PlottingHi,
I am trying to plot a series of randomly generated line segments. However for some weird reason the following code is not plotting all of them. For example, if I were to set the num variable to 3, it only shows either 1 or 2 lines. If i set it to 6, it only displays 4 lines... I'm lost!! If you need more parts of my code please let me know. Thanks.
for i = 1:num
if (i == 1)
axis([0 film_length 0 film_length]);
hold all;
end
X{i} = originX(i,1):0.1:endX(i,1);
Y{i} = slope(i,1) * X{i} + intercept(i,1);
p = plot(X{i},Y{i});
if (type...
Plot and PlotsHi everyone,
I am trying to produce a graphic showing continent outlines,
coastlines etc, with a graticule and the footprint of a satellite
image. I can do all this by using MAP_SET, and then I use PLOTS to
plot a vector of the image coordinates. Using MAP_SET however, I can
only specify a STEREOGRAPHIC projection, when I want a POLAR
STEREOGRAPHIC projection.
To get a POLAR STEREOGRAPHIC projection I need to use MAP_PROJ_INIT
and then PLOT to display the graticule. However when I do this I cant
seem to get PLOTS to display the image footprint. I have converted my
image footprint coordinates...
plot in plot?Hi, I've a problem with the plot respectively imagescfunction. I
want to diplay a sketch in the same figure displayed by imagesc.
The problem is that the sketch does not consist of full matrix, it
are just a lot of points that have to be plotted. The points are
simply represented by one x& yvalue pair. By now i can display it
only using a forfunction and plot point by point  what needs a lot
of time.
Another approach was to change the linestyle of the plot and use
markers, but if choose the marker '.' the sketch gets to large
points.
Is there a way that "plot" d...
How do you plot multiple plots in an array with no space between plots?I have some data that I'd like to plot in 12 small square plots, and then arrange those 12 plots into a 4x3 rectangular array. The thing I'd like to do that I don't know how to do is simplify the 4x3 rectangular array by squeezing the plots together, such that there is no space between the plots: the righthand border of a plot should be coincident with the lefthand border of the plot to its right, and its lower border should be coincident with the upper border of the plot right below it. Imagine 12 squares on a checkerboard; that's what I'm aiming for.
As far as I ca...
PLOTS and the new PLOTHi all,
Can anyone tell me how the new PLOT() handles scalars/1element arrays
for X and Y? Or do you still have to use PLOTS?
If you have a graphic created with PLOT(/buffer), will a subsequent
call to PLOTS go on the right plot? Or will it try to go in a window?
Thanks!
Gray

plotting implicit plot.hi mans..
i need to plot a circumference so i need to plot in implicit form..
such as x^2+y^25x2=0..
so how can i do??
i find also this topic
http://www.mathworks.com/matlabcentral/newsreader/view_thread/21684
but it doesn't help me much..
i also tryed this:
plot(plot::Implicit2d(x^2+y^21, x = 1..1, y = 1..1))
and matlab find an error..

??? plot(plot::Implicit2d(x^2+y^21, x = 1..1, y = 1..1))

Plotting density plotsHi,
I am looking for a free application running on windows able to display 2D
sets of data (like a matrice) as a density plot (plotting values assumed at

Gnuplot for instance, does not have this feature implemented.

If you want one plot to remain while putting another one down, use the HOLD command:

Plot contour plots on 2D planes of 3D plotHi,
I am trying to plot 3 contour plots (2D) on the three planes

Any idea how to do it?

Labeled Plot not a Plot?My latest hassle arises, so far as I can tell, from doing the following:
myPlot = <An ordinary plot>;
myLabeledPlot = Labeled[myPlot, "\nMy label string\n", {{Top,Left}}];
Print[myLabeled Plot];
Export["my_labeled_plot.pdf", myLabeledPlot];
and then importing my_labeled_plot.pdf into a Tex source file using
pdftex.
The output of the Print[myLabeledPlot] looks fine: just what I want, and
all in one cell.
But when the exported my_labeled_plot.pdf file is either viewed in the
TeX'd file or just opened in Acrobat, the label strin...

Creating a plot with line plot and scatter plot in the same figureHello,
I am looking to plot a line plot of a function (say, x^2)

Perhaps it involves using the "hold on" command?
Thanks so much for your time!

How to save a specific plot as image and then use that image to plot into 3d plot.I would like to know if there is any way to plot image
(jpeg,tiff,bmp) on axis plot.
I am currently doing a 3D volume (6 surfaces) plotting function which
involves very large data set (more than 100MB worth of file size).
The data will create 6 surfaces; top,bottom,left,right,front,back.
While I can load the volume cube (using surf), rotating or zooming
in/out really slows down/sometimes hangs the graph.
I understand it happens because of the amount of data it needs to
process over every rotation. My question is, are there any way to
save each of the surfaces as images. This is so I can repl...
Plot a series of lines on another plot, holding only the current line on top of the other plot.Hi
I'm trying to plot a series of lines within a loop on another plot, so that only the current loops line shows up on the old plot, whilst holding the old plot as it is.
for i=1:endpoint
for j=1:endtime
plot3([0 XL1(i,j)],[0 YL1(i,j)],[0 ZL1(i,j)],'LineWidth',2);
plot3([XL1(i,j) XL1(i,j)+XL2(i,j)],[YL1(i,j) YL1(i,j)+YL2(i,j)],[ZL1(i,j) ZL1(i,j)+ZL2(i,j)],'LineWidth',2);
pause(0.1)
end
end
thats the plot i want added to the old figure, but if i add 'hold off', it removes the previous plot.
How do i fix this?

Of course, the colour of the lines has to be distinguishable from the co...
Hiding a plot and saving the plotHi all!
I'm having this need to save a plot as jpg file.
i know that i can use the command below:
saveas(gcf, 'C:\BP_201204_001.jpg');
however, before that i would need to create the plot say
plot(0:20000, result);
i would like to plot the 'result' without displaying the plot to
screen, thereafter saving the plot using saveas function.
is there any command which i can use that i have not yet found? can
any kind soul help me out?

Plotting multiple plots on the same graphUsually when I want to plot two sets of data on a single graph, I use plot (x1, y1, x2, y2) or the plot, hold on, plot, hold off method. This works great. I recently began using lots of weibull fits and even with these wblplot, hold on, wblplot, hold off worked just as well. The problem I am having comes when I begin to censor data for Weibull fits.
I can use probplot('weibull', Y, cens, freq) to do censoring very well and I can do this many times but I now have a set of data that has three different zones where I would like to plot the one set of data and the 3 weibull fits for th...

I didn't see anyone try to answer this. I have to confess I don't kow what
you mean by "category." The ecdf function does return vectors that you can

Which maple command are you using to generate the surface plot, and what
