#### plotting vertical lines

```Hi,
Maybe someone can help me.
I have a signal that i divide it by frames (have a matrix of frames) - now I want to plot the entire signal but at the limit of each frame I want to insert a vertical line, that will show the frames limits.

How could I insert those vertical lines in my plot?

Thanx
```

```I've used the stem() function.  I think you could also use the line()
function.  Just supply the endpoints of the line.

```Hi ImageAnalyst,

I don't understant how I can plot the line between the frames, with the function 'line'.
In my code I have a matrix of 56x441, which each row is a frame. I use the function 'reshape' to add all the frames and to plot the entire signals. But between each frame I want to insert the line that demostrate the limit of frame.

Could you explain yourself or if there's another way also great.

Thanxs

help plot log[f[t]] vs a parameter using an ODE
I've solved the following equation for y[t]. eqn = y'[t] == a (y[t]/((y[t])^2 + b )) - c y[t] + d keqn = eqn /. {a -> 10 , d -> 0.1 , c -> 1 , b -> 10 } ksol = NDSolve[{keqn, y[0] == 0}, y, {t, 0, 200}] Plot[y[t] /. ksol, {t, 0, 200}, PlotRange -> All]; Now I would like to plot the log of y[t] while varying a over a range of values ( 0-40) How will I accomplish this? It seems like I would have to solve the DE while varying a a little at a time then take the log of it? At first I thought the following will do the trick, but it didn't. I was tr...

Partner Plus 206 module lines continuously ring.
Folks, We have a Partner Plus R3.1 system installed here. Last week, one of the 206 expansion cards stopped working. Lines 5&6, as well as the extensions attached to the 206 card worked intermittently, and would drop in the middle of calls. Accordingly, we purchased another expansion card (206E R3.1). Removed the old card, put in the new card. The extensions now work fine, however, lines 5&6 are not functioning correctly. Symptoms: When line 5 is plugged in, it will start ringing on all the extensions, when the line is picked up, it hangs up immediately. When the extens...

Plotting
Hi, 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...

I know the Order subplot(1,1,1); subplot('Position',[3 3 100 20]); plot(f,MX); but it does not work :( he always takes the dimensions from 1,1,1 oder 2,1,2 or so... but not the position??

Hi, I use plot(x_axis, OriginalData); hold all; for trial=1:1000 f = getData(...); plot(x_acis, f); end The different f-functions are all concentrated around "OriginalData" (more or less randomly with some variance). I want to plot now the "envelope" as well as a "density" plot, i.e. where most of the instances lie.

2 Voice Lines in a Cat5 Env
Does the following work? I have two phones in room A. I run a cord from Phone 1 and Phone 2 into a 2 line/1 line splitter. I then plug the splitter into a RJ45 patch panel.

Probability scale plot
Hi, there, Is it possible to set the y axis of plot figure to probability scale? I need to plot some grain-size data, of which the y axis (accumulated percentage) should be in probability scale and the x axis (size) should be in linear scale. Thanks in advance. I don't understand exactly what you want. The built-in axis scales in MATLAB are linear and log. There's a "normplot" function in the Statistics Toolbox that creates a plot on which the y tick marks have labels between 0 and 1 and are spaced according to the quantiles of a normal distribution.

plot with different ranges
I want a fit function to be plotted only in a special range: plot [x=0:400] 'Data.txt' using 1:2, [x=100:400] f(x) however seems not to work. Is this somehow possible ? If not, then this could mean that I would have to use another tool, simply because I can not print a fitfuntion in the whole graph because that would mean that the fit is relevant in the whole plot which is not true.

Re: Selecting the right error for split-plot repeated measures
I'll pare this down to the statement: "I have tried proc mixed instead but I don't like the output it provides." Because PROC MIXED is ideal for a split plot analysis with covariates (and GLM most definitely is not, unless you make multiple runs), I wonder if maybe we couldn't generate the output you are looking for somehow. Could you say what you don't like? As far as what you have, it appears to be "correct" in the sense that the proper error terms are being used to test effects. I would expect separate p values for your dependent variables, as you have ...

surf plot boundaries
Hello, I'm using surf() to plot a 20x20 matrix. Surf() correctly shows a 20x20 grid in the resulting plot, but the lower X and Y bounds are 0. Since matlab arrays start with element index number '1' and not '0', the lower row/column are empty in the plot. Also, the last row/column of data is lost, even if I change in axis bounds (from 0:20 to 1:21). I know I can fix this error by padding the matrix with one row and column of zeros, but I assume I'm missing something here that would make it easier. Does anyone know how to address this issue? Am I making a mistak...

Process X values in Parametric plot
Hi all, its been a while... I am writing some ocean scripts to work out sensitivity of various specifications to design variables. What I would like to do is to process the X values so I can show them in % terms rather than the absolute value set for the design variable being changed. For example, say I am varying a width of a device, and plotting ac- gain. The normal result from the parametric simulation would be a graph of the width on the x axis against the ac-gain on the y axis. However, I want to show the % change from the mean value of the width on the x axis and the % change from the ...

centering the image plot EXACTLY?
Whenever I plot something using PLOT, the figure is never exactly centered due to the numbers on the left hand side and on the bottom taking up a bit of space and thus displacing the image by that amount. How can I get the image to be EXACTLY centered? I don't need the number info or tick marks or border at all and just want an exactly centered image on the page, but even when I set AXIS to OFF the image is still not centered and acts as if the numbers were still there. ...
