Marker Size is the property that is used to specify the size of points and it is always a positive value. Accelerating the pace of engineering and science. for example:the user enters 1020 then a straight vertical line will be drawn at 1020 that meets the plot at some point and the coordinates of that point will be shown somehow. To plot multiple sets of coordinates on the same set of axes, specify at least one of X, Y, or Z as a matrix and the others as vectors. Adding markers to a line plot can be a useful way to distinguish multiple lines or to Sign in to answer this question. Define x, by specifying the range of values for the variable x, for which the function is to be plotted. How to mark a specific point in matlab plot?
