## How to change range on Contour Plot?...

Hi,
I don't understand how contourplot chooses it's view range. I would like a contour plot to go from r=0..10 and display axes from [-10..10, -10..10].

plots:-contourplot(r*sin(phi), r = 0 .. 10, phi = 0 .. Pi, coords = spherical, grid = [80, 80]);

doesn't produce a plot with range [-10..10]. Adding view doesnt compute anything differeently, just makes the axes bigger.plots:-

contourplot(r*sin(phi), r = 0 .. 10, phi = 0 .. Pi, coords = spherical, grid = [80, 80], view=[-10..10,-10..10]);

I want more contour lines near the endpoints of the range. why is it focused in the middle?

any help is appreciated,

Thanks!

## Automatic Plot Ranges...

I'm doing an interactive component and i need to plot a function and some points (which can change).
My question is if is it possible display the graphic with a value of automatic Plot Ranges.
For example the graphic would started with the first point and finisched with the last, like in this image (but i did it manually).

I want a sort of autozoom.

## Combine multiple views in 3D animation...

Dear all,

My script has multiple animations, in which the range of the variable is larger then I wish to see. Therefore, I have used the view=[x1..x2,y1..y2] command, which has different values for every plot. Plotted seperately, this gives me exactly what I want. However, if I combine the plots using display(A,B,C) they loose their individual views. Instead, maple chooses the view of plot A, and plots B an C in the range defined by view A.

Is there a way to combine plots and still maintain individual views, within the largest view?

Kind regards,

## How do I make a point on a chart move as I drag a ...

I wote a command that creates a plot with a single point:

plots[pointplot](a*[1, 1])

Before hitting Enter I called the context menu and chose Explore. As I change the parameter a the point remains fixed in the picture but the scales change. I wanted the opposite: the scales should stay fixed and the point should move. How can I do this using Explore or in some other way? I would like to see the point move as I drag a slider control.

Thanks for the help.

## Plot size and number of ticks...

My question is related to changing the plot size and modifying the number of ticks.

For example, I am plotting y vs. x, and x is from -1.0*Pi/2..1.0*Pi/2. I want to modify the plot size with size=[h,w]. If I have three ticks in x-axis if I change to small width, then the number of ticks is decreased. How can I force it to have the certain number of ticks? Also, why if I set view=[-1.0*Pi/2..1.0*Pi/2,0..1] then the -1.0*Pi/2 disappear if the width size is small.

Thanks,

## Extracting View from Several Plots...

I have several plots generated with geometry objects:

plt1 := draw(...); plt2 := draw(...)

I want to display all them with a reasonable window.  I have been looping and and using a rather dumb proc to find the window size. I use the view=[...] option with the values calculated to set the plot view.

I wanted to post the proc, but, really messed that up!  I will try the proc later.

Some of the plots I am working with have views like

> for itm in [relBrgLinePlot,relTgtPositPlot,relTgtLinePlot] do
op(-1,itm);
end do;
VIEW(0. .. 95., -61.58179461 .. 16.)
VIEW(5.48225506 .. 95., -61.58179461 .. 16.)
VIEW(5.48225506 .. 95., -61.58179461 .. 16.)

> for itm in [geoSensPositPlot,geoSensLinePlot,\
geoBrgLinePlot,geoTgtPositPlot,geoTgtLinePLot] do
op(-1,itm);
end do;
VIEW(0. .. 35.35331852, 0. .. 87.13244438)
VIEW(0. .. 35.35331852, 0. .. 87.13244438)
VIEW(0. .. 95., 0. .. 87.13244438)
VIEW(40.83557358 .. 95., 16. .. 25.55064977)
VIEW(40.83557358 .. 95., 16. .. 25.55064977)

Is there an easier way to do this?

## How to color point plot?...

Hi all,

I was wondering if it is possible to add a colour gradient to a point plot to represent another perameter in the data.

For example, each point corresponds to a value of 'f' ranging from 0.1 to 1, and I was wondering how to display this by means of a colour gradient.

Thanks,

## Problem with "atomic variables"...

I have some preferences for viewing. Specially, I prefer atomic variables to be showed with a different color. So I check mark the related option for this in the view menu. But every time I close and reopen the Maple, it just restore my setting for atomic variables. Suprisingly, this does not happen for other viewing options in the view menu! What should I do? Why is it like this?

## Why are ranges exceeded?...

eq1 := z = y*log(x): eq2 := z = y+x*log(x):

DispIntersecting := implicitplot3d([eq1, eq2], x = 0 .. 10, y = -30 .. 30, z = -40 .. 40, color = [blue, green]):

solve({eq1, eq2}, [x, y, z]);

assign(%):

DispIntersection := spacecurve([x, y, z], x = 0.1e-2 .. 10, color = red, view = [0 .. 10, -30 .. 30, -40 .. 40]):

display(DispIntersecting, DispIntersection, axes = boxed, scaling = constrained);

## Visible circle, also below 3D graph?...

Hi all,

How can the black circle be visible?

Visible also below the 3D graph?

Best, perr7

B := spacecurve( [R*cos(t),R*sin(t),0] ,t=0..4*Pi,thickness=1, style=line, color=black);

animate( plot3d, [     P_Pi2(x,y,t)  ,  x=-4000..4000,y=-4000..4000 ], t=0..1, frames=10, transparency=0, style=surfacewireframe, labelfont=[times, roman, 25], orientation=[45,60,0], view=[-4000..4000, -4000..4000, 0..0.006], caption=typeset( theta=Pi/2 ) , axesfont=[times, 15], axes=frame, background=B   );

## Plotting a Surface by plot3d...

Why maple is not plotting the whole surface in the domain specified?

Thanks for the help.

## Need to restrict range on a graph...

Hello,

I have a procedure which plots a graph. I need the x-axes, which in this case is theta, to range between -3 and +3. However, I am not sure as to how I can create this restricted range. Any help is greatly appreciated! Thank you in advance!

Kind regards,
