How do you plot data points?

How do you plot data points?

Follow these simple steps:

1. First, find the value for x on the x-axis.
2. Next, find the y-value – in this case, y=1100, so find 1100 on the y-axis.
3. Your point should be plotted at the intersection of x=0 and y=1100.
4. Finally, plot the point on your graph at the appropriate spot.

Can you plot a matrix in Matlab?

plotmatrix( X , Y ) creates a matrix of subaxes containing scatter plots of the columns of X against the columns of Y . If X is p-by-n and Y is p-by-m, then plotmatrix produces an n-by-m matrix of subaxes.

How do you highlight a point in Matlab plot?

Direct link to this answer

1. a = fspecial(‘gaussian’, [100 1],0.9); % Gaussian distriubution.
2. plot(a); % you will see Gaussian curve. Now I want to highlight the maximum value.
3. [y x] = max(a);
4. hold on; % hold the plot for other curves.
5. plot(x,y,’o’,’MarkerSize’,10);

How do you show data points on a Matlab plot?

Create a line plot with 1,000 data points, add asterisks markers, and control the marker positions using the MarkerIndices property. Set the property to the indices of the data points where you want to display markers. Display a marker every tenth data point, starting with the first data point.

What is plotting of data?

A plot is a graphical technique for representing a data set, usually as a graph showing the relationship between two or more variables. The plot can be drawn by hand or by a mechanical or electronic plotter. Graphs can also be used to read off the value of an unknown variable plotted as a function of a known one.

How do you plot a matrix on a graph in Matlab?

In MATLAB®, you can use the bucky function to generate the graph of the geodesic dome.

1. [B,V] = bucky; G = graph(B); p = plot(G); axis equal.
2. % Define a matrix A.
3. spy(A(1:30,1:30)) title(‘Top Left Corner of Bucky Ball Adjacency Matrix’)
4. spy(A) title(‘Bucky Ball Adjacency Matrix’)

How do I plot data points in MATLAB?

Enter into the command window “plot(x, y, “.”) to plot the points. The “.” in the code places a “.” at each coordinate of the x-y matrix. For instance, a point will be placed at (1,2) and (2,4). Step. Click on the “Show Plot Tools and Dock Figure” in the figure menu to change the marker type.

How do I plot a line in MATLAB?

How to Plot a Solid Line in MATLAB. 1. Clear all active variables within the workspace by entering ‘clear all’ in the Command window. 2. Create data to plot. Input ‘x=1:1:50’ and ‘y=rand(1,50)’ into the Command window.

How do you create a graph in MATLAB?

Steps Know a few things about MATLAB. Open MATLAB. Create a new Function file. Set up your Function file. Set up your data. Now set up your graph. Make sure the final line in your function file is “end” and save your file. Execute the function. View the results.

What is the plot of a graph?

A plot is a graphical technique for representing a data set, usually as a graph showing the relationship between two or more variables. The plot can be drawn by hand or by a mechanical or electronic plotter .
