^2)*(1/100)), x = -10.0 .. 10.0)], y = -10.0 .. 10.0)]:
plots:-listdensityplot(points, export_plot_options);

How can one get rid of white space between the axes and the actual data??


Hi,I'm using Maple 15. When I plot with the command

Aplot:= Plot2D(Q[2 .. 26, 13], Q[2 .. 26, 14], style = point, color = blue, symbol = solidcircle, symbolsize = 16, font = [Arial, Bold, 13], axes = box, axis = [thickness = 1, tickmarks = [5, subticks = 5]]);

There is the report of problem

Error, (in plot/options2d) unexpected axis suboption: thickness = 1

Thank you for helping me.


Hello everyone!

I used Maple 17 to fit an ellipse to a set of points using the following guide:

My rotated ellipse was calculated to be:


0.3939708949 x^2 - 0.005975799853 + 0.6345432059 y^2

But everytime I try to graph it in Maple 17, it only shows the axes and nothing else. Any help would be extremely appreciated.


I am trying to make a three dimensional cube in maple by using matrices. I also have to make it rotate about the x,y,z axes, project it with three different origins, and translate it (I'm assuming this means translate it across an axis?). I have already made the cube, but when I try to rotate it across one of the axes by multiplying my matrix by one of the rotation matrices (this is what I put un maple: P1:= matrix([[1,0,0,0],[0,cos(theta),-sin(theta),0],[0,sin(theta),cos(theta),0...

Just a small digression.  It would be nice if the numbers on the x-axis could be rotated or angled so it does not look like they collide with each other.  When the numbers reach the 100's or 1000's there will be congestion. 

This is perhaps a suggestion for a future Maple version as the current versions do not support number rotations on the axis.

It is possible to thicken the axes of 2D plots by adjusting the underlying data structure, since the appropriately placed THICKNESS() call within the PLOT() data structure is recognized by the Standard GUI. This does not seem to be recognized for PLOT3D structures, however.

The issue of obtaining thicker axes for 2D plots can then be resolved by first creating a plot, and then subsequently modifying the PLOT structure.

The same techniques could be used to thin...

How to solve this problem in maple?
Decide which of three lines given are tangent to the graph of f(x) at given points.
The function to define is f(x)=2x^3-4x^2+3x-5
The possible tangent lines are:
y = x - 5
y = 2x - 5
y = 3x - 5

1. What is/are the zero(es) for this function? In other words, what is the solution for f(x)= 0

2.  What axes values (x- and y- ranges) are appropriate for this graph?

3. When plotting each linear function with f(x...


I would like to set the range for a 3d plot.  For a 2d plot, I understand I can do it at the command line or by setting the axes properties after the plot's been drawn.

If I use plot3d(x*y, x=-10..10, y=-10..10) for example, how can I look at those parts of the surface for which -2 < xy < 2 for example?  I'd be happier with a command line option than a gui option but really anything would do.


many thanks!


Is there a way to make the x, y and z axes thicker in 3d plots?


I am missing two options in the "fieldplot3d" command, which I am using in cylindrical coordinates: one is "style=contour" and the other is "axes=cylindrical" where apparently only the "axes=boxed" option as available.
Any ideas how I can get this?

Or can I show a polar plane at one end of the cylinder? like in the post:

this is my plot:


I am getting bcak into MAPLE after being away for a while, so this might be a trivial question, but...

I am using plots[pointplot] to plot a series of points.  The default min and max values on the x and y axes of the plot are the corresponding min and max values of the x(first) coordinates and y(second) coordinates of the points.  I can change this by left-clicking on the plot and adjusting the axes properties, but I am wondering if it would be possible...
