We need to hold the contents of a figure with hold on the latest before we add the second line. command and the data won't erase when you plot something else. When you plot multiple data sets together in the same axes, MATLAB automatically assigns different colors (and possibly line styles and markers) to the plot objects. matlab lets you edit and annotate a graph directly from the window. n=0.1:0.1:1; x=0.1:0.1:3; while (n<1.1) a=1/3^n; I thought that using a for Loop like this would therefore plot a vertical line at each specified point, but Matlab returns: Link. Adding a "hold on" command means that anything that you plot will not clear the existing graph, but just plot on top of what is already there. If you don't turn the "hold" to "on" then the figure is overwritten with each iteration. "3D" is not a unique explanation, because this coud be a mesh, a surface, a path, a waterfall, a contour plot, perhaps some slices or a scatter plot. X = rand (100,6); figure; hist (X); Sr.No. Udemy Course: https://www.udemy.com/course/machine-learning-and-data-science-2021/?referralCode=E79228C7436D74315787Follow me on LinkedIn: https://www.linked.
