#MATLAB PLOT UPDATE#
Here the values will be plotted using a logarithmic scale for x and a logarithmic scale for y.If what you want is for the plot to "grow" point by point: the easiest way is to create an empty plot and then update its XData and YData properties at each iteration: h = plot(NaN,NaN) %// initiallize plot. plot( X, Y ) creates a 2-D line plot of the data in Y versus the corresponding values in X.

When the loglog command is implemented both axes will switch to a logarithmic scale.
#MATLAB PLOT PDF#
For example, if we want to plot two variables on. The steps to create a PDF file with multiple plots are listed below: First, import the PdfPages class from and initialize it to an empty PDF file. The function that we were asked to plot is the following: 1 x(2)/9 - y(2)/4.

Furthermore it doesn't look anything like the example we were given for reference.
#MATLAB PLOT CODE#
The figure command is used to initialize a figure. My Matlab is a little rusty, and I don't think that I quite got the code right. To solve this problem, we have to use the figure command. plot(G,LineSpec) sets the line style, marker symbol, and color.For example, plot(G,'-or') uses red circles for the nodes and red lines for the edges. In Matlab, if we plot a variable and after that, we plot another variable, the second variable will overwrite the first variable. Here the values will be plotted using a linear scale for x and a logarithmic scale for y.Ī plot using a linear scale for y and a logarithmic scale for x Plot Multiple Plots Using the figure Command in MATLAB. When the semilog command is implemented, depending on which axis is specified, one axis will remain on a linear scale while the other axis will switch to a logarithmic scale. This table classifies and illustrates the common graphics functions. Notice in this example we used a different way to get the domain for x,y using linspace as opposed to the above example. There are various functions that you can use to plot data in MATLAB.
#MATLAB PLOT HOW TO#
This example demonstrates how to plot more than one graph on the same figure. > hist(variable, 3) The addition of the number after the variable in the command tells MATLAB how many bins there are to be in the histogram. mesh(x,y,z) zlim(-2,2) xlabel('x'),ylabel('y'),zlabel('z') title('3D Plot Example') Multiple 3D Surfaces. Ten is the default number of bins and will always be used unless otherwise indicated. > hist(variable) This command creates a histogram with ten bins (cells). If > plot (x,y) had been used instead, Matlab would have plotted y vs. The plot command can also be used with just one input vector. This does an x-y scatter plot with an 'o' marking each point. MATLAB can plot a 1 x n vector versus an n x 1 vector, or a 1 x n vector versus a 2 x n matrix (you will generate two lines), as long as n is the same for both vectors. x on one graph > plot (x,y,'*',x,z,':') Plots y vs. > title ('whatever you want') Titles the graph (put anything you want inside of apostrophes) > xlabel ('the x-axis label') Labels the x-axis > ylabel ('the y-axis label') Labels the y-axis > grid Superimposes grid onto a graph > axis () Sets axis ranges > x= creates data set x = 1,5,8,3,10,7,3 > y = creates data set 'y' > plot (x,y,x,z) Plot y vs. Here is a list of some of the commands you will need for plotting graphs in Mathlab.
