Matlab multiple plots are used to shows the data in different ways such as Line Plots, Discrete Data Plots, and many more. In most cases, when you use name-value pairs, you must specify the labels in a cell array, such as legend({'label1','label2'},'FontSize',14).. Use the Legend object. Imagesc function is used to show the data into array D as a figure by using the full span of colors in the color map. I found the max height and min height for both plots but i've been trying to figure out how to plot on the graph the max point and min point. e.g: get (gca,'xlim') will give you the limits of the x axes of the current axes. When the file is executed, MATLAB reads the commands and executes them exactly as it would if you had typed each command sequentially at the MATLAB Command Window. Holding legend on a Matlab plot inside a loop. The plot function is used to plot sets of data on a 2-D grid. In some application, there is a need to save the output figure file to do farther operations like data reading, data analysis from an output file, to reference the output figure file. You can switch back and forth between the figures as necessary by issuing the same . The reason you get an image with size 419*560 is because you are setting the axes to fit the figure in this line MATLAB by default assigns the plot to the latest figure object created. SAVEAS is an inbuilt function available on matlab for save the figure to specific file format. I've managed to do this by essentially using a combination of fill3 (for the 13 bottom rectangles) and plot3 (for the sides) plots to draw each side of the probe, but the resulting code is very long and seems clumsy.

After executing the 1 st Matlab code, the NaN value is assigned to the variable A, and it is shown in figure 1.. After running through the inner loop, it plots y1,y2,y3,y4 over x=c in seperate plots using tiledlayout (2,2). When you read the hold documentation it optionally allows an axes handle to be specified (not a figure handle, which hold has nothing to do with). Every time MATLAB creates a figure, it is created with a default size, this is where the 419 and 560 dimensions come from which are the default height and width of the figure. For example, plot a line with a marker at the 10th data point. Assign the Axes objects to the variables ax1 and ax2. It generates the coefficients for the elements of the polynomial, which are used for modeling a curve to fit to the given data. Accepted Answer: KSSV. %Create a third figure figure() plot(x,w) To switch to a specific figure . New plots use the next colors and line styles based on the ColorOrder and LineStyleOrder properties of the axes. Matlab's 'hold' command determines whether the newly created graphic object will be added to the existing graph or will it replace the existing objects in our graph. y = sin (x); you could use. The explanation in the image () documentation is much better for what those values represent: please be sure to read the documentation as it is not quite what you would expect.
