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.

Plot normal vectors of point cloud in 3d. info: Report informations about the point cloud to the command window. transform: Coordinate transformation of point cloud. export : Export activated points to a file. save: Save point cloud object as mat file. 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. For plots with many data points, it becomes visually crowded. t = 0:0.005:pi; plot(t, sin(3*t).*cos(t/2), 'p-' You can label points on a plot with simple programming to enhance the plot visualization created in MATLAB ®. You can also use numerical or text strings to label your points.

Typing plot(z) will plot the values of z against a list of 1,2,3,4,5, etc.. You can choose the color of the points, the type of line used, and the shape of points used by adding a string following the arguments of plot. This would look something like plot(x,y,'r-p'). In this case, the 'r' would make the line red, the '-' would make a straight line between the points, and the 'p' will make the. If you want to plot both markers and a line, you can use the plot function and specify a line style that includes marker symbols and a line style, such as '-x'. For example, this code plots a line with crosses at the data points For example, PLOT(X,Y,'y-',X,Y,'go') plots the data twice, with a solid yellow line interpolating green circles at the data points. The PLOT command, if no color is specified, makes automatic use of the colors specified by the axes ColorOrder property. The default ColorOrder is listed in the table above for color systems where the default is blue for one line, and for multiple lines, to cycle.
