Enclose each property name in quotes. For example, plot ('ShowOrientation',true To plot the graph of a function, you need to take the following steps − Define x, by specifying the range of values for the variable x, for which the function is to be plotted Define the function, y = f (x) Call the plot command, as plot (x, y The code I use for plotting the points the second time is: figure () for i=1:1000 %1000 is the length of x_vector and y_vector. plot (x_vector (i), y_vector (i), 'o') hold on. axis ( [0 1920 0 1080]); set (gca, 'ydir', 'reverse', 'xaxislocation', 'top') end. And this is the result of the previous code Try This Example. View MATLAB Command. Create a scatter plot and vary the circle color. x = linspace (0,3*pi,200); y = cos (x) + rand (1,200); c = linspace (1,10,length (x)); scatter (x,y, [],c) Corresponding elements in x, y, and c determine the location and color of each circle

You cannot use strings as x coordinates in plot(). You can use integers instead and set the axis xtick positions to the integers and set the xticklabels to the strings. You might also be able to plot using a categorical() as the x axis T his is a short tutorial that documents how to make a MATLAB plot on top of an image background. This can be useful for a variety of things but when I first learned about it, I was a bit confused by how the axes seem to be flipped sometimes when you do this. In this tutorial I will give several examples that should illustrate how to plot on top of an image properly. I have used this technique.

  2. 1) If your discretization : x=0:0.05:2; do contain the intersection point, you can use the intersect function in Matlab. For example. intersect([1,2,3],[4,3,1]) will return a vector with two elements 1 and 3, the intersection of those two vectors. To find the intersection point is to find the point x such that y1(x)=y2(x). So apply . yin.
  3. Just like it is to change the color of your plot in Matlab, the same goes for changing the line style, increasing the thickness of the line or some other aspect of it .

For example, I may want some data points drawn in the same color as the curve. Or I have a piece-wise graph that I want to have all the same color. There are several ways to do this. One is to use the default colors and resetting the order, which is shown here. Others involve using the RGB triplet (see next section). x=linspace(-10,10); y=3*sin(x); xp=[0:pi/2:10]; yp=3*sin(xp); x1 = linspace. Plot Point ist ein von Syd Field in die Drehbuchlehre eingeführter Begriff.

First you have to interpolate x depending on y. Next, you have to do the interpolation separately for each of the discontinuous segments. Since the function has discontinuities after every 5 data points, we don't have to figure out the discontinuities but interpolated every set of 5 points separately (the xi_end, yi_end denote the last data point of the previous segment to plot the horizontal. MATLAB actually plots the points (x(i), y(i)) joined by straight line segments. This becomes obvious if you do not use enough sample points when plotting a smooth function. Plot the function y = sin(2 pi x) for x in the interval [0, 1] using 11 points. Create a vector x of 11 equally spaced points in [0, 1]. Create a vector y of function values. Plot the points, producing the figure below. This is a question that I've seen at various times, both in MATLAB Answers and in MATLAB Newsgroup. The question is in regards to the fact that when MATLAB puts markers on a line plot, it puts them on every data point.
