I have some 2D points and I want to plot them in MATLAB such that every point has a different color and specifier. I have used plot function but it creates line whatever you give https://in.mathworks.com/matlabcentral/answers/451953-how-to-plot-points-without-line#answer_421431. Cancel. Copy to Clipboard. Sets the line style as none, and select a marker as you like. For example: plot (x, y,'linestyle','none','marker','o') Sign in to answer this question line(x,y) plots a line in the current axes using the data in vectors x and y. If either x or y , or both are matrices, then line draws multiple lines. Unlike the plot function, line adds the line to the current axes without deleting other graphics objects or resetting axes properties View MATLAB Command. Create vectors xt, yt, and zt. t = 0:pi/500:40*pi; xt = (3 + cos (sqrt (32)*t)).*cos (t); yt = sin (sqrt (32) * t); zt = (3 + cos (sqrt (32)*t)).*sin (t); Plot the data, and use the axis equal command to space the tick units equally along each axis. Then specify the labels for each axis The symbols can appear in any order. You do not need to specify all three characteristics (line style, marker, and color). For example, if you omit the line style and specify the marker, then the plot shows only the marker and no line. Example: '--or' is a red dashed line with circle marker

MATLAB Plot Colors, Line Type, and Marker Type . The MATLAB plot() function can actually take an additional third input that tells it what color, what type of line, and what type of marker (dot on each point) to use. This input is given in the form of a string (enclosed in single quotation marks) that can contain up to three letters/symbols. These correspond to the color, line type, and. plots data in the x and y vectors by connecting each pair of points with a red dashed line. The third argument of the plot command is a one, two or three character string of the form 'cs', where 'c' is a single character indicating the color and 's' is a one or two character string indicating the type of symbol or line. The color selection is optional. Allowable color and symbols types are. Line style, marker, and color, specified as a character vector or string containing symbols. The symbols can appear in any order. You do not need to specify all three characteristics (line style, marker, and color). For example, if you omit the line style and specify the marker, then the plot shows only the marker and no line https://la.mathworks.com/matlabcentral/answers/251801-plot-points-without-connect-it#comment_319478 Cancel Copy to Clipboard scatter() creates a single graphics handle

Plot linear regression without data points. Learn more about scatter plot, linear regressio equation as a line on the data plot, and display the equation and goodness-of-fit statistic on the graph. MATLAB Features: data analysis Command Action polyfit(x,y,N) finds linear, least-squares coefficients for polynomial equation of degree N that is best fit to the (x,y) data set. graphics commands Command Action plot(x,y,symbol) creates a pop up window that displays the (x,y) data points.

Don't create variable names like this in the first place. As you can tell, it becomes hard to work with them downstream in your code. Instead, rewrite your code to produce a single variable named x that has all of the 'x' values, and another variable called y for the 'y' values This will plot a line graph with all the points marked in a circle format, which is usually known as circle markers. If we specify no line in the command, then the output will be in the form of markers only, without displaying any line which is required to connect the points. Example #2. a = linspace (0,5,10); b= a*2+sin(2*a); plot (a, b,'o.

plot(x(10),y(10), 'r*') % marking the 10th data point of x and y Alternatively, starting in R2016b, you can specify the MarkerIndices property to plot a line with marke r s at specific data points . For example, plot a line with a marker at the 10 th data point 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. With line type '-o', the MATLAB plot command plots six 'o's at the six data points and draws straight lines between the points. So I added the title plip because this is a graph of the piecewise linear interpolating polynomial. There is a different linear function between each pair of points. Since we want the function to go through the data points, that is interpolate the data, and since two. View MATLAB Command. Plot the sine function over three different ranges using different line styles, colors, and markers. figure t = 0:pi/20:2*pi; plot (t,sin (t), '-.r*' ) hold on plot (t,sin (t-pi/2), '--mo' ) plot (t,sin (t-pi), ':bs' ) hold off

### 3-D point or line plot - MATLAB plot3 - MathWork

Plot Multiple Lines. By default, MATLAB clears the figure before each plotting command. Use the figure command to open a new figure window. You can plot multiple lines using the hold on command. Until you use hold off or close the window, all plots appear in the current figure window. figure x = linspace(0,2*pi,100); y = sin(x); plot(x,y) hold on y2 = cos(x); plot(x,y2) hold off. Change Line. 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(x(k),y(k)); So, how can we get the data points(x,y) laying within distance of 0.5 in both directions x and y from the inside wall along the boundary. In other words, How can I get data points(x,y) that is (0.5 or less) away from the inside of the boundary wall in any direction (x,y) How to plot a contourf without the lines.
