The discussion revolves around a user encountering an issue when plotting a column vector x=[1;1], resulting in a straight line instead of a single point. To display points correctly, the user is advised to use the 'o' marker in the plot command, such as plot(x,y, 'o'). However, the user needs to plot the x column vector derived from a separate calculation, which has not been shared. Suggestions include extracting the numbers from the column vector or using specific indexing commands like plot(x(1),x(2)) for individual elements or plot(x(1,:), x(2,:)) for multiple elements. The conversation emphasizes the importance of correctly formatting the plot command to achieve the desired visual output.
