Other MathWorks country sites are not optimized for visits from your location. I have attached a diagram of one vector arrow added artificially to show an example of the desired end result. What offset to use will require some thought that takes into account the various axes view properties such as camera target, and the DataAspect, and the [XYZ]Limit properties, so that after the projection due to the view is taken into account, the label becomes far enough away. (Originally posted on Doug's MATLAB Video Tutorials blog.) I tried surf(X,Y,Z) as well but matlab said: Z must be a matrix, not a scalar or vector. Introduction to Matlab Plot Multiple Lines.

For example, I have the coordinates for one point is 0.2,0.3,04 and for another point is -0.3,0.3,0.1. If you are using text() and the alignment is not enough, then you will need to add an offset to your coordinates. offset to use will require some thought that takes into account the various axes, such as camera target, and the DataAspect, and the [XYZ]Limit properties, so that.

Create separate line plots in the axes by specifying the axes object as the first argument to plot3. for i=15:55 for j=2:9 plot (i,j) end end for the above program, I want to display the coordinate of the point near the point in the figure. How would I use max(), num2str(), and text() to label the maximum point on a graph? How to label each point in MatLab plot? Put the XYZ coordinate value(s) of the desired point(s) into a separate worksheet. You can apply different data labels to each point in a scatter plot by the use of the TEXT command. You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. Unable to complete the action because of changes made to the page. Create separate line plots in the axes by specifying the axes object as the first argument to plot3.
